|
||
|
||
Mainly stuff to improve handling of TYPE_CODE_REF values.
|
||
* valops.c (value_addr): If taking the addres of a
|
||
TYPE_CODE_REF, just cast the object to the corresponding
|
||
TYPE_CODE_PTR. This yields correct C++ semantics, and
|
||
preserves the location information, which has the nice effect
|
||
that &(&R) given the location containing R.
|
||
* values.c (value_copy): Make non-static (used by value_addr).
|
||
* eval.c (evaluate_subexp_for_address): Use the default
|
||
scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
|
||
* valops.c (value_addr), eval.c (evaluate_subexp_for_address,
|
||
evaluate_subexp_with_coercion): Factor out some common
|
||
expressions into variables, for easier reading.
|
||
* findvar.c (locate_var_value): Remove code to handle
|
||
TYPE_CODE_REF - it should no longer be needed.
|
||
* valops.c (value_assign): Do a COERCE_REF on the
|
||
destination operand, for correct C++ semantics.
|
||
* valarith.c (value_x_binop): Ditto: De-reference C++
|
||
references in the arguments.
|
||
* valops.c: ANSI-fy: bcopy->memcpy, bzero->memset.
|
||
|
||
Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC.
|
||
* symtab.c (gdb_mangle_name): Recognize and handle
|
||
constructors specially.
|
||
* symtab.c (check_stub_method): Test for failure from
|
||
cplus-demangle by calling error() instead of seg-faulting ...
|
||
|
||
Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* defs.h: Add definition of null_cleanup()
|
||
|
||
* procfs.c: Many small changes to add base support for a new
|
||
"info proc" command (currently only printing of the address
|
||
space mapping is implemented) and allow iteration over the
|
||
address space mapping, calling an arbitrary function for each
|
||
mapping (used for shared library support).
|
||
|
||
* solib.c: Change all ifdefs that checked for "sun" to check
|
||
for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to
|
||
handle locating the debug base address even when not currently
|
||
stopped at the dynamic linker entry point.
|
||
|
||
* utils.c: Add null_cleanup() as a known function that does
|
||
nothing to serve as a base for possibly long cleanup chains
|
||
with no specific "first cleanup" to serve as an anchor.
|
||
|
||
* xm-sysv4.h: Add define of SVR4_SHARED_LIBS
|
||
|
||
Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
|
||
pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
|
||
these are all essentially the same as the versions
|
||
in ../include/opcode. The remaining *-opcode.h here
|
||
are not quite so obviously the same, and need study.
|
||
* arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
|
||
tahoe-pinsn.c, vax-pinsn.c: Change so these include
|
||
opcode/FOO.h (actually ../include/opcode/FOO.h)
|
||
instead of the recenntly departed opcode-FOO.h files.
|
||
* sparc-pinsn.c: Now that we're using the much tighter
|
||
opcode table in ../include/opcode/sparc.h, we shouldn't
|
||
need to sort the opcodes before dis-assembly.
|
||
|
||
* symtab.h, symmisc.c: Make cplus_struct_default be const.
|
||
* symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
|
||
* symmisc.c: Remove unused 'nfields' variable.
|
||
* buildsym.h: Add extern decl of unknown_symtype_complaint,
|
||
since it used used by partial-stab.h (included two places).
|
||
* partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
|
||
we should never hit the default case (until new stab codes
|
||
are added). Hence, we can leave the complaint in the
|
||
default case in even when DBXREAD_ONLY is off.
|
||
* partial_stab.h: Recognize a pair of N_SO stabs (one for the
|
||
directory, one for the filename proper) without peeking ahead.
|
||
* dbxread.c, mipsread.c: Because of previous change, don't need
|
||
ugly CHECK_SECOND_N_SO macro.
|
||
* buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
|
||
macro that invokes a function pointer in next_symbol_text_func.
|
||
* mipsread.c: Added comments various places to
|
||
explain what is going on.
|
||
* mipsread.c (parse_symbol): Support the new (SGI-specific?)
|
||
symbol types stStruct, stUnion, and stEnum.
|
||
Also, some fixes in the code for dealing with tags.
|
||
* mipsread.c: Change handling of startup_file_start and _end
|
||
- now just use the textlow and texhigh of a psymtab
|
||
to check if we've found the startup-file.
|
||
* mipsread.c: Replace s_idx by global cur_sdx in many places.
|
||
This is so mips_next_symbol_text can get at it.
|
||
|
||
Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
|
||
dbxread.c to symmisc and change name to add_psymbol_to_list.
|
||
Ditto for add_psymbol_addr_to_plist(). Also expand their
|
||
body to not use ADD_PSYMBOL_VT_TO_LIST.
|
||
|
||
* dwarfread.c: Remove add_psymbol_to_list() and convert usages
|
||
to the ADD_PSYMBOL_TO_LIST macro.
|
||
|
||
* ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
|
||
to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
|
||
|
||
* partial-stab.h, symfile.h: Move definitions of the macros
|
||
ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
|
||
partial-stab.h to symfile.h. They aren't stab specific.
|
||
Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
|
||
|
||
Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.in: Roll VERSION to 4.3.2.
|
||
|
||
Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
|
||
* m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
|
||
Include <opcode/FOO.h> instead of <FOO-opcode.h>.
|
||
|
||
* symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
|
||
dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
|
||
allocated when it is needed. Until it is needed, it points
|
||
to a shared statically allocated structure.
|
||
|
||
* buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
|
||
in read_ofile_symtab to recognize two initial N_SO stabs,
|
||
and let process_on_symbol handle it. This is cleaner, more
|
||
efficient, and lets mipsread.c share the same code.
|
||
|
||
* symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
|
||
and related macros to here ...
|
||
* dbxread.c: ... from here.
|
||
* symmisc.c: Move the "overflow" handling from
|
||
ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
|
||
* dwarfread.c: Re-write add_psymbol_to_list to use
|
||
ADD_PSYMBOL_VT_TO_LIST macro.
|
||
|
||
* mipsread.c: Extend mipsread.c to handle stabs-style symbols
|
||
encapsulated in ecoff symbols. This enable full g++ debugging.
|
||
* partial-stab.h: Move the code for pre-scanning symbols
|
||
and building psymtabs to an include file, out from dbxread.c.
|
||
This way, the same code can also be used by mipsread.c.
|
||
* dbxread.c, buildsym.h: Various changes to allow some functions
|
||
to be used by mipsread.c (also some arguable stylistic changes).
|
||
|
||
* tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
|
||
since mips-tfile puts relocatable addresses into LBRAC/RBRAC
|
||
stabs.
|
||
|
||
* mipsread.c: Replace code to handle ambiguous tag blocks.
|
||
Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
|
||
at types and offsets) if a tag is a struct, union, or enum.
|
||
Still patch it later if we find out for sure.
|
||
* mipsread.c: In various ways, replace Forin's
|
||
ideo-syncratic code by code that fits better with the
|
||
rest of gdb, for both stabs-based and ecoff-based symtabs.
|
||
E.g. use end_psymtab; don't do extra passes over FDR table to
|
||
pre-partition global data; don't use external symbols to
|
||
create static/global symbols (just put them in the
|
||
misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
|
||
sort psymtabs or symtabs; use obstacks more.
|
||
|
||
* symtab.c, mipsread.c, dbxread.c, buildsym.c:
|
||
ANSIfy: Replace bcopy by memcpy, bzero by memset.
|
||
|
||
Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* solib.c (locate_base): Fix uninitialized variable that was
|
||
causing return of random value to callee.
|
||
|
||
* config/mh-amix, config/mh-i386v4: Change to find alloca by
|
||
compiling and linking alloca.c, even when it is not strictly
|
||
required. Also arrange to link with -ltermlib rather than
|
||
-ltermcap.
|
||
|
||
* Makefile.in: Move TERMCAP definition to prior to inclusion
|
||
of host makefile fragments so it can be overridden.
|
||
|
||
Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* xcoffread.c (read_symbol_lineno): Logic error in incrementing
|
||
symbol table entry number. (From Metin Ozisik.)
|
||
|
||
Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
|
||
so compiles with native compilers (without builtin alloca) can
|
||
pick up the version from the bsd emulation library. However, we
|
||
search the standard C library first so we don't pick up lots of
|
||
other broken stuff from libucb.a, that we *don't* want.
|
||
|
||
* configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
|
||
Change svr4 references to sysv4.
|
||
|
||
* source.c: Move declaration of external function index to
|
||
front of file so it is in scope for all references.
|
||
|
||
* utils.c (error, fatal): Make definitions consistent with
|
||
defs.h declarations (declared as "volatile void").
|
||
|
||
Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
|
||
|
||
Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
|
||
sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
|
||
vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
|
||
|
||
Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
|
||
for these SVR4 systems.
|
||
|
||
* symfile.c (symbol_file_add): When verbose is set, print
|
||
the names of files from which symbols are being loaded, as
|
||
when from_tty is true.
|
||
|
||
* solib.c: Completely reorganized (rewritten) to support
|
||
SVR4 shared libraries in a manner very close to the original
|
||
SunOS implementation. This support is expected to change and
|
||
become more general at some future time. The SVR4 version
|
||
does not yet work for attached processes, for example.
|
||
|
||
* dwarfread.c: Arrange in dwarf_build_psymtabs() for the
|
||
relocation address to be valid whether or not symbols are
|
||
being read from a shared library or an executable. Use the
|
||
relocation address recorded in the psymtab when reading
|
||
full symbol tables (in read_ofile_symtab). Ensure that the
|
||
relocated address ranges are recorded in partial symtabs.
|
||
|
||
* elfread.c: Add new function elf_interpreter() to return the
|
||
string from the ELF ".interp" section. This is the interpreter
|
||
that the kernel tries to run and feed the executable to.
|
||
Expand arguments to record_misc_function to include a type arg.
|
||
Modify elf_symtab_read() to supply the type arg, and to do symbol
|
||
relocations for symbols read in from shared libraries.
|
||
|
||
* procfs.c: Add new functions proc_base_address() and
|
||
proc_address_to_fd(), used by shared library support.
|
||
|
||
* tm-svr4.h: Add macros to support SVR4 shared libraries.
|
||
Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
|
||
CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
|
||
|
||
Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
|
||
unused START_INFERIOR_HOOK.
|
||
|
||
* remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
|
||
to account for slow loading from floppies.
|
||
(eb_create_inferior): New fn, from eb_start and
|
||
nindy_create_inferior.
|
||
(eb_close): Only use log_file if nonzero.
|
||
(eb_xfer_inferior_memory): If not writing, then read!
|
||
(eb_read_inferior_memory, eb_write_inferior_memory): Return length.
|
||
(eb_kill): A new no-op.
|
||
(eb_mourn_inferior): Remove breakpoints, then generically weep.
|
||
|
||
Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
|
||
miscellaneous comparisons of integer with NULL that elicit
|
||
compiler warnings about comparison of integer with pointer, when
|
||
NULL is ((void *) 0) rather than just a bare 0.
|
||
|
||
Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
|
||
while we reset it, in case of problems. Print breakpoint number
|
||
in error messages.
|
||
|
||
* buildsym.c (read_struct_type): Avoid sun3 compiler bug with
|
||
foo[--n].
|
||
|
||
* source.c (find_source_lines): If getting file mod time fails,
|
||
don't warn.
|
||
|
||
* target.c (target_xfer_memory): If errno is set, return it,
|
||
rather than EIO.
|
||
|
||
Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
|
||
|
||
* Makefile.in: infodir belongs in datadir.
|
||
|
||
Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
|
||
|
||
* symtab.h (struct fn_field): Add new fields `is_private',
|
||
`is_protected', `is_stub', making room by reducing the size of
|
||
`voffset'.
|
||
(struct fn_fieldlist): Delete the fields `private_fn_field_bits'
|
||
and `protected_fn_field_bits'.
|
||
(TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
|
||
(SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
|
||
(TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
|
||
(TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
|
||
* valops.c, valprint.c, symtab.c: All callers updated.
|
||
|
||
* buildsym.c (read_struct_type): Delete the `visibility' field
|
||
from `struct next_fnfield', and rework code so that visibility
|
||
info is stored into the fn_field directly. Also, hacked to set
|
||
TYPE_FN_FIELD_STUB for both static and normal member functions.
|
||
|
||
Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* i386-tdep.c: Fix a problem on i386 systems where buffered code
|
||
stream access was failing to take into account the minimum size
|
||
granularity of the code section. For now, the buffering is simply
|
||
disabled. There is a similar problem in the i386 disassember code
|
||
that has not yet been fixed (FIXME).
|
||
|
||
* gmalloc.c: Use macros to hide some of the ugly casting required
|
||
in the previously applied fix for pointers with high bits set.
|
||
|
||
Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.in: Roll VERSION to 4.3.1.
|
||
|
||
Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
GDB-4.3 release!
|
||
|
||
* Makefile.in: Roll VERSION to 4.3
|
||
* README, TODO, WHATS.NEW, depend: Update.
|
||
|
||
* inflow.c (terminal_inferior): Avoid error msg if attached.
|
||
|
||
* gmalloc.c: Fix bug that causes malloc & free to
|
||
fail on systems where pointers have the high bit set (0x800efcf0
|
||
for example). The problem is that the difference between two
|
||
pointers is a signed integer, so the computation
|
||
|
||
(char *) 0x800efcf0 - (char *) 0
|
||
|
||
yields a negative value. The sign of the result of the modulus
|
||
operator is machine dependent for negative operands, thus it is
|
||
possible for it to end up negative. From Fred Fish.
|
||
|
||
Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
|
||
|
||
* Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
|
||
added clean-info. added some standards.text support and made it
|
||
look like our other Makefiles.
|
||
|
||
* configure.in: mark this directory target dependent. configure
|
||
now runs entirely in objdir so make existence tests and
|
||
references against ${srcdir}.
|
||
|
||
Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c (enum_type, struct_type): Fixes for opaque and
|
||
anonymous enumerations, structures, and unions. Now passes all
|
||
the current gdb test suite tests.
|
||
|
||
Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
|
||
|
||
* Makefile.in: idestdir and ddestdir go away. Added copyrights
|
||
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
|
||
and mandir now keyed off datadir by default.
|
||
|
||
Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
|
||
mid-line, be more careful about possibly advancing to the next line.
|
||
|
||
Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
|
||
|
||
* cplus-dem.c (cplus_demangle): Call `string_need' when
|
||
null-terminating a partially-computed string.
|
||
|
||
Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
|
||
symbol to the symbol table for each member of the enum.
|
||
|
||
* dwarfread.c (struct_type): Build a correct TYPE_NAME.
|
||
|
||
* dwarfread.c (add_enum_psymbol): New function to extract enum
|
||
member names and add them to the partial symbol table while
|
||
building partial symbol tables.
|
||
|
||
Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* symtab.c (check_stub_method): Must allocate two extra argument
|
||
slots (one for `this', one for arglist terminator).
|
||
|
||
Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* inflow.c (child_terminal_info): Supply missing '"' character.
|
||
|
||
* buildsym.c (define_symbol): Supply missing parenthesis.
|
||
|
||
Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* coredep.c (fetch_core_registers): Fencepost error. Fixed by
|
||
Jay Lepreau <lepreau@cs.utah.edu>.
|
||
|
||
* inflow.c: Remember whether GDB has a terminal. Avoid switching
|
||
terminals back and forth if we don't have one.
|
||
|
||
* c-exp.y (parse_number): Zero is not an unsigned int constant!
|
||
* dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
|
||
|
||
Improve type parsing.
|
||
* buildsym.c (define_symbol, read_range_type): Add
|
||
long_kludge_name that passes the names of range types being
|
||
defined, down to where we must choose between 'int' and 'long'
|
||
variants. This fails on Sun C anyway since the compiler itself is
|
||
confused between int and long.
|
||
(read_array_type, cleanup_undefined_types): Correct the size of
|
||
array type whose element-type size isn't immediately known.
|
||
|
||
Early preparation to blow away many builtin types, building them
|
||
on the fly as needed. Don't compare types to builtin types with
|
||
==; examine the relevant fields instead.
|
||
* coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
|
||
* buildsym.c (define_symbol, case 'p'): Avoid ==.

|
||
target types are the same.
|
||
* valprint.c (val_print): I finally understand arrays, remove FIXME.
|
||
|
||
* symmisc.c (printpsyms_command): Reduce redundancy, and put all
|
||
addresses in GDB itself into parens for easy cleanup and diffing.

|
||
|
||
* dwarfread (enum_type): Arrange for the order of enumeration

|
||
Print symbol name, not its number.
|
||
Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
|
||
someday should go in a clipper target config file.
|
||
|
||
* symfile.c (compact_misc_function_vector): Handle empty vector.
|

|
||
|
||

|
||
when configured for cross debugging. FIXME, this needs a more
|
||
general solution.
|
||
|
||
Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mips-tdep.c (init_extra_frame_info): Float register

||
'i' has gdb-internal number 'FP0+i', not '32+i'.

|
||
TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.

|
||
|
||
* coffread.c (anonymous unions): Allocate a cplus structure.

|
||
at #define's, followed by defs.h and then the tm-file.

|
||
Late-model BSD 'make's don't cope with them.

Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.in: Roll new files into various lists.
|
||
|
||
Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c (struct_type): Must initialize the c++ specific
|
||
portion of union types as well as struct types, since gdb attempts
|
||
to reference the c++ specific info for both types.
|
||
|
||
Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
|
||
|

Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Remove gdb/hp-include. Support for HP a.out oddities should be

|
||
|
||
* infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
|
||
|
||
* configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
|
||
Makefile fragments for various hosts and targets now come from
|
||
gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
|
||
other config setups.
|
||
|
||
* rs6000-pinsn.c, rs6k-opcode.h: Clean up.
|
||
* rs6k-opcode.def: Delete.

|
||
more.
|
||
|
||
Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c (enum_type, struct_type): Ignore names invented by
|
||
helpful compilers for anonymous structs, unions, and enums.
|
||
|
||
* c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
|
||
yy_yyv, so multiple parsers produced by SVR4 versions of yacc
|
||
can coexist in the same executable without collision.
|
||
|
||
* symtab.h: Add declaration for lookup_template_type() to kill
|
||
compiler warnings about conversions from int to pointer.
|
||
|
||
Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* procfs.c: Move inclusion of defs.h to before param.h, as in
|
||
all the other source files that include both. This is required
|
||
to supply some typedefs that are used in files included by param.h.
|
||
|
||
* m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
|
||
skipping function prologues, ala the other cpu families (i386,
|
||
mips, m88k, etc). Add the ability to skip movm and fmovm
|
||
instructions in the prologues. Still needs support for profile
|
||
(-p compiled) prologue sequences (FIXME).
|
||
|
||
* tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
|
||
m68k prologue skipping function by default.
|
||
|
||
* tm-altos.h, tm-isi.h: Continue to use the old definition of
|
||
SKIP_PROLOGUE.
|
||
|
||
Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||

||
FRAME_CHAIN_COMBINE.

|
||
of defaultable things.
|
||
* tm-m88k.h: New file, common to all Moto 88k target configs.
|
||
Derived from tm-delta88.h.
|
||
* tm-delta88.h: Use it.
|
||
* xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
|
||
* xm-delta88.h: Use it.

default.
|
||
* coffread.c: Remove tdesc stuff.
|
||
* tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
|
||

|
||
|
||
Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* source.c (open_source_file): If openp fails, try again
|
||
using just the base (non-directory) part of the filename.
|
||
This solves various annoying problems, such as when the
|
||
source was compiled with an absolute pathname - and the
|
||
source files have moved. Or if the source was compiled
|
||
using a relative pathname, it can be more convenient
|
||
to just specific the source directory to the dir command.
|
||
|
||
Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
|
||
|

|
||
AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
|
||
and AT_is_external.
|
||
|
||

|
||
`struct cplus_struct_type'. Now takes 10% less memory. Many
|
||
macros changed.
|
||
* symtab.c (init_type): Don't set fields belonging to
|
||
TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
|
||
* buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
|
||
TYPE_CODE_STRUCT.
|
||
(read_struct_type): Ditto. Also, add comments about how we can
|
||
deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
|
||
* coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
|
||
TYPE_CODE_STRUCT.
|
||
(read_struct_type): Ditto.
|
||
* dwarfread.c (struct_type): Ditto.
|
||
|
||
* symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
|
||
(lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
|
||
(lookup_reference_type): Ditto.
|
||
|
||
* cplus-dem.c: Many changes made to handle decoding of
|
||
ANSI-mangled names.
|
||

|
||
as well.

|
||
|
||
Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* symfile.c: Add function compact_misc_function_vector() to
|
||
remove duplicate misc function vector entries. See comments
|
||
in source for why this is necessary/desirable.
|
||
|
||
* dwarfread.c: Add misc function type parameter to internal
|
||
record_misc_function(). Remove calls to init_misc_bunches()
|
||
and condense_misc_bunches(), these are now done in elfread.c.
|
||
|
||
* elfread.c: Add support for reading bfd canonical symbol tables
|
||
and generating misc function vector entries for global and
|
||
absolute symbols. Do calls to init_misc_bunches() and
|
||
condense_misc_bunches() where they will enclose all calls to
|
||
record_misc_function(), including those in dwarfread.c.
|
||
|
||
Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)

|
||
texi2roff conversion.

|
||
|
||

|
||
|
||
* m88k-tdep.c: Blow away all tdesc stuff.
|
||
Provide functions for all the frame-related macros in

(examine_prologue, frame_find_saved_regs, skip_prologue): borrow
|
||
from i960-tdep.c and adapt to the function prologues on the 88k.

FIXME: frame_locals_address should go away.
|
||
|

|
||
SP_REGNUM.
|
||
|
||
* xm-88k.h: Eliminate lots of library dependencies, now handled
|
||
in libiberty. Eliminate KDB nonsupport.
|
||
|
||
* doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
|
||
|
||
|
||
* stack.c (frame_info): Mark frameless functions.
|
||
Print locals address (FIXME, remove if same).
|
||
* blockframe.c: Comment changes, FIXME after.
|
||
* coffread.c: Even without TDESC, need to zap "@" symbols.
|
||
Don't register for wierd format names; change the names in BFD.

flags since they are no longer used.
|
||
|
||
Fixes to support C++ methods with functional parameters.
|
||
* c-exp.y (func_mod rule): Allow (and ignore) list of parameter
|
||
types in a function type.
|
||
* eval.c (parse_and_eval_type), value.h: New function,
|
||
parse_and_eval_type, is based on old code from check_stub_method.
|
||
But don't actually evaluate the cast, since that calls
|
||
value_cast(), whcih may fail. Just extract the type
|
||
from the parsed expression.
|
||
* values.c (check_stub_method): While looping through the
|
||
arguments, adjust depth *after* parameter has been handled.
|
||
Replace call and setup of parse_and_eval with new function
|
||
parse_and_eval_type.

Change all instances of use of fixed args concat() to variable
|
||
args concat() now located in libiberty.

fetch_core_registers() function for core file support.
|
||
|

||
* dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
|

whenever it is not supplied by coredep.c
|
||
|
||

|
||
|
||
Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
|
||
|
||
* Makefile.in: link with libiberty after libreadline, since
|
||
readline might want something in libiberty.
|
||
* m88k-xdep.c: Fixed the register offsets in the ptrace_user
|
||
struct for BCS 88k machines.
|
||
* xm-m88k.h: don't define USIZE if already defined.

|
||
|
||
* tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
|
||
READ_MIPS_FORMAT, which have been unused since BFD. Still
|
||
remaining is COFF_NO_LONG_FILE_NAMES.
|
||
* tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
|
||
function calling code moved to m68k-tdep.c.
|
||
|
||
Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* coffread.c: Eliminate c_nsyms in favor of c_naux.
|

Complain if no auxents on .bf and .ef FCN symbols, and assume
|
||
lots of line numbers.
|
||
(init_linenos, enter_linenos): Use a sentinel at the end of the
|
||
read-in linenos, to make for a fast, safe loop-end test.
|
||
|
||
Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
|
||
|
||
* coffread.c (read_coff_symtab): coffread used to rely on the
|
||
x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
|
||
function. Two of the formats I'm using (29k and 88k) don't seem to
|
||
set it. Ths patch to fcn_last_line and (enter_linenos) is an
|
||
attempt to use the actual size of the linno table in the file to set
|
||
the number of linenos to process.
|
||
|
||
Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
|
||
|
||
* Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
|
||
mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
|
||
are created in place, so the mv fails, then the make continues.
|
||
|
||
Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
Add C++ as a separate language.
|
||
* defs.h (enum language): Add language_cplus.
|
||
* dwarfread.c (end_symtab): Support language_cplus.
|
||
* c-exp.y: Add new struct language_defn cplus_language_defn.
|
||
Don't set c to be the default language (see main.c).
|
||
* c-exp.y (yylex): Only look for field of this if
|
||
language is C++. (First difference from C!)
|
||
* language.c: Add case branches for C++ (currently, all
|
||
the same as C). Also, add c++ to "usage" note for "set lang".
|
||
* valprint.c (typedef_print). Add case branches for C++.
|
||
* main.c (main): New way to set initial language: Look at
|
||
file extension of psymtab containing main(). (Same as we
|
||
do for symtabs, but avoid loading the symtab yet.)
|
||
* symtab.c: New routine find_main_psymtab(), used by main()
|
||
to set initial language.
|
||
* symfile.c (allocate_symtab): Move code for mapping file
|
||
extensions-> languages to new deduce_language_from_filename().
|
||
|
||
Fix a C++ problem when looking for methods in super-classes.
|
||
There was confusion between base and derived types.
|
||
* valops.c (value_fn_field): Change function interface.
|
||
* values.c: Use new value_fn_field interface.
|
||
|
||
Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* infrun.c: Fixed typo in comment.
|
||
* utils.c: All the v*fprintf emulation is now in libiberty,
|
||
so we can get rid of some junk.
|
||
* xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
|
||
xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
|
||
* m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
|
||
type operands, as used by branch instructions.
|
||
* gmalloc.c: Fix prototype of memcpy.
|
||
* elfread.c: Comment out register_addr, since it conflicts
|
||
with the one in coredep.c.
|
||
* buildsym.h: Remove extern declarations of two functions
|
||
that are really static in buildsym.c.
|
||
* tm-mips.h: Add symbolic names for more registers.
|
||
* mips-xdep.c (store_inferior_registers): Use new register names.
|
||
* xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
|
||
only used for core files, not ptrace. Therefore,
|
||
the KERNEL_U_ADDR hack is no longer needed.
|
||
The mapping to ptrace number is now in in mips-xdep.c.
|
||
* mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
|
||
mapping from the old REGISTER_U_ADDR), and use it
|
||
in {fetch,store}_inferior_registers.
|
||
* mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
|
||
* mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
|
||
Save/restore FP regs correctly (?).
|
||
* dbxread.c: Remove duplicate define_symbol and type_synonym_name
|
||
(these had been previously moved to buildsym.c).
|
||
Hence, define_symbol becomes extern instead of static.
|
||
* buildsym.c (read_struct_type): Comment out bogus handling
|
||
of C++ operator methods. Minor hacking of reading of class
|
||
contexts. Make define_symbol non-static, so dbxread.c can call it.
|
||
|
||
Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
|
||
filename with error messages.
|
||
* stack.c (frame_select_command): Rename to select_frame_command
|
||
to avoid "fr" and "fra" having nonunique completions.
|
||
* symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
|
||
(symfile_init): Print file format name when unable to handle it.
|
||
(free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
|
||
* symmisc.c (free_symtab): Only free linetable if nonzero.
|
||
* symtab.h: Remove obsolete BLOCKLIST macros.
|
||
|
||
Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
|
||
that stop_step is 1 at bottom of main loop. I don't know why this
|
||
needs to be done, but it helps me sleep better at night.
|
||
|
||
Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* main.c (initialize_history): Read history after reading all
|
||
init files.
|
||
|
||
Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* buildsym.c: Break out initial malloc sizes.
|
||
(record_line): Record directly in a subfile. Alloc on demand.
|
||
(compare_line_numbers): Add from xcoffread.c.
|
||
(end_symtab): New params say whether to sort pendings and
|
||
linetable. Patch block stabs if defined. Shrink linetable before
|
||
allocating the symtab.
|
||
* buildsym.h: Delete line_vector* and prev_line_number. Add
|
||
global_stabs and file_stabs for xcoffread.
|
||
* dbxread.c (start_subfile): Move to buildsym. Change above calls.
|
||
* symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
|
||
* symmisc.c, symtab.c: Cope with null LINETABLEs.
|
||
|
||
* blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
|
||
* tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
|
||
tm-sparc.h: Accept fromleaf parameter.
|
||
* c-exp.y (yyerror): Pass error message if given.
|
||
* configure.in: Add rs6000 host and target.
|
||
* inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
|
||
* symfile.h (entry_point): Add.
|
||
|
||
Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
|
||
|
||
* buildsym.c: New file. Breaks out symbol-table-building routines
|
||
from dbxread.c, so they can be shared with xcoffread.c.
|
||
* buildsym.h: New file. Declarations for buildsym.c users.
|
||
* dbxread.c: Remove large chunks into buildsym.c.
|
||
* Makefile.in: Add buildsym.c and buildsym.h.
|
||
|
||
* symfile.c (syms_from_bfd): New routine.
|
||
(add_symbol_file): Call it to do the real work.
|
||
(syms_from_bfd): Initialize entry_point before calling symfile_init.
|
||
* symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
|
||
Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
|
||
|
||
Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
|
||
|
||
* cplus-dem.c (cplus-demangle): added support for templates, static
|
||
data, and the new (correct) mangling for destructors.
|
||
|
||
* dwarfread.c: (dwarfwarn): created a varargs version of
|
||
dwarfwarn, for non __STDC__ compilers.
|
||
|
||
* c-exp.y: (yylex): added match for "template" token.
|
||
(typebase): added TEMPLATE name '<' type '>' clause, for explicit
|
||
specification of template types.
|
||
|
||
* symtab.c: (lookup_template_type): new function for finding
|
||
templates in symbol table.
|
||
(type_name_no_tag): changed to explicitly check for s/u/e at the
|
||
beginning of the symbol - if it is a template, none of these will
|
||
be there (but the name will still contain spaces.)
|
||
|
||
Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
Various fixes to improve g++ debugging.
|
||
* symtab.h: Add is_const and is_volatile flags for each method.
|
||
These are bit fields - take their space from voffset,
|
||
which shrinks to 30 bits. Since voffset is now a bitfield,
|
||
make it unsigned for portability. This changes its interpretation
|
||
slightly: Static methods now have voffset 1 instead of -1,
|
||
and virtual offsets start at 2, not 1.
|
||
* symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
|
||
since it now returns an entire magled method name, not just
|
||
the type part. This avoids some duplication.
|
||
It also allows us to correctly mangle const and volatile
|
||
methods (using the new is_const and is_volatile bit fields
|
||
mentioned above).
|
||
* valprint.c (type_print_base), values.c (check_stub_method):
|
||
Simplify by using new gdb_mangle_name.
|
||
* values.c (value_headof): Fix to correctly handle single
|
||
inheritance (actually two fixes, either of which suffices).
|
||
* dbxread.c (read_struct_type): Handle const and volatile
|
||
method specifiers.
|
||
* dbxread.c (read_struct_type): Yet one more place where
|
||
we must handle '\\' continuations.
|
||
* valprint.c (vtbl_ptr_name): Add final '\0'.
|
||
|
||
Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
|
||
short return values for sparc and 68k. Patch from Paul Eggert.
|
||
|
||
* coffread.c, coredep.c, i386-xdep.c: install patches for
|
||
SysV/386 3.2 from Mauro DePalma.
|
||
|
||
Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* core.c (core_file_info), exec.c (exec_file_info): Print file
|
||
type. Use printf_filtered.
|
||
|
||
* valops.c (value_fetch_lazy): Avoid 0-length fetches.
|
||
|
||
Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c: Add casts to remove compiler warnings.
|
||
|
||
* tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
|
||
tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
|
||
tm-sun3.h: Remove locally duplicated code for calling functions
|
||
in the inferior. The only differences were in the specific trap
|
||
vectors used and whether or not an fpu was present. These are
|
||
now handled by appropriate definitions of BPT_VECTOR and
|
||
HAVE_68881 respectively. Other minor obvious cleanups.
|
||
|
||
* valops.c: Correct a minor misspelling.
|
||
|
||
* utils.c: Remove local BSD/USG hacks that are now in libiberty.
|
||
|
||
* dwarfread.c: Remove prototype for dwarfwarn. Does not work
|
||
with <varargs.h>.

* stack.c (frame_command): Always print. Use new
|
||
frame_select_command to select a frame without printing.
|
||
|
||
* dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
|
||
|
||
Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c: New file for DWARF debugging format support.
|
||
|
||
* elfread.c: New file for ELF object file format support.
|
||
|
||
* procfs.c: New file for SVR4 /proc (process file system) support.
|
||
|
||
* tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
|
||
Amiga UNIX support.
|
||
|
||
* xm-svr4.h, tm-svr4.h: New files for SVR4 support.
|
||
|
||
* xm-m68k.h: New file for host machines with m68k cpu.
|
||
|
||
* Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
|
||
Add elfread.o and dwarfread.o to OBS.
|
||
|
||
* symfile.h: Add "elf" to list of supported formats in comment.
|
||
|
||
* c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
|
||
types to gdb, builtin_type_long_double, builtin_type_complex, and
|
||
builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
|
||
TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
|
||
TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
|
||
TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
|
||
types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
|
||
|
||
* infrun.c: When using SVR4 /proc interface instead of ptrace(),
|
||
call proc_set_exec_trap() to setup child to stop at first instruction.
|
||
|
||
* inftarg.c: When using SVR4 /proc interface, call proc_wait()
|
||
rather than wait().
|
||
|
||
* m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
|
||
supply_fpregset(), and fill_fpregset(), which are machine
|
||
dependent support routines for SVR4 /proc interface.
|
||
|
||
* utils.c: Add warning_setup() and warning(). Warning() behaves
|
||
the same as error() except that it returns normally rather than
|
||
jumping back to command level. Modules that don't want to call
|
||
warning() for some reason, but want to produce their own warnings,
|
||
can call warning_setup() to ensure compatibility with the way
|
||
warning() and error() deal with the terminal.
|
||
|
||
* symtab.c: Make internal errors produce more useful messages.
|
||
|
||
* tm-68k.h: Move code that is duplicated in almost every single
|
||
m68k based machine's configuration files to this common file.
|
||
Duplications in the configuration files still need to be removed
|
||
(FIXME).
|
||
|
||
* infrun.c (child_create_inferior): System V versions must call
|
||
setpgrp() with no arguments, to comply with prototyping typically
|
||
in <unistd.h>.
|
||
|
||
* munch: Add support for SVR4 style nm output.
|
||
|
||
* dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
|
||
file specific fields from the partial symbol table structure and
|
||
replace them with a pointer to private data for each different
|
||
flavor of object file reader to initialize appropriately.
|
||
|
||
Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
|
||
and previous.
|
||
|
||
* mipsread.c (fixup_undef_type): New function. If a struct /
|
||
union / enum is defined in a header file but nowhere else used,
|
||
(by typedefing, pointer referencing or declaration) the mipsread code
|
||
builds the complete tree for the structure but leaves its code as
|
||
TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
|
||
Guess its type based on the details of the members.
|
||
|
||
Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* infrun.c (wait_for_inferior): Check return value from
|
||
find_pc_line.
|
||
|
||
Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* infrun.c (wait_for_inferior): fix stepi/nexti that was broken
|
||
by my last edit to this routine.
|
||
|
||
Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
|
||
FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
|
||
the values before putting them into the dummy code. (From Peter
|
||
Schauer)
|
||
|
||
Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
|
||
|
||
* configure.in: added ebmon target.
|
||
|
||

dec3100 to decstation.
|
||
|
||
Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
|
||
|
||
* doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
|
||

|
||
due to Larry Breed
|
||
|
||
Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move

|
||
generic routines for calling inferior functions.
|
||
|
||

||
Make them available as `show copying' and `show warrantee' also.
|
||

|
||
|
||
Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* mach386-xdep.c: Even when cross-compiling, leave in the
|
||
core-file reading code.
|
||
* core.c (get_core_registers): Avoid coredump if no .reg section.
|
||
|
||
Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
|
||
This avoids coredumps under `set print object on' in value_headof
|
||
(called erroneously by value_from_vtable_info) for `p &struct'
|
||
or `p *struct'. From Peter Schauer.
|
||
|
||
Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.in: Roll version to 4.1.2.
|
||
* dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
|
||
size from BFD (but, FIXME, we don't yet read external nlists's and
|
||
convert them to internal nlists's before handling them -- we still
|
||
assume they have the same size and alignment.) Use SET_NAMESTRING
|
||
everywhere useful.
|
||
* exec.c (exec_file_command): Move dead coff-encapsulation code
|
||
to BFD.
|
||
* m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.

* coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
|
||
vestiges of typevectors, which were for symsegs and are no longer
|
||
used. (From a question by Eliot Dresselhaus
|
||
<dresselh@RFT30.nas.nasa.gov>).
|
||
|
||
Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* dbxread.c, coffread.c: static-ize functions that were
|
||
gratuitiously external. (From Fred Fish.)
|
||
|
||
* c-exp.y: sym->class to SYMBOL_CLASS (sym).
|
||
|
||
* dbxread.c (dbx_lookup_type): Keep doubling size of typevector
|
||
until it is large enough.
|
||
|
||
* dbxread.c (read_type): Handle error case slightly better.
|
||
Make complaint message not C++-specific.
|
||
|
||
Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* infrun.c (wait_for_inferior): Fix step/next so that you only
|
||
stop at the beginning of a new line. This fixes various problems
|
||
with for loops, nested if-else's and switch statements.
|
||
|
||
Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
|
||
between symtabs and psymtabs become ordinary error()s.
|
||
|
||
* dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
|
||
properly, making "end pc" correct in shared lib psymtabs.
|
||
(From Guy Harris <guy@auspex.com>.)
|
||
|
||
Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* dbxread.c: Enable, but soften, const_vol_complaint.
|
||
(read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
|
||
Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
|
||
should be file-scope, not global.
|
||
(read_struct_type): Remove ancient multiple-inheritance warning.
|
||
(read_range_type): Check base type, complain & patch if undefined.
|
||
* stack.c (frame_info): Demangle the function name in `info stack'.
|
||
(From Peter Schauer)
|
||
|
||
Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* eval.c (evaluate_subexp_for_address): Don't use
|
||
TYPE_POINTER_TYPE directly (it might be zero if this type has
|
||
never had a pointer created before); use lookup_pointer_type.
|
||
* symtab.c (lookup_method_type): Arguments were swapped in all
|
||
callers, so fix it here. I'm amazed this worked at all!
|
||
|
||
Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* c-exp.y, m2-exp.y: Define more yysymbols that happen to be
|
||
"bss" rather than "data" symbols, but which still conflict.
|
||
* m2-exp.y: Lint.
|
||
|
||
* coffread.c (coff_symfile_read): Use xmalloc, not malloc.
|
||
* core.c (core_files_info): Shorten output.
|
||
* exec.c (exec_files_info): Ditto.
|
||
(build_section_table): Ignore zero-length sections.
|
||
* language.c, printcmd.c: Lint.
|
||
* language.h (get_frame_language): Declare.
|
||
* saber.suppress: update.
|
||
* stack.c (find_relative_frame): Remove complex code that was
|
||
#if 0'd, stick with simple code. Lint.
|
||
* saber.suppress: Update a bit.
|
||
* symfile.c (add_symbol_file_command): Add "?" to question.
|
||
* utils.c (parse_escape): Avoid \a due to bdead compilers.
|
||
* value.h: Declare typedef_print.
|
||
|
||
* valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
|
||
kludgey.
|
||
|
||
* nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
|
||
(Reported by Mark Peek <mark@imagen.com>.)
|
||
|
||
* solib.c (solib_map_sections): Relocate all sections, even
|
||
though only the text section's size is tracked. Mark ld_text
|
||
for eventual elimination as we generalize to N sections.
|
||
|
||
* infrun.c (wait_for_inferior): Don't check if the PC is in a
|
||
call_dummy if we were stopped by a random signal that is being
|
||
passed to the program. This produced wierd results when calling
|
||
functions in the inferior and signals (e.g. SIGALRM) were in use.
|
||
|
||
Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* infrun.c (IN_SIGTRAMP): Not parenthesized properly.
|
||
Bugfix from Paul Eggert <eggert@twinsun.com>.
|
||
* tm-ultra3.h (IN_SIGTRAMP): Ditto.
|
||
* valprint.c (print_floating): Print 9 digits for IEEE floats.
|
||
From Paul Eggert.
|
||
|
||
Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.in: Roll VERSION to 4.1.1.

||
hex conversion.
|
||
|
||
Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
GDB-4.1 release!
|
||
|
||
* Makefile.in (VERSION): Set to 4.1.
|
||
* language.c (set_language_command): Print useful help message,
|
||
and restore the language string after giving help.
|
||
* valprint.c (typedef_print): Print typedef in C or M2.
|
||
* symtab.c (list_symbols): Use it.
|
||
* main.c (main): Avoid any output before (gdb) prompt when -q.
|
||
* language.c (set_language_command): Handle errors by restoring
|
||
the language string to its current state (fix from A. Beers).
|
||
* doc/gdbint.texinfo: Roll in information from README. Rearrange
|
||
"how to install" and "how to print the doc" stuff so it drops
|
||
easier into README.
|
||
* configure.in: Rename rtpc CPU to romp to match config.sub.
|
||
* README, WHATS.NEW, TODO: Update for gdb-4.1.
|
||
|
||
Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
|
||
|
||
* doc/gdb.texinfo: Updates from ChangeLog. set/show write,
|
||
autoloading shared libs, copyright etc on GDB startup, clean up $_
|
||
and $__ index refs, set/show listsize and related updates to list
|
||
cmd. New host/target configs.
|
||
|
||
Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
|
||
|
||
* doc/Makefile: generate aux version-no file doc/gdbVN.m4
|
||
from main Makefile.in version definition
|
||
doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
|
||
GDB version no refs
|
||
Makefile.in (setup-to-dist): generate doc/gdbVN.m4
|
||
|
||
* doc/gdb.texinfo: merge new language-switching and lang-specific
|
||
doc by Andrew Beers
|
||
|
||
Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
|
||
compilers (which may lack stddef.h).
|
||
|
||
Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
|
||
N_WARNING are the same except for the N_EXT bit, so just use their
|
||
values alone, rather than OR-ing them with N_EXT.
|
||
|
||
Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* mipsread.c (parse_lines): Deal with negative extended line
|
||
offsets correctly.
|
||
|
||
* c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
|
||
global symbol conflicts.
|
||
|
||
Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* .gdbinit: Move 'set complaints' to top, so it runs even in
|
||
case we aren't debugging GDB.
|
||
* language.c (_initialize_language): Fix type check and range
|
||
check documentation strings.
|
||
* utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
|
||
language.c can use it. (Though language.c should really not be
|
||
handling warnings/errors the way it does, FIXME.)
|
||
* symtab.c (lookup_primitive_type): const lint.
|
||
|
||
Bugfix from Peter Schauer:
|
||
* source.c (lines_to_list): Make signed, to avoid comparison
|
||
going unsigned and complaining that -3 is too high for 21 lines.
|
||
* stack.c (lines_to_list): Ditto.
|
||
|
||
Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.in (HFILES): Add minimon.h.
|
||
(VERSION): Roll version number to 4.0.95.
|
||
(gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
|
||
New rules for building distributions. Normal distribution
|
||
is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
|
||
one level up from here; it calls make-proto-gdb.dir to build a
|
||
directory `proto-gdb' which is an image of the release. The old
|
||
`gdb.tar.Z' rule still works too.
|
||
* config.sub, configure: Roll in latest from ..
|
||
|
||
Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
|
||
|
||
* doc/gdbint.texinfo: Reorder contents; reorganize new-host,
|
||
new-target, and new-config chapters; fix minor typos; come closer
|

Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
|
||
* mipsread.c (parse_partial_symbols): Enter the name of all
|
||
structs/unions... into the psymtab so we can access them if the
|
||
symtab is not read in.
|
||
* mips-tdep.c: Remove some unneeded #includes.
|
||
* xconfig/dec3100: Add HAVE_STRSTR.

Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Add Andrew Beers' changes for Modula-2 support. His ChangeLog
|
||
entries are enclosed herein. Not all of these changes
|
||
have been merged into the master GDB sources -- check the
|
||
ChangeLog above here for the merge log.
|
||
|
||
Mon Jun 3 17:05:45 EDT 1991
|
||
|
||
m2-exp.y Created. Tested outside of GDB for a few days. Proper
|
||
operators were added, C specific operators and tokens
|
||
removed. yylex() revamped to some extent. Still things
|
||
missing from the grammar, such as sets.
|
||
Tested for two weeks in GDB v3.5.
|
||
|
||
Tue Jun 11 17:23:48 EDT 1991
|
||
|
||
m2-exp.y Added boolean constants TRUE and FALSE to the grammar
|
||
so they are built-in. Sort of a hack.
|
||
|
||
Fri Jun 14 12:53:51 EDT 1991
|
||
|
||
m2-exp.y Added range checking for numeric constants. Any numeric
|
||
constant is assumed to be of builtin type INTEGER unless:
|
||
(1) it is octal or hexadecimal, in which case it is a
|
||
CARDINAL; (2) it is too big to fit into an INTEGER, in
|
||
which case it is a CARDINAL.
|
||
eval.c Added simple range checking for +, -, and * on integers.
|
||
Doesn't work very well for *, since 6 * 1,000,000,000 =
|
||
1,705,032,704, which fails the simple test of result >=
|
||
first_operand, no matter in what order the operands are.
|
||
|
||
Tue Jun 18 14:11:30 EDT 1991
|
||
|
||
Broke the parser into parts, one containing the C grammar and the other
|
||
containing code to be shared by all of the grammars.
|
||
|
||
The following files no longer exist:
|
||
|
||
expread.y
|
||
expread.tab.c
|
||
|
||
The following files were added:
|
||
|
||
c-exp.y (The C grammar)
|
||
m2-exp.y (The Modula-2 grammar)
|
||
parser-code.c (Code that is shared by the above grammar)
|
||
parser-code.h
|
||
parser-defs.h
|
||
|
||
Makefile.dist Changed to reflect the above dependencies. NOTE: It is
|
||
now necessary to use the Bison compiler compiler, since it
|
||
will generate function/variable prefixes other than yy.
|
||
|
||
Tue Jun 18 16:47:49 EDT 1991
|
||
|
||
symtab.[ch] Added the external variable working_lang, than holds the
|
||
value of the current working language.
|
||
Added the ennumerated type language_mode, with the values
|
||
language_auto and language_manual, the former meaning that
|
||
GDB sets working_lang as needed, and the latter meaning
|
||
that the value of working_lang is totally under user
|
||
control.
|
||
symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
|
||
REAL, BOOLEAN and CHAR. Also added the type codes
|
||
TYPE_CODE_BOOL and TYPE_CODE_CHAR.
|
||
utils.c Added set_language_command and show_language_command to
|
||
implement the GDB support commands "set language" and
|
||
"show language".
|
||
expression.h A number of identifiers were added to the type exp_opcode
|
||
to facilitate Modula-2 builtin functions, integer
|
||
division, and array indexing.
|
||
|
||
Wed Jun 19 13:25:58 EDT 1991
|
||
|
||
language.h Added the macro STRICT_TYPE, which evaluates to non-zero
|
||
if the language specified by working_lang requires the use
|
||
of strict typing of expressions. Eventually, even this
|
||
will be able to be changed by the user.
|
||
Added the macro RANGE_CHECK, which evaluates to non-zero
|
||
if the language specified by working_lang requires the
|
||
checking of a value against the domain of its type.
|
||
Eventually, even this will be able to be changed by the
|
||
user.
|
||
language.[ch] Predicates involving types (simple_type, ordered_type,
|
||
same_type, integral_type, numeric_type, character_type,
|
||
boolean_type, float_type) are added. These predicates are
|
||
based on the current value of working_lang, and are handy
|
||
in type-checking.
|
||
|
||
Wed Jun 19 15:39:34 EDT 1991
|
||
|
||
eval.c Added the function type_array_rank which computes the rank
|
||
of an array type.
|
||
valarith.c Added the funtion value_bool, which when given a integer
|
||
value.h value (ie. struct value *) as an argument, it returns a
|
||
boolean value (ie. struct value *) true if that integer
|
||
is non-zero, and a boolean value false otherwise.
|
||
valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
|
||
will print out properly.
|
||
|
||
Wed Jun 19 16:36:34 EDT 1991
|
||
|
||
valops.c Added the function value_capitalize, which returns it
|
||
value.h argument capitalized if its argument is a lowercase
|
||
letter, or the argument unchanged if its argument is not a
|
||
letter.
|
||
valarith.c Added the function range_check_p, which returns non-zero
|
||
value.h if its value argument is between the integral bounds upper
|
||
and lower.
|
||
Added the function range_check_enum_p, which makes sure
|
||
that its value argument is a valid member of the domain of
|
||
its type argument.
|
||
Added the function range_check_range_p, which makes sure
|
||
its value argument lies between the upper and lower bounds
|
||
of its type argument, which must be a ranged type.
|
||
Added the function check_array_index, which range and type
|
||
checks an index of an array.
|
||
Added the function value_multi_subscript, which computes
|
||
array[idx1,idx2...idxN], given a value array and an array
|
||
of values representing indicies.
|
||
values.c Changed value_from_long to work with TYPE_CODE_CHAR and
|
||
unpack_long to work with TYPE_CODE_BOOL and
|
||
TYPE_CODE_CHAR.
|
||
|
||
Wed Jun 19 18:04:08 EDT 1991
|
||
|
||
symtab.c Stored pervasive types in a structure and make
|
||
lookup_pervasive_type() a lookup function that was based
|
||
on working_lang. If lookup_pervasive_type() returned
|
||
non-zero, then that value was returned (a fix, since
|
||
before it simply wouldn't return the pervasive type.)
|
||
language.h Added the macro CAST_IS_CONVERSION, which evaluates to
|
||
non-zero if the language specified by working_lang means
|
||
"conversion" when it says "cast".
|
||
valops.c Added the function value_real_cast(), which performs a
|
||
value.h *cast*, not a *conversion*, which is what value_cast()
|
||
does when it can. In particular,
|
||
value_cast(<float_type>,4) = 4.0, while
|
||
value_real_cast(<float_type>,4) = some mess.
|
||
eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
|
||
parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
|
||
expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
|
||
and MIN on integral types. *NOTE*: These are currently
|
||
hardcoded to work only if there are 8 bits per storage
|
||
unit. FIXME.
|
||
eval.c Made logical functions call value_bool to return a
|
||
properly typed boolean value, based on working_lang.
|
||
|
||
Thu Jun 20 11:55:27 EDT 1991
|
||
|
||
valprint.c Types now print out in a Modula-2 fashion. This works for
|
||
the cases when the type is printed out step-by-step, that
|
||
is, it doesn't work when the name of a structured type
|
||
(which includes the keyword "struct", etc.) is simply
|
||
displayed.
|
||
FIXME: Perhaps this is bad. Parts of it seem to kludgey,
|
||
since type specifications in C and Modula-2 are very
|
||
different. The C printing of a type is very recursive,
|
||
whereas in Modula-2 it is generally very simple. C has
|
||
type prefixes and suffixes, which have no real analogue in
|
||
Modula-2. Maybe type_print() should call a language
|
||
specific type printer. This is also advantageous if we
|
||
compile GDB to exclude some of the languages. We'll just
|
||
leave those functions out.
|
||
|
||
Thu Jun 20 16:57:10 EDT 1991
|
||
|
||
dbxread.c When reading the complete symbol table in (via
|
||
psymtab_to_symtab()), the number and types of function
|
||
arguments are added to a function type. define_symbol()
|
||
calls add_param_to_type() to accomplish this.
|
||
Assumption: when we come across a function definition
|
||
(N_FUN symbol with an 'f' or 'F' in the name), its
|
||
arguments will appear before another function definition.
|
||
When a function is found, a pointer to its type is placed
|
||
in the global in_function_type. Changes that
|
||
add_param_to_type() makes are to this global.
|
||
valprint.c The type of a function now includes (for Modula-2) the
|
||
types of its parameters.
|
||
eval.c Type checking and a check for the proper number of
|
||
arguments is now done for function calls. Not sure of the
|
||
impact this has on C++ member function yet.
|
||
|
||
Thu Jun 20 19:58:48 EDT 1991
|
||
|
||
valprint.c Rewrote the type printer. Broke it into two language
|
||
specific parts, adding the functions type_print_m2() and
|
||
type_print_m2_1().
|
||
An unfortunate consequence is this: if you debugging a C
|
||
program in Modula-2 mode (why?), info types does not work
|
||
well with regular expressions, since the types are printed
|
||
out in Modula-2 terminology, but stored in C terminology.
|
||
language.[ch] Added the functions new_type_last(), type_keyword(), and
|
||
type_sep() to aid in the printing of typedefs.
|
||
symtab.c Made the printing of typedefs as language independent as
|
||
possible through calls to new_type_last(), type_keyword(),
|
||
and type_sep().
|
||
|
||
Fri Jun 21 11:50:26 EDT 1991
|
||
|
||
dbxread.c Check all incoming ennumerated types. If it looks like
|
||
Modula-2's BOOLEAN type, then change the type_code of the
|
||
type to TYPE_CODE_BOOL so we can process it as a boolean
|
||
variable.
|
||
valprint.c Replaced some of the 0x%x with calls to sprintf and
|
||
hexformat() in val_print().
|
||
language.[ch] Added the function hex_to_string(), which converts its
|
||
integral argument to a hexadecimal number (format is
|
||
language based) and returns the result as a string.
|
||
|
||
Mon Jun 24 12:25:07 EDT 1991
|
||
|
||
valprint.c Some functions call type_print_1() directly, instead of
|
||
value.h using type_print(), so they can specify where (column) to
|
||
print things. Since type_print() takes care of language
|
||
dependence, that needs to be called first. Added a
|
||
parameter depth to type_print() (so it is now like
|
||
type_print_1). Changed type_print to type_print_at, and
|
||
made type_print a macro that passes a depth argument of
|
||
zero.
|
||
symmisc.c Changed all calls to type_print_1 to calls to
|
||
type_print_at.
|
||
Makefile.dist Made it possible to build GDB for a specific set of
|
||
depend languages. Do this by passing a definition for the macro
|
||
LANGS to make. LANGS should be a string containing a
|
||
space-separated list of language names (ie. LANGS="c m2").
|
||
The default is to build all languages. Note that grammar
|
||
files must follow the naming convention of <lang>-exp.y.
|
||
gdb.lang This holds the current value of the LANGS macro. It is
|
||
examined every time make is called, and is updated if
|
||
necessary.
|
||
eval.c Added #ifdef _LANG_<lang> to these files.
|
||
expread.c Still need to add them to dbxread.c and coffread.c.
|
||
main.c
|
||
source.c
|
||
symtab.c
|
||
utils.c
|
||
valarith.c
|
||
valprint.c
|
||
|
||
Mon Jun 24 16:33:11 EDT 1991
|
||
|
||
language.[ch] Added the functions hexformat_pre() and
|
||
hex_to_string_pre(), which take a prefix argument to
|
||
include in the format string. Thus, hexformat_pre("08") will
|
||
return "0x08x" (if the working language is language_c).
|
||
Made hexformat() and hex_to_string() calls to the above
|
||
with "" as the prefix argument.
|
||
|
||
am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
|
||
dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
|
||
infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
|
||
mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
|
||
pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
|
||
stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
|
||
valprint.c, vax-pinsn.c
|
||
|
||
Changed all occurences of 0x%[0-9]*l*x in printf format strings to
|
||
calls to hexformat() and hex_to_string(). Format strings without
|
||
the leading "0x" were ignored.
|
||
|
||
depend Updated to take the above into account.
|
||
|
||
|
||
Tue Jun 25 15:27:18 EDT 1991
|
||
|
||
symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
|
||
and type_check_t to keep track of the current state of
|
||
range and type checking.
|
||
main.c Added the variables range_mode, range_check, type_mode,
|
||
and type_check to record the current state of range and
|
||
type checking. Added initialization code to main().
|
||
language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
|
||
the above variables.
|
||
|
||
|
||
Tue Jun 25 17:57:08 EDT 1991
|
||
|
||
dbxread.c process_one_symbol() updates the variable (enum language)
|
||
source_lang based on the extension of the filename
|
||
contained in the N_SO sybmol that started this symtab.
|
||
When end_symtab() is called, the value of source_lang is
|
||
put into the language field.
|
||
stack.c select_frame() sets working_lang (and possibly type_check
|
||
and range_check) to the language field of the symtab
|
||
associated with the frame that is selected if working_mode
|
||
is language_auto. If working_mode is language_manual, a
|
||
warning is printed and working_lang is not set.
|
||
language.c Added the function set_type_range(), which sets the value of
|
||
type_check and range_check (if their modes call for
|
||
automatic setting) based on the current value of
|
||
working_lang. A non-zero argument will cause the current
|
||
settings to be output.
|
||
|
||
|
||
Wed Jun 26 14:51:40 EDT 1991
|
||
|
||
eval.c Added range checks on assignment.
|
||
m2-exp.y Added the grammar for sets to the language. Currently,
|
||
these do not do anything except print an error message.
|
||
|
||
Wed Jun 26 17:01:04 EDT 1991
|
||
|
||
m2-exp.y Added the ability for parse_number() to parse negative
|
||
numbers. A global flag is set upon encountering a unary
|
||
minus. This was done to make, for example, 1 parse as a
|
||
CARDINAL, and not as an integer, per Wirth's examples in
|
||
Programming in Modula-2 ed.4.
|
||
valprint.c Added support for "set radix 2" by then setting
|
||
output_format to 't'.
|
||
eval.c Implemented range checking on subrange types. Added calls
|
||
to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
|
||
Implemented MIN and MAX for ennumerated types. The
|
||
minimum value of an ennumerated type is defined by Wirth
|
||
as the first identifier, and the maximum as the last.
|
||
m2-exp.y Made octal numbers ending with "B" be characters and those
|
||
ending with "C" be numbers, per Wirth's book. (p. 34)
|
||
|
||
Thu Jun 27 14:11:52 EDT 1991
|
||
|
||
stack.c select_frame() now only sets working_lang, it does not
|
||
notify the user. If working_mode is language_manual, then
|
||
a warning is issued once.
|
||
main.c At the end of each call to execute_command(), working_lang
|
||
is checked against the local static (enum language)
|
||
current. If they differ and working_mode is
|
||
language_auto, the new settings of language, type and
|
||
range checking are printed out.
|
||
stack.c Modified frame_info() to include the language of the
|
||
current frame in the output of "info frame".
|
||
language.[ch] Added the function language_str() which returns the name
|
||
of the current language.
|
||
|
||
Fri Jun 28 15:33:14 EDT 1991
|
||
|
||
m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
|
||
the language. INCL and DECL currently cause an error,
|
||
since sets are not implemented yet. INC and DEC are
|
||
implemented as PREINCREMENT/PREDECREMENT with one
|
||
argument, and as ASSIGN_MODIFY with two arguments.
|
||
eval.c Added type checking to the above cases.
|
||
value.h Added not_lval_constant to the lval_type ennumerated type.
|
||
not_lval_constant means that the value is a constant
|
||
value; that is 3 or 'a' or TRUE, not as in a constant
|
||
identifier. This is used to help coerce numbers such as 3
|
||
to either signed or unsigned numbers.
|
||
valops.c Added the function value_coerce_constants() which coerces
|
||
constant integers as following: if one is a constant and
|
||
the other is not, the constant's type is set to the type
|
||
of the other argument. If both are constants and one is
|
||
signed, the other is converted to a signed constant.
|
||
|
||
Sat Jun 29 17:26:29 EDT 1991
|
||
|
||
valarith.c Added a better range checker. It now checks range
|
||
(successfully) on integral operations [+-] (signed and
|
||
unsigned) for any C sized type. Still does not work well
|
||
for multiplication.)
|
||
int_in_size() returns an integer that is coerced to fit into
|
||
specified number of bytes.
|
||
|
||
Mon Jul 1 13:04:14 EDT 1991
|
||
|
||
language.[ch] Added the function binop_result_type(), which returns the
|
||
builtin (struct type *) type that would be the result of a
|
||
binop on the two values V1 and V2.
|
||
|
||
Wed Jul 3 19:22:53 EDT 1991
|
||
|
||
source.c Extended source_info() to include the source language in
|
||
the output from "info source".
|
||
|
||
Fri Jul 5 13:48:52 EDT 1991
|
||
|
||
utils.c Moved the support functions for the GDB set/show commands
|
||
dealing with language into language.c.
|
||
language.c Added the function language_info(), which displays info
|
||
about the current working language, type and range check
|
||
settings. Called via the GDB command "info language".
|
||
Added an initialization routine _initialize_language(),
|
||
that sets defaults for the language, type and range
|
||
variables and sets up the new GDB commands.
|
||
main.c Language setup moved to language.c.
|
||
depend Rebuilt.
|
||
|
||
Mon Jul 8 10:10:22 EDT 1991
|
||
|
||
valarith.c Debugged the range checker for arithmetic. Still does not
|
||
work for multiplication very well.
|
||
|
||
Mon Jul 8 12:40:37 EDT 1991
|
||
|
||
language.[ch] Added the function value_true() which returns non-zero if
|
||
its argument represents a boolean true value.
|
||
breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
|
||
check the truth of an expression.
|
||
|
||
Thu Jul 11 12:51:34 EDT 1991
|
||
|
||
language.[ch] Added the predicate structured_type(), which returns
|
||
non-zero if the argument is a structured type.
|
||
Added the predicate pointer_type(), which returns non-zero
|
||
if the argument is a pointer type.
|
||
eval.c Added the ability to do addition and substraction on
|
||
pointers and integers. This case simply bypasses the
|
||
type checker.
|
||
|
||
Thu Jul 11 14:41:42 EDT 1991
|
||
|
||
include/stab.def
|
||
Added the symbol N_DEFD (0x4a) which is a definition
|
||
module dependency that is used by the GNU Modula-2
|
||
compiler and the linker. It is not important to GDB,
|
||
except that [dbx|coff|mips]read.c should ignore these
|
||
symbols.
|
||
|
||
Fri Jul 12 16:07:00 EDT 1991
|
||
|
||
valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
|
||
0 in val_print(). Also added statements to the else part
|
||
to coerce type (argument to val_print) to a pointer type
|
||
if it is an "array of unspecified length".
|
||
valops.c Added the function value_m2_string(), which returns a
|
||
(value) value which is a constant string, whose type is
|
||
(ARRAY [0..n] OF CHAR). The length field of the type
|
||
structure is set to zero, so it will be interpreted as an
|
||
"array of unspecified length".
|
||
stack.c Moved the language/frame mismatch check to
|
||
main.c:execute_command().
|
||
main.c The working language is recorded each time
|
||
execute_command() is executed. If working lang has
|
||
changed during its execution, then the new
|
||
language/type/range info is printed out for the user. If
|
||
the working language does not match the language of the
|
||
frame, a warning is issued.
|
||
|
||
Sat Jul 13 16:16:39 EDT 1991
|
||
|
||
eval.c Moved all the type-checking stuff for operators to
|
||
language.[ch] language.c. This is so we can keep language-specific
|
||
stuff (like for what type operators are defined) in
|
||
language.c.
|
||
language.[ch] Added the function binop_type_check(), which checks to see
|
||
if its two (value) arguments are type-compatible with its
|
||
opcode argument. The opcode should represent an operation
|
||
involving an operator. Also added the macro function
|
||
unop_type_check, which calls binop_type_check with a
|
||
NULL second argument.
|
||
expprint.c Added Modula-2 operators to the op_print_tab, so info
|
||
expression.h break works correctly. Also added "op_string", which
|
||
returns the string corresponding to the (enum exp_opcode)
|
||
opcode that is its argument.
|
||
|
||
|
||
Sat Jul 13 18:26:18 EDT 1991
|
||
|
||
coffread.c Added code to record the type of function arguments with
|
||
each paricular function. Code is very similar to that
|
||
added to dbxread.c.
|
||
dbxread.c Moved add_param_to_type() to symtab.c
|
||
symtab.[ch] Added function add_param_to_type() from dbxread.c
|
||
|
||
*** NOTE: The above additions have not been tested.
|
||
|
||
Mon Jul 15 12:50:47 EDT 1991
|
||
|
||
langauge.[ch] Added the functions type_error and range_error, which work
|
||
like error() except if the type/range mode is set to
|
||
*_mode_warn, then they do not do a return_to_top_level(),
|
||
but merely print a warning.
|
||
Also changed [set|show]_[type|range]_command() to support
|
||
the new "warn" feature.
|
||
|
||
Thu Jul 18 17:50:54 EDT 1991
|
||
|
||
mipsread.c Added code to record the type of function arguments with
|
||
each particular function. Code is very similar to that
|
||
added to dbxread.c.
|
||
|
||
*** NOTE: The above additions have not been tested.
|
||
|
||
Fri Jul 19 11:19:10 EDT 1991
|
||
|
||
defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
|
||
UMIN_OF_SIZE, which when given a size of a numeric type,
|
||
return the maximum and minimum value it can hold. UMAX...
|
||
and UMIN... return the result for unsigned types.
|
||
symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
|
||
struct types. They call above macros.
|
||
dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
|
||
avoid a name conlict with the above.
|
||
c-exp.y Added range checking on numeric constants in
|
||
parse_number() for completeness.
|
||
valarith.c Made binop_user_defined_p() and unop_user_defined_p()
|
||
return 0 if working_lang is not language_c.
|
||
|
||
Thu Aug 8 14:17:22 EDT 1991
|
||
|
||
main.c
|
||
printcmd.c
|
||
breakpoint.c Documentation strings of some commands changed to
|
||
eliminate the references to the C language where
|
||
appropriate.
|
||
|
||
Tue Aug 13 15:48:03 EDT 1991
|
||
|
||
m2-exp.y Added qualified identifiers to the grammar. The semantics
|
||
are slightly different from those of the GDB operator ::
|
||
c-exp.y
|
||
m2-exp.y Added a rule to each grammar of the form: start ::= exp |
|
||
type_exp, where type_exp is any valid type expression.
|
||
expression.h
|
||
eval.c Added the opcode OP_TYPE, and an error case in eval.c.
|
||
printcmd.c Modified ptype_command() so it actually parses the input
|
||
(necessary for type expressions with scope qualifiers).
|
||
Added the function ptype_eval() which expects an
|
||
expression composed of one OP_TYPE element.
|
||
*.[ch] Replaced all occurences of parse_c_expression with
|
||
parse_expression
|
||
*.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
|
||
|
||

Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
Small fixes from Peter Schauer:
|
||
|
||
* infrun.c (child_attach): Lint.
|
||
* solib.c (find_solib): Handle shared libs version 2.
|
||
|
||
Small fixes from David Wood:
|
||
|
||
* xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
|
||
|
||
Small fixes:
|
||
|
||
* remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
|
||
John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
|
||
|
||
* utils.c (wrap_here): Avoid wrap action of fputs_filtered if
|
||
chars_per_line is at maximum (user typed `set width 0'). Fix
|
||
from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
|
||
|
||
Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* coredep.c: include ptrace.h where necessary.
|
||
* mipsread.c(parse_lines): fix unsigned char problem that was
|
||
messing up line numbers on SGI's and possibly other MIPS based
|
||
platforms.
|
||
* infrun.c (child_create_inferior): use better test to check
|
||
return val from setpgrp().
|
||
* tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
|
||
for sgi/irix support.
|
||
|
||
Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mipsread.c (parse_symbol): Put non-static procedures
|
||
in the global block.
|
||
|
||
Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
|
||
|
||
Patch together `text_start' and `text_end' for 29K port.
|
||
|
||
* exec.c (exec_command): If NEED_TEXT_START_END, define the
|
||
variables and set them based on the exec file.
|
||
* am29k-tdep.c: declare text_start.
|
||
* valops.c (call_function_by_hand): declare text_end.
|
||
|
||
* inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
|
||
defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
|
||
because machines that do this will also have to know to
|
||
set NEED_TEXT_START_END. Besides, it was a redundant way to
|
||
say the same thing.
|
||
* tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
|
||
CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
|
||
NEED_TEXT_START_END.
|
||
|
||
Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
|
||
|
||
* Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
|
||
Pass MUNCH_DEFINE to munch whenever we run it.
|
||
* am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
|
||
format string; use 0x%x instead.
|
||
* am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
|
||
* ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
|
||
* xm-rtbsd.h: New host support for RT/PC running BSD Unix.
|
||
* inflow.c: Handle `short' process group IDs.
|
||
* infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
|
||
and check for ptrace errors.
|
||
* coffread.c (SDB_REG_TO_REGNUM): Define if not already.
|
||
(coff_symfile_init): Initialize text_bfd_scnum.
|
||
(read_coff_symtab): Use it to find the text [and absolute?] sections.
|
||
* ../config.sub: Add vendor nyu and os "sym[1-9]*".
|
||
* configure.in: Add hosts rtpc-*-* and a29k-*-*.
|
||
Merge target arm case with other "easy" cases. Add target
|
||
cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
|
||
Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
|
||
process).
|
||
* minimon.h, remote-adapt.c, remote-mm.c: Add.
|
||
* munch: Cope with RT/PC putting fns in data segment.
|
||
Restore ability to override `nm' by specifying MUNCH_NM.
|
||
* xconfig/rtbsd, xconfig/ultra3: New host systems.
|
||
* tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
|
||
and remote-adapt. Remove encapsulated coff #define's (the
|
||
support should go in BFD, and gdb shouldn't know or care).
|
||
* tconfig/a29k-kern: Same, but for remote kernel debugging.
|
||
* tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
|
||
* tm-29k.h: Update BADMAG (though it should go away).
|
||
Allow the register definitions to be overridden in another
|
||
tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
|
||
RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
|
||
DUMMY_SAVE_GR96, for handling kernel calling conventions
|
||
that use GR64+ rather than GR96+.
|
||
* tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
|
||
remote debugging of Ultra3 kernel. Includes tm-29k.h and
|
||
overrides various things.
|
||
|
||
* remote-mm.c (mm_attach, mm_wait): Handle attach like
|
||
child_attach does, making a clean stop in the newly attached
|
||
program.
|
||
* remote-eb.c: Lint.
|
||
|
||
* coffread.c: Make coffread independent of any particular
|
||
variant of COFF. Avoid #include-ing any particular one except
|
||
internalcoff.h. BFD now passes key values for symbol reading
|
||
as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
|
||
and the symbol masks and shifts); use them.
|
||
Remove obsolete end_of_text_addr.
|
||
|
||
* exec.c: Remove unused include files.
|
||
|
||
Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* Makefile.in (documentation targets): Pass $(M4).
|
||
Bugfix from eggert@twinsun.com (Paul Eggert).
|
||
|
||
* stack.c (down_silently_command): Check for stack existence.
|
||
|
||
Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* Makefile.in (VERSION): Update to 4.0.3.
|
||
|
||
Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* core.c (core_file_command): Print frame at coredump with
|
||
its level number, by calling print_stack_frame.
|
||
* frame.h: Add selected_frame_level, print_stack_frame.
|
||
* frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
|
||
* convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
|
||
Change print_sel_frame and print_selected_frame callers to
|
||
print_stack_frame.
|
||
|
||
* dbxread.c (read_ofile_symtab): Avoid empty else clause.
|
||
* symfile.c (free_named_symtabs): Ditto.
|
||
* main.c (main): wrap_here needs an arg.
|
||
* solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
|
||
(solib_add): Avoid noise.
|
||
(solib_create_inferior_hook): Lint.
|
||
(sharedlibrary_command): Move dont_repeat to here.
|
||
* utils.c (error): Call wrap_here to force buffered output.
|
||
|
||
Small patches from Peter Schauer:
|
||
|
||
* coffread.c (start_symtab): Free any existing line_vector before
|
||
malloc-ing new one.
|
||
(read_coff_symtab): Ditto for type_vector.
|
||
|
||
* source.c (lines_to_list): New variable, replacing function.
|
||
(all uses): Use as variable.
|
||
(_initialize_source): Add 'set listsize' and 'show listsize'.
|
||
* utils.c (lines_to_list): Remove function.
|
||
* stack.c (print_frame_info): Use as variable.
|
||
* defs.h (lines_to_list): Remove declaration.
|
||
|
||
Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* breakpoint.c (insert_breakpoints): Restore warning about
|
||
the program might be running in another process, but only for
|
||
systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
|
||
* xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
|
||
|
||
* utils.c (error): if error_pre_print is set, print the string
|
||
first.
|
||
* main.c (main, print_gnu_advertisement, print_gdb_version):
|
||
Reformat legalese so it always prints, but acts as an "I'm here"
|
||
message while symbols are being read. If any errors occur,
|
||
print a few newlines to set off the message and start it at the
|
||
left margin. Remove mention of "help" command, and don't yak
|
||
about symbol reading.
|
||
(catch_errors): Error string is now printed first in case of
|
||
error, not last.
|
||
* command.c (undef_cmd_error, lookup_cmd): On undefined command,
|
||
suggest the "help" command.
|
||
|
||
* Makefile.in (VERSION): Set to 4.0.2.
|
||
|
||
Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* .gdbinit: Remove useless "rr" command. Set complaints
|
||
to 1 for people debugging gdb.
|
||
|
||
* breakpoint.c, remote-vx.c: Reword strings printed by
|
||
catch_errors callers.
|
||
|
||
Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* WHATS.NEW: "history write -> history save". Doc "write on/off".
|
||
(Fix from kenc@viewlogic.com.)
|
||
|
||
Fix some infrastructure to be able to cope with host and target
|
||
machines with different sized basic types (ints, ptrs, etc).
|
||
(Idea from pierre@la.tce.com (Pierre Willard).)
|
||
|
||
* values.c (value_from_longest): Rename from value_from_long.
|
||
Handle pointer types as well as integers, so that targets with
|
||
different pointer sizes from the host can be accomodated.
|
||
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
|
||
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
|
||
uses of value_from_long to value_from_longest.
|
||
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
|
||
the correct pointer type to value_from_long{est}.
|
||
|
||
* doc/gdb.texinfo ($_, $__): Describe types of these variables.
|
||
|
||
* remote-vx.c: Remove obsolete code for calling functions via
|
||
vxworks kludge interface (it referenced value_from_long).
|
||
|
||
* valops.c (value_string): Find malloc with lookup_misc_func, not
|
||
raw search.

||
|
||
Make writing to files work properly. (Fixes to BFD are also needed.)
|
||
|
||
* core.c (core_open): Open file ourselves, read or r/w, depending on
|
||
write_files. Use bfd_fdopenr.
|
||
* gdbcore.h (write_files): New variable.
|
||
* exec.c (write_files): Define variable, add set&show for it.
|
||
(exec_file_command): Use write_files to open for read or r/write.
|
||
|
||
Make shared library reading happen automatically. These changes
|
||
are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
|
||
|
||
* inferior.h (stop_soon_quietly): Add to exported variables.
|
||
* infrun.c (child_create_inferior): call solib hook, if defined.
|
||
(child_attach): call solib hook, if defined.
|
||
* solib.c: Include inferior.h. Add from_tty to so_list as kludge.
|
||
(find_solib): Use lookup_misc_func rather than hand-rolled.
|
||
(symbol_add_stub): New stub for catch_errors.
|
||
(solib_add): Avoid output if !from_tty. Catch errors rather
|
||
than just calling symbol_file_add and bombing.
|
||
(solib_create_inferior_hook): Interface with the target process
|
||
to let it read and alloc shared libs, then figure out what it did.
|
||
|
||
* core.c (validate_files): Fix typo, soften warning.
|
||
(Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
|
||
|
||
* utils.c (fputs_demangled): Avoid duplicate printing if
|
||
demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
|
||
|
||
* infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
|
||
(Fix from pierre@la.tce.com (Pierre Willard).)
|
||
|
||
* main.c (catch_errors): Change argument to a char * from an int,
|
||
since a char * can point to a struct full of glop, but an int
|
||
is not guaranteed to be able to hold a pointer.
|
||
* breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
|
||
breakpoint_re_set_one, breakpoint_re_set): Adapt.
|
||
* core.c (core_open, solib_add_stub): Adapt.
|
||
* remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
|
||
|
||
Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
|
||
by adding .NOEXPORT target.
|
||
|
||
Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* GDB-4.0 release!
|
||
* Update README.
|
||
* Makefile.in (VERSION): Roll to 4.0.

|
||
|
||
Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
|
||
more on printsyms.
|
||
|
||
* doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
|
||
"gdb-all.texinfo"
|
||
|
||
* doc/rdl-apps.texi: renamed from rdl-apps.texinfo
|
||
|
||
* Makefile.in, doc/Makefile, doc/gdb.texinfo:
|
||
reflect above name change
|
||
|
||
* WHATS.NEW: correct pointer to refcard.
|
||
|
||
* doc/gdb.texinfo: update New Features, Installing
|
||
|
||
* doc/gdbint.texinfo: add short description of configure +template
|
||
|
||
Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/gdb.texinfo: update, fix bugs in "Installing" appendix
|
||
|
||
Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
|
||
tar file, add dependencies for referenced doc files.
|
||
|
||
Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
|
||
|
||
* coffread.c, symfile.c, stack.c: saberized.
|
||
|
||
Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/refcard.tex: permuted Essential Commands sec
|
||
|
||
* doc/gdb.texinfo: new C++ chapter; revised installation appendix;
|
||
new doc for
|
||
set/show symbol-reloading
|
||
default set complaints 0
|
||
info all-registers
|
||
RET-repeat disabled after prompted long displays
|
||
processID (attach) interpretation of 2nd GDB cmdline arg
|
||
|
||
Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
|
||
|
||
* expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
|
||
cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
|
||
breakpoint.c, main.c: lint.
|
||
|
||
Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Install new configuration scheme for GDB and friends.
|
||
|
||
* config.sub: Translate ordinary names to three-part names.
|
||
* configure: Use three-part names internally.
|
||
* configure.in: Translate three-part names to filenames.
|
||
|
||
* README, WHATS.NEW: Update for gdb-4.0.
|
||
* Makefile.in: Roll VERSION to 3.99.
|
||
|
||
Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
|
||
* i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
|
||
tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
|
||
to single structures rather than arrays; when passing
|
||
their address, use &. This avoids trouble with bdead compilers.
|
||
* mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
|
||
instead. This avoids portability headaches.
|
||
* mips-tdep.c (mips_do_registers_info): Only print FP regs if
|
||
asked to.
|
||
* source.c (open_source_file): Avoid ANSI const bdeath by
|
||
skipping declaration and then casting result value.
|
||
* tm-hp300bsd.h: Clarify comment.
|
||
* utils.c (strstr): Result is const char *; ANSI bdeath.
|
||
* xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
|
||
since system include file defines it differently from "defs.h",
|
||
though the two are equivalent for our purposes.
|
||
* tconfig/hp300bsd: Add m68k-tdep.o.
|
||
|
||
Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* tconfig/sun*4: Remove warnings about system assembler.
|
||
|
||
Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* mcheck.c: Avoid warning about undeclared abort fn.
|
||
* tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
|
||
it causes recursive calls to error() when used in cleanups.
|
||
To do so requires that we make it a function, so we do.
|
||
* sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
|
||
* utils.c (do_cleanups): Remove the current cleanup from the
|
||
chain *before* calling it, in case error() is called from it.
|
||
The result won't be pretty, but won't be an infinite loop either.
|
||
|
||
Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
|
||
|
||
* dbxread.c (read_struct_type): Grok anon structs for C++.
|
||
(vb_name, vptr_name): Null terminate these strings.
|
||
|
||
Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Minor bug fixes from BSD Net2 gdb:
|
||
|
||
* blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
|
||
returns 0, there is no previous frame.
|
||
* breakpoint.c (commands_command): If !from_tty, don't call
|
||
input_from_terminal_p().
|
||
* dbxread.c (record_misc_function): Speed up slightly.
|
||
(compare_psymbols): Ditto.
|
||
* infcmd.c (do_registers_info): Take a second argument to
|
||
determine whether to print float registers. "info registers"
|
||
does not do so anymore. "info all-registers" does, now.
|
||
* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
|
||
arg and ignore it.
|
||
* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
|
||
* inflow.c (initialize_inflow): Set tflags_ours correctly.
|
||
|
||
Other fixes:
|
||
|
||
* breakpoint.c (bpstat_do_actions): Use a cleanup to restore
|
||
executing_breakpoint_commands if we are interrupted by error.
|
||
* coffread.c (init_lineno): Avoid problem with zero-sized linetab
|
||
versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
|
||
* core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
|
||
catch_errors() so we can setup the frame regardless of whether
|
||
the shared libs work.
|
||
* ieee-float.c (double_to_ieee_extended): Get exponent from
|
||
right place in little-endian systems. From John Carey.
|
||
|
||
Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* main.c: Remove unused terminating_signals and catch_termination().
|
||
(long_options): Terminate with a zero element.
|
||
[Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
|
||
(gdb_readline): Make call-compatible with readline.
|
||
(init_signals): Improve comments re vfork vs. signal.
|
||
|
||
* utils.c (prompt_for_continue): Use new gdb_readline().
|
||
If we prompt for continuation, we don't let CR repeat the previous
|
||
command, once we get back to a prompt. It's too easy to keep
|
||
hitting CR, expecting "--more--" prompts, and have some long
|
||
command start repeating on you.
|
||
|
||
Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* blockframe.c (frameless_look_for_prologue): Speed up by
|
||
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
|
||
* tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
|
||
Define two variants, one faster.
|
||
* sparc-tdep.c (sparc_frame_chain): Use target_read_memory
|
||
and return zero, rather than giving an error.
|
||
(setup_arbitrary_frame): Initialize the PC in the new frame.
|
||
(skip_prologue): Add a second arg saying whether we're just
|
||
checking for a frameless function or not.
|
||
|
||
* core.c (core_open, core_close, core_xfer_memory): Move
|
||
section table pointers and bfd* into the target_ops.
|
||
(core_open): Allow errors in shared lib reading, etc.
|
||
(core_files_info): Describe shared library sections.
|
||
|
||
* exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
|
||
exec_files_info, set_section_command): Move section table
|
||
pointers and bfd* into the target_ops.
|
||
(add_to_section_table): Add BFD to section table.
|
||
|
||
* target.c (target_xfer_memory, target_info): Pass target to
|
||
xfer_memory and target_info functions.
|
||
* target.h: ''
|
||
|
||
* gdbcore.h: Move struct section_table.
|
||
* target.h: New home of struct section_table.
|
||
|
||
* solib.c (solib_add): New argument is the target_ops whose
|
||
section list is to be added to, if any. Reallocate the
|
||
sections in that target to add any that come from shared libs.
|
||
(throughout) so_sections renamed to sections.
|
||
(solib_xfer_memory): Deleted.
|
||
* tm-sunos.h (SOLIB_ADD): Add target argument.
|
||
(SOLIB_XFER_MEMORY): Delete.
|
||
|
||
* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
|
||
remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
|
||
from target_ops. It's the same on all targets. Add two section
|
||
pointers to target_ops.
|
||
|
||
* stack.c (find_relative_frame): Dump ancient algorithm for
|
||
"down", just use handy "next" pointers.
|
||
(frame_command): Don't error if there is no stack; let user
|
||
set one.
|
||
|
||
* inflow.c (new_tty_prefork, new_tty): New prefork routine
|
||
modifies static state in the parent process; new_tty itself
|
||
runs in the child and modifies the child's file descriptors
|
||
to match the saved static state.
|
||
* infrun.c (child_create_inferior): Call new_tty_prefork,
|
||
fork, then new_tty.
|
||
|
||
* infptrace.c (child_xfer_memory): Add ignored target arg.
|
||
* remote-eb.c (eb_xfer_inferior_memory): ''
|
||
* remote-nindy.c (nindy_xfer_inferior_memory): ''
|
||
* remote-vx.c (vx_xfer_memory): ''
|
||
* remote.c (remote_xfer_memory): ''. Rename from
|
||
remote_xfer_inferior_memory.
|
||
|
||
* main.c (main): Only try to attach "corefile" argument if
|
||
it starts with a digit.
|
||
|
||
* symfile.c (symbol_reloading): New "set/show" variable.
|
||
(symbol_file_add): Shorten message about symbol reading.
|
||
(add_symbol_file_command): Merge with add_syms_addr_command,
|
||
since this should work on all targets now.
|
||
(stop_whining): Default to zero, to shut up complaints
|
||
about bad symbol tables on many systems.
|
||
(free_named_symtabs): Just exit unless symbol_reloading.
|
||
|
||
* xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
|
||
and add comment explaining shared library screw.
|
||
|
||
* source.c: #if defined => #ifdef.
|
||
|
||
Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* doc/gdbint.texinfo: Improve doc on porting to new OS's.
|
||
|
||
Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/rdl-apps.texinfo: provide default readline-appendix finder
|
||
(doc/Makefile knows how to make one for local config)
|
||
|
||
* Makefile.in: use doc/Makefile for doc targets
|
||
|
||
* doc/Makefile: GDB documentation now has its own Makefile
|
||
doc/refcard.tex: renamed from "gdbrc.tex"
|
||
doc/gdbint.texinfo: add markup in "Cleanups" chapter
|
||
|
||
|
||
Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* values.c (baseclass_addr): When reading target memory, use the
|
||
length of the basetype, not the upper type. We've only malloc'd
|
||
enough space for the basetype, leading to errors in free().
|
||
|
||
* expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
|
||
ends up as a function specially, since we know the actual type of
|
||
the pointed-to address. This (somewhat) fixes display of
|
||
expressions that include misc_function_vector names. Try `cond 1
|
||
!strcmp("a","b")' then `i b'.
|
||
|
||
* infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
|
||
The child can be proceeded from inside wait_for_inferior in
|
||
evaluating breakpoint conditions, and DO_DEFERRED_STORES was
|
||
getting skipped in that case.
|
||
|
||
* expprint.c (print_subexp): Use filtered output, since the
|
||
subroutines we call use it, otherwise the output is horribly
|
||
mangled, since output of wrappable stuff comes out late.
|
||
|
||
* Makefile.in: Bump VERSION to 3.98.1
|
||
|
||
* infrun.c (child_create_process): Use execlp to find the
|
||
shell to exec our target program. This requires some fiddling
|
||
with `environ' since there is no execlpe().
|
||
|
||
Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
|
||
Minor rearrangement of refcard permits two new make targets--
|
||
gdbrc.dvi DVI output for refcard, using CM fonts
|
||
gdbrc.ps PostScript refcard, using PS fonts
|
||
|
||
Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* GDB-3.98 release.
|
||
|
||
* TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
|
||
* Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
|
||
|
||
Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/gdb.texinfo: last changes for release.
|
||
Minor typo and formatting fixes; incorporated most fixes remaining from
|
||
filed mail commenting on earlier drafts.
|
||
|
||
Added warnings: pipes don't work in run command;
|
||
conditions are converse of assertions;
|
||
step over fn without debug info goes to next fn;
|
||
vars may have "wrong" values near fn entrance, exit
|
||
|
||
Added example from Kingston on printing repeated nonadjacent values
|
||
|
||
Added explicit mention that in Emacs gdb mode C-c and C-z are like
|
||
shell mode for signals
|
||
|
||
Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
|
||
doesn't sound so much like its parent "Stopping and Continuing"; also
|
||
moved entries on continue to top of section, so they don't get lost.
|
||
|
||
Improved installation directions in appendix, added manual formatting
|
||
instructions
|
||
|
||
Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* configure.in: Remove xm.h and tm.h even if we aren't linking
|
||
new ones, so "./configure sun4; ./configure none" does the right
|
||
thing. Assume that alldeps.mak and depend are already built in
|
||
srcdir, and avoid running "make" (particularly "make depend",
|
||
which involves "gcc") from inside configure. Build Makefile
|
||
directly rather than building Makefile.conf first.
|
||
* configure: Regenerate with above changes.
|
||
* Makefile.in: Use $(BISON) to find bison. Roll VERSION
|
||
to 3.98. Revise gdb.tar.Z procedure to produce a file
|
||
called gdb-$(VERSION).tar.Z but which unpacks into a
|
||
directory called "gdb". Move non-source files out of
|
||
$(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
|
||
(depend): Don't try to do "gcc expread.y".
|
||
(expread.o): Update dependencies by hand.
|
||
|
||
Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/gdb.texinfo:
|
||
Fixed a variety of small typos that prevented info from formatting
|
||
cleanly; altered too-long heading for GPL Appendix, as discussed
|
||
w/RMS; Changed date on cover to July 91.
|
||
|
||
Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* doc/gdb.texinfo:
|
||
(1) Applied some fixes due to comments from Larry Breed (easier ones
|
||
through chapsec 5.2)
|
||
(2) Eliminated use of @footnote---had my doubts about it anyways, and
|
||
it's broken in latest texinfo
|
||
(3) Introduced *some* use of [] for optional arguments, where
|
||
explanation is not simpler by listing cmd w arg and cmd w/out arg
|
||
separately. Still not using @deffn.
|
||
(4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
|
||
couple of headings are too long. Need patches to texinfo or revision
|
||
to GPL-2.
|
||
|
||
* Partial update to README (which still needs work for this
|
||
release!): (1) use of configure corrected for new script,
|
||
(2) "make gdb.dvi" and "make gdb.info" mentioned.
|
||
|
||
Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* symtab.c (lookup_symbol): Don't complain right off about
|
||
no debug symbols; use the misc function vector first.
|
||
(list_symbols): Use misc function vector to find symbols
|
||
that don't have debug info, and print them.
|
||
(find_pc_symtab): Temporarily avoid fatal() when psymtab
|
||
PC range doesn't match symtab PC range, as it does on the
|
||
MIPS because our symtab reading isn't perfect.
|
||
|
||
* dbxread.c (dbx_symfile_read): Make warning about
|
||
"no debug symbols" slightly nicer.
|
||
|
||
* source.c (select_source_symtab): If "main" symbol exists,
|
||
but decode_line_spec can't find line info, don't just return
|
||
a zero; try other source symtabs or give an error.
|
||
|
||
* mipsread.c (parse_partial_symbols): Sort the psymtabs by
|
||
their low addresses first, then rip through fixing high addrs.
|
||
|
||
* ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
|
||
<runene@ifi.uio.no>.
|
||
(NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
|
||
|
||
Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* Minor, mostly mechanical, cleanup of doc subdir for clean
|
||
makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
|
||
and gdb.info (post- texinfo2 makeinfo) generated for distribution.
|
||
|
||
Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Mostly MIPS and general symbol-reading fixups.
|
||
|
||
* doc/gdbint.texinfo: Add documentation on symbol-reading
|
||
interface.
|
||
|
||
* mipsread.c: Remove kludges around #include "ecoff.h".
|
||
Remove redefinitions of a_magic, etc, no longer used.
|
||
(parse_symbol, ): Convert "Internal:" printfs to complain()ts.
|
||
Fix global overview comments to match symfile.c protocol.
|
||
(mipscoff_new_init): Eliminate cur_hdr if we have one.
|
||
(mipscoff_symfile_read): Eliminate unused code. Avoid
|
||
sorting all the symtabs, when all we have read here is psymtabs.
|
||
The symtabs are sorted as they are created anyway. Tell
|
||
condense_misc_bunches whether we're mainline.
|
||
(psymtab_to_symtab_1): Pass filename when recursing, to make
|
||
stack trace more informative.
|
||
(parse_partial_symbols): Assume cur_hdr as argument.
|
||
(read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
|
||
Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
|
||
the TYPE_NAME of char *, since that's done in symfile.c.
|
||
(free_numargs, parse_symbol, add_symbol, add_block,
|
||
shrink_linetable): Declare these fns void.
|
||
(upgrade_type): Convert tree of if's to switch. Clean up
|
||
bogus "off == 0" handling with a complaint. Avoid setting
|
||
field bitpos and bitsize of array with lower and upper bounds.
|
||
Check specified bitsize of elements against their actual type's
|
||
bitsize, and complain if different. Complain about unknown
|
||
type qualifiers.
|
||
(parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
|
||
(psymtab_to_symtab_1): Print names of subsidiary files that
|
||
are being read in. FIXME, we read far too many files. This code
|
||
is not the problem, the problem is in parse_fdr where the psymtabs
|
||
are set up.
|
||
(cross_ref): Result should indicate that we used one aux entry
|
||
normally, or two if we encountered a "next" entry. This used
|
||
to leave the caller pointing at the wrong aux entry.
|
||
(add_symbol): If overflowed cur_block, reallocate it larger,
|
||
chase all pointers to it, and complain(), rather than clobber memory.
|
||
(shrink_block): Use xrealloc rather than xmalloc-and-copy.
|
||
(new_field): Only allocate one field initially, not two.
|
||
Pull ++ out of macro argument. Simplify.
|
||
(_initialize_mipsread): Avoid initialization of importd
|
||
global_psymbols and static_psymbols.
|
||
|
||
* symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
|
||
to properly set pst->symtab; avoid searching for it.
|
||
(symfile_fns): Improve comments, add a FIXME.
|
||
* dbxread.c: Update comments to reflect symfile protocol.
|
||
(read_ofile_symtab, end_symtab): Return the symtab.
|
||
(psymtab_to_symtab_1): Set pst->symtab.
|
||
|
||
* coffread.c (coff_symfile_read): tell condense_misc_bunches
|
||
whether we're mainline.
|
||
|
||
* symfile.h (sym_fns): Remove unused sym_discard member.
|
||
* coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
|
||
|
||
* mtrace.c (mtrace): Take effect if mallwatch is set, even if
|
||
the environment variable is not.
|
||
* infcmd.c (finish_command): Use filtered printfs.
|
||
* cplus-dem.c: Add struct tags to a few unnamed structs.
|
||
* valops.c (value_coerce_array): Improve comments.
|
||
* valprint.c (type_print_varspec_suffix): Print array size only
|
||
if greater than zero.
|
||
* m88k-tdep.c: Shift some lines left by one space, that had
|
||
apparently been trashed at some point.
|
||
* TODO: More things to do, a few got done.
|
||
|
||
Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
|
||
(ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
|
||
comments.
|
||
* dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
|
||
* expread.y, findvar.c, symmisc.c: Ditto.
|
||
* printcmd.c (address_info): Update printed forms of LOC_
|
||
symbols. Elim LOC_EXTERNAL.
|
||
(print_frame_args): Keep track of param stack offsets before
|
||
re-looking up to find the local register param is kept in.
|
||
|
||
* mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
|
||
Further integration of mipsread into gdb. Eliminate unused
|
||
routines, duplicate declarations. Handle static symbols in
|
||
psymtabs as well as external symbols. When reading symtabs,
|
||
insert symbols into the correct block (global, static, or a local
|
||
block).
|
||
(read_mips_symtab, parse_partial_symbols): Don't pass useless
|
||
"incremental" arg.
|
||
(mipscoff_symfile_read): Don't call select_source_symtab.
|
||
(parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
|
||
rather than SYMBOL_VALUE.
|
||
(parse_external): Comment clobbering of top_stack.
|
||
(parse_partial_symbols): Update comments. Allocate and parse
|
||
static symbols as well as external symbols. FIXME, enum values
|
||
are not handled in this pass, but should be. Inline new_psymbol.
|
||
Use SYMBOL_VALUE_ADDRESS.
|
||
(psymtab_to_symtab_1): Read symbols into global static block
|
||
by default (until enter some function's local block context).
|
||
(sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
|
||
(destroy_all_symtabs, new_psymbol): Eliminate, unused.
|
||
|
||
* source.c (select_source_symtab): Select a source symtab
|
||
from either the symtabs or, failing that, the psymtabs.
|
||
(list_command): Update error message.
|
||
(forward_search_command, reverse_search_command): Use getc, not
|
||
fgetc, for speed. FIXME, add comment about buffers that die if
|
||
overrun by long line.
|
||
|
||
* values.c (unpack_field_as_long, modify_field): Avoid shifting
|
||
by an entire word, which is not portable, if we have a 32-bit
|
||
field. (Code in dbxread.c already turns such bitfields, if
|
||
aligned, into ordinary ints, but fixing this will help for other
|
||
symbol formats and for future changes.)
|
||
* core.c (core_open): Handle ANSI const brain death.
|
||
* utils.c (vprintf): Fix varargs typo.
|
||
|
||
Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* findvar.c (find_var_value): Handle &function better.
|
||
* TODO: Document work needed on &fn and &array.
|
||
* printcmd.c (print_address_symbolic): New arg is the prefix
|
||
to print if a name is printed.
|
||
(print_address_demangle): Honor "set print address" now.
|
||
Use new arg above to improve spacing of output.
|
||
* valprint.c (val_print): When printing function pointers,
|
||
print symbolic form too.
|
||
* breakpoint.c (breakpoint_1): Use new print_address_symbolic.
|
||
|
||
Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* core.c (memory_error): Reword error msg to mislead less.
|
||
|
||
* mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
|
||
|
||
* mipsread.c (read_mips_symtab, read_the_mips_symtab,
|
||
parse_partial_symbols): Use newer BFD internals (external_filehdr
|
||
and external_aouthdr), byte-swap the fields that we care about
|
||
before using them, and make the file header data local to
|
||
read_the_mips_symtab rather than global.
|
||
|
||
Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
|
||
from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
|
||
|
||
* main.c (command_line_input): Flush stdout and stderr
|
||
before every call to readline. This reportedly fixes a bug
|
||
that comes up in Sys V running emacs-gdb and/or xxgdb,
|
||
when stdin/out are pipes or sockets.
|
||
|
||
Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* configure.in, Makefile.in: Avoid rebuilding "depend" as much.
|
||
Avoid declaring Makefile dependencies, because GNU Make stupidly
|
||
tries to update it if we do.
|
||
|
||
* coffread.c: Revise for minor changes to bfd internal coff
|
||
indexes.
|
||
|
||
* configure: If -template= is given a relative path, make it
|
||
absolute before recurring in subdirectories.
|
||
|
||
* configure, configure.in, Makefile.in: Install "configure" script
|
||
as replacement for config.gdb.
|
||
* config.gdb, Makefile.dist, Makefile.sdir: Remove
|
||
* README: Update for configure, mostly. FIXME.
|
||
|
||
* Add dec3100 as equivalent to littlemips. Indicate in all host &
|
||
target config files that they are for the host. When the lines
|
||
get copied into the Makefile, this makes it more obvious what's
|
||
up.
|
||
|
||
Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* sparc-opcode.h (trap opcodes): Avoid leading spaces or
|
||
tabs, which end up in the disassembler output inadvertently.
|
||
|
||
Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Make it compile cleanly in an ANSI GCC2 environment.
|
||
|
||
* blockframe.c: <stdio.h>
|
||
* cplus-dem.c: free takes a void *, ifdef __STDC__
|
||
* dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
|
||
LONG_MAX/radix.
|
||
* defs.h (alloca): Avoid doing anything if alloca already def'd.
|
||
* stddef.h, stdlib.h: Remove these files.
|
||
* symtab.c: Avoid declaring qsort, close.
|
||
* symfile.c: Avoid declaring close.
|
||
* utils.c (vprintf): Declare "ap" arg as proper va_alist.
|
||
* sparc-tdep.c: Avoid including lots of Sun-host-specific files.
|
||
|
||
Assorted other changes.
|
||
* dbxread.c: include "libaout.h", not "liba.out.h".
|
||
* printcmd.c (print_frame_args): Set recurse properly for
|
||
indentation of struct and array parameters.
|
||
* valops.c (value_cast): Allow cast to void.
|
||
* infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
|
||
single_step() in a target-independent fashion.
|
||
* sparc-tdep.c (single_step): Don't call ptrace ourselves, just
|
||
set up to be ready to continue. This makes us target independent.
|
||
* infptrace.c (child_resume): Remove call to single_step; now
|
||
can single step a SPARC target of any kind.
|
||
|
||
Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
|
||
docn into separate sections---basically chapters, plus two loose
|
||
pieces that can be configured to go in different places. This
|
||
allows GNU m4 to preprocess the manual without coredumping.
|
||
|
||
* Makefile.dist: tell TeX where to find texinfo.
|
||
|
||
Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* Makefile.dist, doc/gdb.texinfo: respectively create, and use,
|
||
the new target "rdl-apps.texinfo" which captures the Makefile
|
||
variable that records where to find the Readline libraries.
|
||
|
||
Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
|
||
* tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
|
||
* defs.h (const, volatile): Only define if not already defined.
|
||
* Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
|
||
|
||
* README: Update for release 3.95.
|
||
* config.gdb: Don't create readline dir in subdir builds.
|
||
* main.c: Include with "..." form for non-system include files,
|
||
so "gcc -MM" for "make depend" works.
|
||
Include readline files with "...h" rather than <readline/...h>.
|
||
* mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
|
||
|
||
* coffread.c: Undo minor damage done by Rich Pixley. Use
|
||
different internal and external representations of COFF
|
||
data structures. Use new BFD routines for swapping them in and
|
||
out.
|
||
* symfile.c (free_named_symtabs): Avoid freeing file names that
|
||
are null or empty. Old i960 tools seem to produce files that
|
||
claim to have empty names, causing each successive file read
|
||
to blow away the previous one.
|
||
* sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
|
||
Move deferred_stores to top of file, but don't separate its
|
||
#define's from its variable. Add commentary.
|
||
* Makefile.dist: Fix Rich damage; undo "configure" changes in
|
||
favor of keeping the (working) config.gdb. Move readline
|
||
library up a notch.
|
||
|
||
Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
|
||
|
||
* dbxread.c (read_struct_type): Try to handle g++ version 1 MI
|
||
debug info.
|
||
* infptrace.c (fetch_registers): no result, since now void.
|
||
* tconfig/news: target depends on m68k-tdep too.
|
||
|
||
Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* Makefile.dist: added readline/inc-*.texinfo to dependencies for
|
||
gdb.dvi target
|
||
|
||
* readline/inc-history.texinfo, readline/inc-readline.texinfo:
|
||
applied various small fixes due to or inspired by RMS comments
|
||
|
||
* doc/gdb.texinfo: finished using all RMS comments, save those for
|
||
appendices on readline and cmd history (which are in other source
|
||
files)
|
||
|
||
Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
|
||
chapter 9; (2) documented 'break' command's menu mode for
|
||
overloaded names, in response to hgs problem report C++ p-31
|
||
|
||
Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* doc/gdb.texinfo: (1) better introductory example; (2) more
|
||
consistent use of @code, @samp, @file, @kbd throughout; small
|
||
cleanups to first three nodes; (3) new "Contributors" node;
|
||
(4) Appendix, Renamed Commands; (5) divert specialized startup
|
||
instructions to "Targets" chapter for generic manuals, while
|
||
leaving them up front for manuals specific to specialized
|
||
environments; (6) apply fixes from RMS comments through chapter 4.
|
||
|
||
* pretex.m4: modify explanatory text slightly (and redefine
|
||
"regexp") to keep GNU m4 from complaining. (It still crashes
|
||
later, but one step at a time...)
|
||
|
||
Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* readline/readline.c (update_line): Avoid dereferencing a pointer
|
||
before comparing it to its bounds. Saber caught this.
|
||
(init_terminal_io): Don't set BC from the "pc=" termcap variable,
|
||
and only set PC if tgetstr returned non-null. Saber caught this.
|
||
|
||
Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
|
||
stuff for config manual) here where it counts; updated
|
||
to use new subdir structure (gdb/doc/).
|
||
|
||
* Makefile: generated from above via
|
||
config.gdb none
|
||
before checkin
|
||
|
||
* gdbint.texinfo: added instructions on generating gdb.info* files
|
||
locally for release. These are ordinary info
|
||
files, formatted from gdb.texinfo (via gdb-all.texinfo, see
|
||
Makefile)---but due to use of texinfo 2, can't count on makeinfo
|
||
to generate these, so we distribute them already formatted.
|
||
|
||
* gdb.texinfo: included full Info node and menu crud (as generated
|
||
by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
|
||
|
||
* Makefile: updated "gdb.dvi" target to use M4 preprocessor;
|
||
put in comments-for-future gdb.info target (one day makeinfo will
|
||
work again).
|
||
|
||
Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* gdb.texinfo: Updated to include new or old undocumented
|
||
commands, at least the following (perhaps some others I forgot to
|
||
record): info f, info float, info path, info program, info s, info
|
||
set, info source, info terminal, info types, info user, set/show
|
||
print object.
|
||
Also covered all recent GDB command renames for v4.
|
||
|
||
Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* mipsread.c: Rather than keeping count of how many symtabs
|
||
and psymtabs we have, for sorting purposes, count them when
|
||
we need to sort. This fixes bug in rereading of symbol tables.
|
||
|
||
Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
|
||
|
||
* infcmd.c: renamed "info path" to "show paths"
|
||
* gdbrc.tex: documented above.
|
||
|
||
Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* remote.c: Fix comments.
|
||
* utils.c (error): Force out any pending wrap output.
|
||
|
||
Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* Makefile.dist: Roll VERSION to 3.95.
|
||
Fix up "saber_gdb" to work again.
|
||
* saber.suppress: Update.
|
||
|
||
* coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
|
||
symtab.h, target.c, target.h: Lint.
|
||
* core.c: setup and select frame after reading shared libs,
|
||
else reading shared libs will clobber them. Lint.
|
||
* utils.c (error): Force out any buffered wrap text.
|
||
|
||
Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* remote.c: Remove decls of memory_insert_breakpoint
|
||
and memory_remove_breakpoint, no longer used. (Suggestion of
|
||
Jan Norden).
|
||
|
||
* Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
|
||
to make it easier to interface to "configure"'d libraries.
|
||
|
||
Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
|
||
|
||
* valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
|
||
aliases for set/show print.
|
||
|
||
Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
|
||
|
||
* coffread.c (coff_sym_fns) [TDESC]: Make the type be m88kbcs.
|
||
|
||
* m88k-tdep.c (IEEE_isNAN): New function.
|
||
|
||
* infrun.c, m88k-tdep.c, m88k-xdep.c: Change
|
||
initialize_{tdesc,dcontext} to init_{tdesc,dcontext}.
|
||
|
||
* infrun.c [TDESC]: Add a bunch of crud.
|
||
|
||
* xm-88k.h [__GNUC__]: Don't define memset.
|
||
|
||
* m88k-xdep.c: #if 0 out push_breakpoint.
|
||
|
||
* tm-88k.h: Define GET_SAVED_REGISTER.
|
||
|
||
* tm-88k.h: Define DGUX.
|
||
|
||
* m88k-opcode.h (UEXT, SEXT, MAKE): Put parentheses around arguments.
|
||
|
||
* m88k-pinsn.c (sprint_address): Declare at top of file.
|
||
|
||
* m88k-xdep.c: #if 0 out core_file_command.
|
||
|
||
* values.c ({unpack_,value_as_}pointer): Just call
|
||
{unpack_,value_as_}long (for now anyway).
|
||
|
||
* m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().
|
||
(psr_register): Change return type to dc_word_t.
|
||

before we compile it.
|

||
param.h: Include defs.h.
|
||
signame.c: Change #ifdef SYS_SIGLIST_MISSING to #if.

|
||
New function to give correct error message.
|

Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
|
||
|

|
||
(_initialize_symfile, add_syms_addr_command):
|
||
Rename add-syms to add-symbol-file.
|
||
|
||
Thu Apr 18 18:08:30 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* symfile.h (free_named_symtabs): Rename from free_named_symtab.
|
||
* symfile.c (clear_symtab_users_once, cashier_psymtab,
|
||
free_named_symtabs): Move these routines from symmisc.c.
|
||
* symmisc.c (same): same.
|
||
(free_symtab): Make non-static.
|
||
* symtab.h (free_symtab): Declare as exported void fn now.
|
||

|
||
|
||
Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Permit symbols to be superseded when new symbol files have
|
||
been read in, particularly for VxWorks.
|
||
|
||
* dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
|
||
to the main file, as well as to include files. Also, put global
|
||
functions into the global psymtab, to make "i fun" work.
|
||
(end_psymtab): Free named symtabs and psymtabs for a file, once a
|
||
new psymtab for it has been read.
|
||
* coffread.c (end_psymtab): Free named symtabs and psymtabs for
|
||
a file, once a new symtab has been read for it.
|
||
* mipsread.c: FIXME. We need to do the same for MIPS, but it
|
||
looks harder to determine the top-level block before it's been
|
||
queued to the psymtab list.
|
||
|
||
* symfile.c (symbol_file_add): Use filtered printing and wrap it.
|
||
If we have wiped out any old symbol tables, clean up at end of
|
||
symbol reading.
|
||
(symbol_file_command): Don't reference symfile_fns if it's zero.
|
||
|
||
* symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
|
||
defines for the blocks of a blockvector that contain global and
|
||
file-static symbols and the first of the smaller scope contours.
|
||
* symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
|
||
decode_line_1, make_symbol_completion_list): Use the above.
|
||
* coffread.c (end_symtab, patch_opaque_types): Ditto.

||
* dbxread.c (end_symtab): Ditto.
|
||
* expread.y (block): Ditto.
|
||
* mipsread.c (throughout): Ditto.
|
||
* symmisc.c (free_named_symtabs): Ditto.
|
||
|
||
* symtab.c (list_symbols): Process the first symbol of the
|
||
static psymbols list.
|
||
(types_info): Restore this function from its untimely #if 0.
|
||
It's not perfect, but it is better than nothing.
|
||
(_initialize_symtab): Restore "info types".
|
||
|
||
Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* m68k-stub.c: Remote stub for 680x0's, created from
|
||
rem-m68k.shar (which is removed).
|
||
* nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
|
||
Remove RCS log stuff now that we use CVS and it blows our diffs.
|
||
|
||
Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* symmisc.c (free_named_symtab): Make it work, in its current
|
||
kludgy fashion. Change result to indicate if we blew away bkpts.
|
||
* dbxread.c (end_symtab): Accumulate result from
|
||
free_named_symtab and print warning if we blew user's state.
|
||
* symfile.h: free_named_symtab now returns an int.
|
||
|
||
Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* dbxread.c (dbx_symfile_read): Initialize psymbol list if this
|
||
is the first symbol read, even if not mainline.
|
||
(dbx_psymtab_to_symtab): symfile might be zero, cope.
|
||
* exec.c (exec_ops): Add_syms_addr is valid in our tvec.
|
||
(set_section_command): New command ("section xxx yyy" -- should
|
||
be renamed to "set section xxx yyy" FIXME) which sets the
|
||
base address of a section of the exec file, overriding the
|
||
virtual address that BFD reports.
|
||
|
||
Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* exec.c: Add add_syms_addr_command to exec_ops, so you can
|
||
load symbols at any address while examining an exec file.
|
||
|
||
Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* tm-i386v.h (FLOAT_INFO): Don't define it, since the code
|
||
for printing the float info is host-dependent, not
|
||
target-dependent. FIXME.
|
||
* i386-pinsn.c: Move #includes to top, remove useless ones.
|
||
* i386-tdep.c: Don't bother including <.../reg.h> since we
|
||
don't use it (and it doesn't exist on host systems).
|
||
|
||
* ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
|
||
Convert negative numbers properly.
|
||
(ieee_test): Make numbers really random; fix format arg.
|
||
|
||
* infcmd.c (attach_command, detach_command): Don't repeat on CR.
|
||
* core.c (core_detach): Unpush core_ops, which might not be on
|
||
top. We used to just pop the top, which broke things. Don't
|
||
need dont_repeat() any more.
|
||
(core_file_command): Psst! Don't repeat it.
|
||
* remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
|
||
* expprint.c (print_subexp): Avoid switch fallthru on
|
||
BINOP_ASSIGN_MODIFY, so we can print += and such.
|
||
* frame.h: Fix typo.
|
||
* inflow.c (kill_command): After killing inferior, print our
|
||
current frame in the core file, if we have one.
|
||
(generic_mourn_inferior): When inferior dies, either select
|
||
the current frame (in the new target, e.g. core file), or
|
||
set both the current and selected frames to NULL.
|
||
|
||
Changes from Peter Schauer.
|
||
|
||
* infptrace.c: Avoid <sys/ptrace.h> on USG.
|
||
|
||
* Make all file names fit in 14 characters (sigh and damn!):
|
||
mv hp300hpux-xdep.c hp300ux-xdep.c
|
||
mv symmetry-xdep.c symm-xdep.c

mv symmetry-tdep.c symm-tdep.c

|
||
* Makefile.dist, README, config.gdb, convex-pinsn.c,
|
||
tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
|
||
xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
|
||
names.
|
||
|
||
* command.c (user_info_1, user_info): New command for listing
|
||
the user-defined commands.
|
||
|
||
Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* dbxread.c (really_free_pendings): Clear file_symbols
|
||
and global_symbols after freeing them; otherwise, running
|
||
this function twice (if it appears twice on the cleanup
|
||
chain), we try to free things twice.
|
||
|
||
* dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
|
||
based on text_addr (the address of text in core), not on addr (the
|
||
offset between text in the .o file and in core). This change
|
||
is from Peter Schauer.
|
||
|
||
* main.c: Define ALL_CLEANUPS as a cast of zero.
|
||
(return_to_top_level): Use it.
|
||
(main): Do all cleanups after each command run as part
|
||
of the gdb startup sequence. Also do all cleanups before
|
||
entering the command loop, and every time we exit the command
|
||
loop and reenter. Before, the cleanups from the startup sequence
|
||
were being left undone until the first error!
|
||
(command_loop): Rename do_nothing cleanup to command_loop_marker
|
||
so we can see it easily when examining the cleanup chain.
|
||
(init_signals): Add another do_nothing for signal handling.
|
||
(quit_command): Only try to kill target if it has execution.
|
||
Problems in the target stack got us into a state where
|
||
inferior_pid was nonzero but none of the targets had execution.
|
||
In this state you couldn't exit gdb.
|
||
|
||
* dbxread.c: Two changes from Peter Schauer.
|
||
(echo_command): Fflush output after an echo command.
|
||
(show_history): Pass all args to cmd_show_list.
|
||
|
||
* utils.c (init_malloc): Call mtrace to turn on tracing
|
||
if the environment variable MALLOC_TRACE is set to a file name.
|
||
* mtrace.c: Add source file which provides a log of every malloc,
|
||
free, and realloc to a trace file.
|
||
* mtrace.awk: Add source file which analyzes the trace file.
|
||
* Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
|
||
(VERSION): Roll to 3.94.3.
|
||
|
||
* breakpoint.c (breakpoint_1): Add a space to "i watch" output.
|
||
(check_duplicates): Don't bother with watchpoints.
|
||
(set_raw_breakpoint): Comment about danger of this routine.
|
||
(watch_command): Parse and eval all args before calling
|
||
set_raw_breakpoint.
|
||
|
||
* solib.c (find_solib): Avoid error in referencing memory to
|
||
see if any more shared libraries have been added. This is
|
||
particularly useful if the target has terminated. Bug reported
|
||
by Peter Schauer.
|
||
|
||
Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
|
||
in bringing up 3.94.2 on the Sun-3.
|
||
|
||
* Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
|
||
* breakpoint.c (enable_breakpoint): Check for valid watchpoint
|
||
expression (in scope) before reenabling watchpoint.
|
||
* signame.c (init_sigs): Add missing declaration of i, fix
|
||
sys_siglist declaration.
|
||
* source.c (list_command): Fixed range computation to use
|
||
lines_to_list ().
|
||
* stack.c (backtrace_command): Do not allow command if target has
|
||
no stack, print informative error message.
|
||
* target.c (target_command): Do not write into command line
|
||
because this fails if the target command is used in a user defined
|
||
command. [This change was enhanced by gnu to support any-
|
||
unique-prefix matching on target names.]
|
||
* valops.c (value_struct_elt): Avoid infinite loop on an
|
||
erroneous attempt to print the member of function (try p main.p).
|
||
|
||
Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* expread.y (name_no_typename): Avoid reduce/reduce errors
|
||
caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
|
||
Since the GDB parser really doesn't use name_no_typename in a
|
||
name-only context, the parser can't tell the diff between
|
||
names and numbers here. Avoid allowing a name_no_typename
|
||
to be a NAME_OR_*INT to resolve the conflict.
|
||
|
||
Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
|
||
|
||
* valprint.c (val_print_fields): bitfield printing didn't handle
|
||
byte order. Indirect through a few more fns to cope.
|
||
|
||
* values.c (modify_field): also cope with byte order.
|
||
|
||
Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Cleanup for release 3.94.2:
|
||
|
||
* Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
|
||
include files. Roll version to 3.94.2.
|
||
|
||
* coffread.c (init_stringtab): Read length into unsigned char
|
||
array before swapping; don't assume 32-bit longs.
|
||
|
||
* target.c (target_info): Don't bother with get_sym_file, just use
|
||
the symfile global variable.
|
||
* symtab.h, symfile.c (get_sym_file): Delete it.
|
||
|
||
* dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
|
||
(define_symbol): Set symbol line number to 0 if not gcc-compiled.
|
||
(read_type): Replace one more error() with complain().
|
||
|
||
* mipsread.c (parse_partial_symbols): Replace printf with complain.
|
||
|
||
* i960-tdep.c: Fix copyright attribution.
|
||
|
||
* config.gdb: Quote all backquotes in doublequotes. You can
|
||
quote me on that. BSD 4.4 shell found this one.
|
||
|
||
* infptrace.c (throughout): The third argument to ptrace is an
|
||
int *, not an int.
|
||
|
||
* infrun.c (wait_for_inferior): When program has terminated, we
|
||
have to call target_terminal_ours before we pop that target off
|
||
the stack (e.g. before a call to target_kill or
|
||
target_mourn_inferior). This fixes problem where a program
|
||
terminates, then GDB stops for (tty output) and you have to type
|
||
"fg" to the shell to resume it. FIXME: This code for what to
|
||
do after termination really should be in normal_stop instead.
|
||
|
||
* gdbcore.h (read_memory_check): Change declaration; it changed
|
||
names months ago.
|
||
|
||
* terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
|
||
4.4 prereleases, this avoids a bug in their sgtty compatability
|
||
support.
|
||
* remote.c: Use terminal.h rather than hand-rolling the same.
|
||
|
||
* signame.c, signame.h (psignal): Arg is unsigned, not int.
|
||
* utils.c (strsave, strstr): Fix arg types.
|
||
* valprint.c (val_print): lint
|
||
|
||
MIPS symbol table support from Per Bothner:
|
||
|
||
* symfile.c (symtab_fns): Remove initializer table that needs to
|
||
be hacked for each new symbol file format supported.
|
||
(add_symtab_fns): New function, chains symbol table
|
||
handlers into the global list.
|
||
(symfile_init): Search this list.
|
||
* symfile.h: Add next pointer, declare add_symtab_fns.
|
||
* coffread.c (_initialize_coffread): Call add_symtab_fns.
|
||
* dbxread.c (_initialize_dbxread): Call add_symtab_fns.
|
||
|
||
* mipsread.c (psymtab_to_symtab_1): return void instead of (struct
|
||
symbol *). Thus, we no longer need the hack to trash
|
||
pst->filename. Good, since that hack confused code in symfile.c!
|
||
|
||
(reorder_symtabs, destroy_all_symtabs): Removed static
|
||
all_symtabs, which was used to qsort symtabs in reorder_symtabs.
|
||
Instead, the latter now uses a temporary array (stack-allocated
|
||
from an obstack, and then freed).
|
||
|
||
(parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
|
||
haven't been set in the outermost stBlock of a procedure. This was
|
||
a problem with f77 binaries on Ultrix 4.?.
|
||
|
||
(new_symtab, new_symbol, new_type): Continue changing code to use
|
||
obstacks more and otherwise conform to dbxread internal style.
|
||
Made the free_code of symtabs be free_linetable (as in dbxread)
|
||
instead of free_contents. This implies memory leaks when reading
|
||
a new symbol table, until the conversion is finished. Did change
|
||
(struct symbol) and (struct type) to be allocated on the
|
||
symbol_obstack. Blocks and blockvectors are among the things
|
||
still "leaking."
|
||
|
||
* mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
|
||
tested much, but it solved one problem (reported by Meissner), and
|
||
cleans up some other things. The problem happened when an
|
||
included file contains actual code (functions) and not just
|
||
definitions. The mips coff is a little inconvenient there, since
|
||
it may cause a procedure to be mapped to the wrong psymtab.
|
||
|
||
* mips-tdep.c (heuristic_proc_desc): Minor cleanup.
|
||
* mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
|
||
this will need work for the new core paradigm.
|
||
|
||
Opcode patches from the net:
|
||
|
||
* mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
|
||
ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
|
||
missing altogether - they are added here. From Bruce Bauman.
|
||
* mips-opcode.h: The low mask for C0 instructions was too small.
|
||
From Garrett Lau. I modified the fix to check the entire 32-bit
|
||
opcode.
|
||
|
||
* ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
|
||
Bauman.

|
||
|
||
Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
|
||
|
||
* dbxread.c (read_type): Pointer subtraction (value_sub in
|
||
valarith.c) sometimes failed because the types of the
|
||
pointers being subtracted were not identical.
|
||
These differed because dbxread.c was allocating pointer types
|
||
using dbx_alloc_type+smash_to_pointer_type instead of
|
||
lookup_pointer_type. I failed to find a justification for the
|
||
former, so I changed it to use the latter. Similarly, I
|
||
replaced smash_to_function_type by lookup_function_type,
|
||
and smash_to_reference_type by lookup_reference_type.
|
||
|
||
* mipsread.c (parse_symbol, upgrade_type, parse_procedure,
|
||
_initialize_mipsread): corresponding changes.
|
||
|
||
* symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
|
||
|
||
* source.c (mod_path): Do tilde_expand on each component of the path,
|
||
rather than on the (list of) paths as a whole.
|
||
(print_source_lines): Set first_line_listed in addition to
|
||
current_source_symtab and current_source_line. If the source was
|
||
not findable, after a "dir" command to fix the problem,
|
||
a "list" would get the wrong lines.
|
||
|
||
While I was there... (gnu):
|
||
|
||
* dbxread.c (read_type): Change error to complaint.
|
||
|
||
Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
First attempt at detailed understanding of symbol table memory alloc.
|
||
|
||
* dbxread.c (dbx_symfile_read): Free our string table if we
|
||
aren't the mainline. Free the "info" struct since we're done with
|
||
it.
|
||
(init_psymbol_list): Free any previously allocated psymbol lists.
|
||
(): FIXME: Should realloc-down the psymbol lists when done reading
|
||
the main symbol file?
|
||
|
||
* symmisc.c (free_symtab): Free fullname field too.
|
||
|
||
* xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
|
||
(REGISTER_ADDR): Make result type unsigned int.
|
||
|
||
* xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
|
||
define REGEX must also define REGEX1 (its dependency).
|
||

|
||
in addition to the child's. PATH, G960BASE, G960BIN for starters.
|
||
* source.c (mod_path): New function, from guts of
|
||
directory_command, modifies a path. Used by path_command.
|

|
||
(_initialize_utils): "set screen-width" => "set width";
|
||
"set screen-height" => "set height"; add sevenbit-strings.
|
||
|
||
* infcmd.c (do_registers_info): Print floating point registers
|
||
in raw hex as well as float format, regardless of whether it is
|
||
a "virtual" convertible register.
|
||
* tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
|
||
regs as a double, just in case it's being used that way.
|
||
* values.c (unpack_long): Comment on array/function coercion.
|

|
||
* remote-nindy.c: Use ieee-float stuff.

|
||
to extended.
|
||
(nindy_store_registers): Pack extendeds to host double, flip
|
||
around by misusing unpack_double, send as target double.
|
||
|
||
* tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
|
||
zero, as when stopped at the first instruction of a process.
|
||
|
||
* blockframe.c: Fix filename in comment (param.h => tm.h).
|
||
* sparc-tdep.c (skip_prologue): More explicit nudging comments.
|
||
* tm-68k.h: Fix typos.

|
||
|
||

|
||
|
||
* coredep.c (fetch_core_registers): Pass end-address of register
|
||
section to register_addr as expected. Don't call supply_register
|
||
if we'd just pass it garbage.
|
||
|
||
* dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
|
||

||
|
||

|
||
|
||
Clean up IEEE floating point support.
|

|
||
* dbxread.c: Remove static symfile_bfd.
|
||
* infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
|
||
it is not used yet.
|
||
* inftarg.c (child_detach): Pop the child_ops vector if the
|
||
detach is successful.
|
||
* remote-nindy.c (nindy_create_inferior): Don't push a new
|
||
nindy_ops since nindy uses the same one for execution and memory
|
||
examination anyway.
|
||
* core.c (core_ops): Use child_attach and child_create_inferior
|
||
rather than default attach and create_inferior functions.

||
Handle floating point registers in core files.
|
||
|
||
* sparc-xdep.c (fetch_core_registers): Rewrite for float support.
|
||
* sun3-xdep.c (fetch_core_registers): Rewrite for float support.
|
||
This version untested since BFD doesn't yet support sun3 core
|
||
files.
|
||
* hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
|

conventions. Fix comments and style. This version has not
|
||
been compiled yet, since we have no HP inhouse.

|
||
and ".reg2", and pass both to fetch_core_registers sequentially.
|

||
|
||
* source.c (forget_cached_source_info): Not static any more.
|
||
(init_source_path): New default source path is "$cdir:$cwd".
|
||
(dir_command): Handle variable arguments ($cdir, $cwd).

|
||
"Originally compiled in" to remind people of $cdir.
|
||

|
||
(open_source_file): If compilation directory is known, replace
|
||
first $cdir in path with the compilation directory.
|
||
(print_source_lines): Even if we can't print the lines, set the
|
||
current symtab and line for future commands like "info source" or
|
||
"breakpoint". Also, error message now contains the file name,
|
||
line number, and file access error message.
|
||
(_initialize_source): Fix help text to describe changes.
|
||
* main.c (cd_command): Forget cached source info when we chdir.
|
||
* utils.c (strstr): Add simple implementation.

* coffread.c (read_one_sym, init_linetable, init_stringtab):
|
||
Byte-swap COFF symbol tables if necessary when reading them in.

|
||
symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
|
||
declarations of errno.
|
||
|
||
* remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
|
||
|
||
* remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
|
||
<rpc/rpc.h> and <rpc/types.h>.
|
||
|
||
Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* i960-tdep.c (examine_prologue): Add new argument limit,
|
||
which stops the scan at the end of the prologue, or at the PC.
|
||
This fixes a problem where it walks down into the code for the
|
||
user's statements if that code looks like function prologues.
|
||
Mark Fox and I have been bouncing this code back and forth, making
|
||
small changes to it. Callers changed to match.
|
||
|
||
Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
|

||
Cleanup for gdb-3.94 release final:

|
||
* Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all

|
||
|
||
* am29k-tdep.c: Add contribution line.
|
||

|
||
|
||

|
||
Update target_ops vector to add attach, close, and load entries.

add_file. Break out close routine from existing code.
|

|
||
Lint.
|
||

|
||
|
||
* exec.c (exec_close): New function.

|
||
Fix byte order of frame pointer.
|
||
(read_var_value): Result of 0 if var's value can't be found,
|
||
e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
|
||
LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
|
||
(locate_var_value): Use read_var_value and use its lazy address
|
||
as the location of the var's value. Lint.
|
||
|
||
* i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
|
||
instructions.
|
||
|
||
* i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
|
||
obsolete Intel versions in favor of vxgdb versions.
|
||
(check_host, byteswap, byteswap_val, reorder_val): Eliminate

|
||
order rather than gdb-4's target byte order.
|
||
(i960_frame_chain_valid): Move to nindy-tdep.c.
|
||
(examine_prologue, skip_prologue, frame_find_saved_regs,

frame_args_address, leafproc_return, saved_pc_after_call,
|
||
pop_frame): Add vxgdb versions from Mark Fox.

Cache result in the frame info to avoid performance hair in
|
||
callers.

(print_fault): Add gdb960 code for printing faults.
|
||
(_initialize_i960): Actually call check_host.
|
||
|
||
* ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):

set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
|
||
findvar.c to here, since it depends on the contents of the
|
||
shadow_contents of breakpoints, but keep if #if 0 since it is
|
||
never called.
|
||
|
||
* nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
|
||
from i960-tdep.c.

target_has_execution.
|
||
(print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
|
||
code for actually finding the values of arguments, though we still
|
||
keep track of the maximum stack offset for use in printing unnamed
|

arguments. Handle missing FRAME_ARGS_ADDRESS.
|
||
|
||
* remote-nindy.c (i960_print_fault): Move to i960-tdep.c.

|
||
(nindy_fetch_registers, nindy_store-registers): Translate between
|
||
nindy and GDB formats for the registers.
|

|
||
(vx_read_register, vx_write_register): Cleanup status checking.
|
||
#ifdef the code based on which CPU we are using (960 or 68k),

||
(vx_xfer_memory, vx_resume): Cleanup status checking.
|
||
(vx_run_files_info): Improve message.
|
||
(vx_load_command): Renamed from vx_add_file_command. Allow load
|
||
to be interrupted.
|
||
(net_ptrace): Remove unused routine.
|
||
(vx_wait): Adopt code from vxgdb960 to cope with broken
|
||
connections to target machine and prompt to disconnect. Remove
|
||
debug printouts. Map some EVENT_'s to SIGnals.
|
||
(add_symbol_stub, vx_open): Print names of object files we found,
|
||
and "ok" if we read their symbols OK. Clarify output in general.
|
||
(vx_attach, vx_detach, vx_kill): Add these commands.
|
||
(vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
|
||
(vx_run_ops): Turn off all_mem, to avoid spurious msg in the
|
||
"info files" output, and create_inferior, since we already have
|
||
an inferior.
|
||
|
||
* stack.c (frame_info): Replace Frame_unknown with 0.
|
||
(print_frame_arg_vars): Handle LOC_LOCAL_ARG.
|
||
(return_command): Pop until the PC matches as well as the FP,
|
||
so it works even if the FP is shared with another function,
|
||
as in "frameless" or "leaf" procedures.
|
||
|
||
* symfile.c (load_command): renamed from add_file_target_command.

|
||
(add_syms_command): Stub to call target_add_syms.
|
||
(_initialize_symfile): Change command names and descriptions,
|
||
add-file => add-syms, and load from alias to its own command.
|
||
|
||
* target.c (kill_or_be_killed, maybe_kill_then_attach,
|
||
maybe_kill_then_create_inferior): Default for attempts to start
|
||
a process, if one is already running, is to ask about killing
|
||
it and retry if yes.
|
||
(upstack_create_inferior): #if-0 it, strata obsolete it.
|
||
(push_target, unpush_target, pop_target): to_close() a target
|
||
before unstacking it.
|
||
(target_info): Renamed from target_files_info.
|
||
(_initialize_targets): Rename "i files" as "i target", accessible
|
||
under both names.
|
||
|
||
* target.h: Improve comments about the target_ vectored routines.
|
||
|
||
* tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
|
||
Convert commenting style to standard GNU style.
|
||
(DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
|
||
(SKIP_PROLOGUE): No longer a no-op.
|
||
(SAVED_PC_AFTER_CALL): Now handles leaf procedures.
|
||
(*_REGNUM): Sort register numbers.
|
||
(REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
|
||
MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
|
||
REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
|
||
are now 10 byte extendeds, not 8 byte doubles.
|
||
(FRAME_CHAIN_VALID): Make this config-dependent, since it differs
|
||
for nindy versus vxworks targets. FIXME, this should possibly go
|
||
in the target vector.
|
||
(EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
|
||
frame_saved_regs and arg pointer with each frame.
|
||
(FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
|
||
(FRAME_ARGS_ADDRESS): Use cached result.
|
||
(FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
|
||
(FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
|
||
(PRINT_RAMDON_SIGNAL): Call print_fault.
|
||
(POP_FRAME): Now works.
|
||
|
||
* tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
|
||
option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
|
||
BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
|
||
(ADDITIONAL_OPTION_HANDLER): use target_load, not
|
||
target_add_file.
|
||
|
||
* tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
|
||
startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
|
||
|
||
* valarith.c (value_subscripted_rvalue): Avoid handling
|
||
floats and doubles specially; it gave alignment errors. Lint.
|
||
|
||
* valops.c (value_of_variable, value_of_this): Error if unknown
|
||
value.
|
||
|
||
* valprint.c (print_floating): Bcopy rather than pointer-deref,
|
||
to avoid alignment problems.
|
||
(value_print): Handle unknown value address.
|
||
(cplus_val_print): Two args are ignored; remove them. Change caller.
|
||
(val_print): Use unpack_long rather than pointer-deref.
|
||
|
||
* values.c: Lint.
|
||
(unpack_long, unpack_double): Use bcopy rather than pointer-deref
|
||
to avoid alignment problems.
|
||
(value_being_returned): Error if return value unknown.
|
||
(set_return_value): Add bogosity warning, FIXME. *
|
||
|
||
* TODO: A woman's work is never done.
|
||
|
||
* Makefile.dist: Distribute REMOTE_OBS into tconfig files.
|
||
Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
|
||
Add ieee-float.o to OBS.
|
||
* tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
|
||
REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
|
||
* tconfig/i960: FIXME. Half-merge, produce warning if config'd.
|
||
|
||
Changes to generalize the VxWorks RPC protocol slightly, to handle
|
||
i960 as well as 68000.
|
||
|
||
* vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
|
||
* vx-share/reg.h: Produce i960 regs #ifdef I80960
|
||
* vx-share/xdr_ptrace.c: Skip FPA registers if 960.
|
||
* vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
|
||
* vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
|
||
* vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
|
||
for i960. Change xdr_vectors to xdr_opaques for 68k registers,
|
||
so they will move in target byte order rather than network
|
||
byte order (happens to be the same).
|
||
|
||
Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
|
||
|
||
Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* am29k-pinsn.c,
|
||
Add contribution lines to various files, showing where they
|
||
came from.
|
||
|
||
* breakpoint.c (break_insn, check_break_insn_size,
|
||
read_memory_nobpt): Remove to mem-break.c.
|
||
|
||
* xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
|
||
HOST_BYTE_ORDER.
|
||
|
||
* tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
|
||
entry has bad register number. This change is not
|
||
tested in this release, FIXME.
|
||
|
||
* frame.h: Eliminate Frame_unknown in favor of a simple zero.
|
||
tm-vax.h: Ditto.
|
||
|
||
* value.h: Force value's contents field to be aligned to hold
|
||
at least a double or a long long (if supported). This avoids
|
||
doing bcopy's in and out of the contents field.
|
||
|
||
(step_1): Avoid coredump under obscure circumstances when we
|
||
have no frame.
|
||
|
||
* symtab.h (misc_info): Add field to misc function vector for
|
||
any kind of cached information the target code desires. AMD
|
||
29000 uses this to avoid repeating examine_function_prologue's.
|
||
|
||
* coffread.c: Lint. Remove static symfile, read_section_header.
|
||
core.c (have_core_file_p): Lint: remove.
|
||
expprint.c (print_subexp): Lint.
|
||
infptrace.c, valops.c, valprint.c: lint.
|
||
|
||
Roll in changes from vxgdb-5.0.1:
|
||
|
||
* symtab.h: Comment byte order of each address class. Add
|
||
LOC_LOCAL_ARG for frame-relative args (960).
|
||
expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
|
||
symtab.c, symmisc.c: ditto.
|
||
|
||
* infrun.c (init_wait_for_inferior): Clear stop_signal.
|
||
|
||
* remote.c (remote_resume): Error if resume with a signal.
|
||
|
||
* symfile.c (prim_record_misc_function): Clear misc_info.
|
||
(fill_in_vptr_fieldno): Check stub type of arg.
|
||
|
||
* valops.c (value_cast): Avoid looking up names of types whose
|
||
name we don't know, to prevent coredump. Sun CC produces typedef
|
||
rtx and the name of *rtx is zero...
|
||
|
||
Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Roll in changes from final AMD 29000 port (Tiemann).
|
||
|
||
tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
|
||
for ../include/a.out.encap.h. This might not work now that BFD
|
||
is separately compiled. Instead, BFD support for encap will have
|
||
to translate machine type 29k into the right COFF_MAGIC.
|
||
|
||
* infcmd.c: Remove references to inferior_pid that aren't used
|
||
in actual ptrace calls; use target_has_execution, etc.
|
||
(have_inferior_p): Remove function.
|
||
(program_info): Print target info rather than "process number";
|
||
avoid gratuitous messages unless from_tty.
|
||
(run_stack_dummy, finish_command): Set proceed_to_finish.
|
||
infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
|
||
main.c: Lint. Lose have_inferior_p().
|
||
inferior.h (have_inferior_p): Remove, lint.
|
||
(proceed_to_finish): Add flag to ask that all regs be saved
|
||
by normal_stop, for the few commands that need it, speeding up
|
||
serial I/O. Add comments to stop_registers.
|
||
|
||
* remote-eb.c: Remove newline from breakpoint message we grep
|
||
for. Never time out when running the user program.
|
||
|
||
|
||
|
||
Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Roll in changes from vxgdb-5.0.1:
|
||
|
||
* dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
|
||
symbol in its raw form, we are processing an unlinked ".o" file.
|
||
See if the target environment has assigned it an address, using
|
||
target_lookup_symbol (VxWorks does), and enter it into the symtab
|
||
that way.
|
||
|
||
* tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
|
||
68k versions for a simpler version that assumes zero FP at bottom.
|
||
Fixes bug of truncated stack reports.
|
||
|
||
* target.h (target_lookup_symbol): Define this routine's args
|
||
and result, finally.
|
||
|
||
* target.c (nosymbol): Default routine for target_lookup_symbol.
|
||
(target_default): Default lookup_symbol and call_function too.
|
||
(files_info): Only print has_all_memory warning if a non-dummy
|
||
target follows.
|
||
|
||
* remote-vx.c (vx_read_register, vx_convert_to_virtual,
|
||
vx_convert_from_virtual): If target does not have floating point,
|
||
zero register "values", and avoid doing cross-net conversions.
|
||
(vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
|
||
(vx_open): Rearrange code that attaches to target and reads
|
||
symbols for all loaded modules, to work if some of the modules
|
||
are not accessible. Add symbol_stub() and add_symbol_stub()
|
||
as callbacks from catch_errors(). Allow connect attempt to be
|
||
interrupted painlessly with ^C (FIXME, there are still some bugs
|
||
if the interrupt happens during symbol reading.). Print
|
||
final message with puts_filtered, since symbol messages are
|
||
now filtered too.
|
||
|
||
Misc cleanup:
|
||
|
||
* main.c (catch_errors): Only print errstring if non-null.
|
||
(command_loop): Avoid an ioctl per command to test ISATTY.
|
||
|
||
* remote-vx.c (net_load): make static; avoid sophomoric msg.
|
||
(vx_xfer_memory): Return correct result!
|
||
(vx_files_info): Indicate whether target has float or not.
|
||
(vx_lookup_symbol): Complain, not error, if target gone.
|
||
(vx_open): Print "Connected" msg before disabling immediate-quit.
|
||
[FIXME: lookup_symbol and vx_open changes need testing.]
|
||
|
||
target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
|
||
tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
|
||
contributor lines and update copyrights to 1991.
|
||
|
||
Changes from an attempted H-PUX host port:
|
||
|
||
* infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
|
||
defines PT_ATTACH and PT_DETACH but not PT_KILL.
|
||
* remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
|
||
* remote-vx.c: include <sys/time.h> for HPUX.
|
||
* hp300hpux-xdep.c (fetch_core_registers): Rewrite old
|
||
"core_file_command" routine to BFD regime. May not work yet.
|
||
|
||
Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
|
||
|
||
* xgdb.c: Replace X10 version with some VJ version.
|
||
(FIXME: Its copyright assignment is not on record.)
|
||
* xgdb.c: Update include files to X11R4 (Xaw crud).
|
||
(xgdb_display_source, create_text_widget): fix call to
|
||
get_filename_and_charpos. Rewack source window stuff for X11R4
|
||
(gleaned from include files, and "nm's" of binary libraries, since
|
||
I had no doc available).
|
||
(append_selection, append_selection_word): Disable with FIXME
|
||
since R4 changed interface here.
|
||
(create_buttons): Add back the old set of buttons.
|
||
(xgdb_create_window): Fix call to XtInitialize (&argc not argc).
|
||
|
||
* Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
|
||
Roll VERSION to 3.94 (not yet final though).
|
||
|
||
Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
|
||
obstack_int_grow, obstack_int_grow_fast): Eliminate
|
||
cast on left of assignment, which gives MIPS cc fits and is
|
||
not Standard C.
|
||
|
||
* sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
|
||
F_ALIAS. Use printf, not fprintf, when not passing a file
|
||
pointer...
|
||
(compare_opcodes): Check that identical instructions have
|
||
identical opcodes, complain otherwise.
|
||
|
||
* sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
|
||
was reported by Roland McGrath.
|
||
(unimp): Only match if exactly zero instruction. (Roland)
|
||
(branches and traps): Generate all variations of these
|
||
instructions with macros, based on a single call that defines
|
||
each condition name and its binary representation.
|
||
(set): Turn on alias bit, to avoid test in sparc-pinsn.c.
|
||
|
||
* valprint.c (val_print_fields): Take, and use, format parameter.
|
||
This means that "p/x struct" again prints the elements in the
|
||
desired format. Changed callers.
|
||
|
||
* stack.c (frame_info): Use filtered output, and indicate wrap
|
||
points. Remove kludgy formatting designed to avoid line wrap.
|
||
|
||
* utils.c (wrap_here): If the line is already full (because
|
||
we had printed a long indent or long wrapped string), do an
|
||
immediate newline-and-indent.
|
||
|
||
* m68k-pinsn.c (print_insn_arg): Bugfix from
|
||
ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
|
||
instruction is incorrectly disassembled as bkpt #8.
|
||
|
||
* dbxread.c (end_psymtab): Bugfix from Peter Schauer
|
||
<pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
|
||
breakpoint in a *.y file gdb will say Reading in symbols for *.y...
|
||
and then will dump core (sometimes). I traced it back to an
|
||
uninitialized symfile_name in psymtab_to_symtab.
|
||
(const_vol_complaint): Add quotes to message.
|
||
(define_symbol): Only believe line number if gcc_compiled.
|
||
Avoid allocating symbol if we will not return it.
|
||
|
||
Add target strata support so that newly established targets go
|
||
into their right place in the target stack (e.g. a new exec file
|
||
doesn't wipe out the ability to access the running process).
|
||
|
||
* target.h, core.c, exec.c, inftarg.c, remote-eb.c,
|
||
remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
|
||
and initialize it properly in all the targets.
|
||
|
||
* target.h: Document strata. Change return type of push_target.
|
||
|
||
* target.c (nomemory): new function for dummy memory access.
|
||
(tcomplain): Rename complain, now also used in symfile.c.
|
||
(push_target): Push targets within strata. New return value shows
|
||
whether new target is on top of stack or not. Always keep dummy
|
||
target on stack.
|
||
(target_files_info): Ignore dummy target.
|
||
|
||
* core.c (core_open): Warn user, and skip accessing file, if the
|
||
core target is not the topmost target in the stack.
|
||
* remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
|
||
already handled.
|
||
|
||
* remote-vx.c: Remove vx_prepare_to_store from vxworks memory
|
||
target_ops, it doesn't belong there since we have no regs there.
|
||
Change name of target from machine => memory to clarify.
|
||
|
||
Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
|
||
|
||
* Freeze version 3.93 for release.
|
||
|
||
* Makefile.dist: Handle vx-share and nindy-share subdirs
|
||
properly when building gdb.tar.Z.
|
||
|
||
* symtab.c: lint; add no_symtab_msg to consolidate the messages
|
||
printed in various places, so I could change just one copy.
|
||
|
||
* dbxread.c, coffread.c: Change references to bfd->iostream
|
||
to cast to FILE *, now that BFD avoids needing types defined
|
||
in other header files.
|
||
|
||
Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
|
||
infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
|
||
sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
|
||
(actually gcc -Wall).
|
||
|
||
* dbxread.c: Remove first_global_sym, last_global_sym, since
|
||
they are never referenced.
|
||
|
||
* defs.h (baud_rate): Declare.
|
||
main.c: Define it, and add the -b option to set it.
|
||
|
||
* gdb-int.texinfo: Add text on how to define a new host or target
|
||
architecture, prompted by Per Bothner's questions about MIPS
|
||
support.
|
||
|
||
* gdb.texinfo: Document "complaints". Change doc of -q since
|
||
gdb no longer prints the copyright and blurb if you specify a file
|
||
name to be debugged (just like Emacs). Add doc for Nindy-specific
|
||
command line flags for specifying target serial port and such.
|
||
Update copyright to 1991.
|
||
|
||
* gdbcore.h: Remove a large mass of now-useless crud, since BFD
|
||
has taken over for us the job of ripping up executable files. The
|
||
crud caused Per Bothner's port to not compile.
|
||
|
||
* infrun.c (normal_stop): Avoid printing "Program exited
|
||
normally" if we are in batch mode. This allows a GDB which
|
||
executes a program on a target system, to behave like a Unix
|
||
command (input from stdin, output to stdout, no extraneous
|
||
output).
|
||
|
||
* main.c (main): Allow additional machine-dependent command line
|
||
options to be specified with the ADDITIONAL_OPTIONS,
|
||
ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
|
||
ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
|
||
processing to occur just before the main loop with
|
||
BEFORE_MAIN_LOOP_HOOK.
|
||
(main): If a "core file" argument is specified, and it is not a
|
||
core file, try it as a process ID to attach.
|
||
(symbol_completion_function): Attempt to cope with
|
||
"show screen-" TAB, not very successfully. This needs more work,
|
||
FIXME.
|
||
(batch_file): New function, returns whether we are reading
|
||
commands from an interactive tty on stdin, or from somewhere else.
|
||
Called by normal_stop since it doesn't get from_tty passed down
|
||
to it like many commands do.
|
||
|
||
* remote-nindy.c: Handle command line options for nindy
|
||
connection.
|
||
(nindy_before_main_loop): Prompt user for tty name if they
|
||
don't specify it before getting to the interactive command loop.
|
||
|
||
* tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
|
||
and -r command line options. Also add hook before main loop
|
||
to make it easy to specify a tty.
|
||
|
||
* TODO: More things to do, one done.
|
||
|
||
Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
|
||
|
||
* dbxread.c: Make complaint() calls pass pointer, not struct.
|
||
Add complaints about badly formatted C++ type information
|
||
(const/volatile indicator, and parse errors resulting in
|
||
error_type). Fix C++ virtual member fn comment.
|
||
(read_struct_type): Avoid bumping pointer if we got a parse
|
||
error; this prevents our walking beyond the end of a string.
|
||
Terminate loop on null char as well as semicolon.
|
||
(process_one_symbol): Fix the LBRAC fix so that it uses the
|
||
last previous SLINE, FUN, or SO record's PC address. C++ debug
|
||
symbols did not have SLINE records in a useful order compared
|
||
to the LBRAC records.
|
||
(define_symbol): Handle "catch" records.
|
||
|
||
* symtab.c (check_stub_type): Added new complain
|
||
`stub_noname_complain' and added a consistency check to
|
||
keep the debugger from crashing when finishing from an
|
||
exception frame. A real fix will be needed later.
|
||
|
||
Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* infcmd.c (attach_command): Make global.
|
||
|
||
* Makefile.dist (REMOTE_OBS): Make these compile by default,
|
||
but make them easy to comment out. Perhaps later they should
|
||
be enabled by what CPU you configure for? FIXME.
|
||
(VERSION): Roll to 3.93.
|
||
(pinsn.o): Remove rule for obsolete file.
|
||
(dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
|
||
|
||
Run down a problem that manifested by printing the wrong function
|
||
name in stack traces of read_ofile_symtab. Turned out that the
|
||
problem was the SunOS 4.1.1 (and previous) C compiler outputs
|
||
the LBRAC symbol with an address in the *data* segment, which
|
||
blew our binary search through the blocks.
|
||
|
||
* dbxread.c: Use the complain() facility consistently to bitch
|
||
about problems in the symbol file we are reading.
|
||
(finish_block): Add code to check the nesting of the blocks;
|
||
complain and Procrust them to fit if wrong.
|
||
(make_blockvector): Check the order of the blocks, complain
|
||
[but don't cope] if wrong.
|
||
(process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
|
||
symbols to be sure their PC value is greater than the last SLINE
|
||
(line number) symbol we've seen, complaining and adopting the
|
||
SLINE PC value if wrong.
|
||
|
||
* symfile.h (struct complaint, complaint_root, complain,
|
||
clear_complaints): Add.
|
||
* symfile.c (complain, complaint_root, clear_complaints): Add
|
||
facility to deal with non-fatal complaints and to regularize their
|
||
suppression.
|
||
(symbol_file_add): Clear complaint counters to allow new complaints.
|
||
(initialize_symfile): Add 'set complaints' and 'show complaints'.
|
||
|
||
* dbxread.c (dbx_symfile_read): Remember the address and size
|
||
of the string table for the main symbol file, so we won't read it
|
||
more than once.
|
||
(dbx_psymtab_to_symtab): Fix the check for main symbol file,
|
||
to avoid reading the string table yet again. Lint.
|
||
(throughout): Improve filtered output, including word wrap.
|
||
(read_range_type): Improve Bothner's fix to handle other types too.
|
||
|
||
* utils.c: Improve line wrap implementation. Handle unlimited
|
||
width by making chars_per_line unsigned.
|
||
(puts_filtered): New, easy, function.
|
||
|
||
* defs.h (puts_filtered): add.
|
||
|
||
* mipsread.c (compare_symbols, sort_symtab): Remove these fns,
|
||
call the identical sort_symtab_syms() in symfile.c instead.
|
||
|
||
* expread.y: Suggest the `file' command rather than `symbol-file'.
|
||
|
||
* command.h (enum var_types): Add zinteger for seroable
|
||
unsigned integer.
|
||
* command.c (do_setshow_command): Handle var_zinteger. Restructure
|
||
nested if's into a switch.
|
||
|
||
* breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
|
||
we did not stop because of a breakpoint (it must have been for
|
||
some other reason, like a "stepi"), so don't print anything.
|
||
|
||
* symtab.c: Include <sys/types.h> all the time. Now that BFD
|
||
doesn't include <sys/types.h>, old SunOS's require it for
|
||
<sys/stat.h>.
|
||
|
||
Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
|
||
|
||
A test port of gdb-3.92.6 to the Sony NEWS.
|
||
|
||
* Makefile.dist
|
||
Don't normally link in remote- or vx stuff.
|
||
Some of it doesn't compile, and it wastes space for 99% of the users.
|
||
Remove reference to no-longer-used HAVE_VPRINTF.
|
||
Fixed BFD_DEP typo to BFD_DIR.
|
||
* dbxread.c
|
||
Fix cast in arg to bfd_h_getlong.
|
||
Make char *prefix be const.
|
||
Fix how certain range types are mapped into builtin unsigned int types.
|
||
* infrun.c
|
||
Remove 2 #includes. They cause errors (on Sony, at least),
|
||
and aren't needed (they wern't in earlier versions).
|
||
* printcmd.c
|
||
print_address_symbolic should never demangle labels
|
||
(since it prints *assembler-level* labels).
|
||
|
||
[This was superseded by the change to printcmd below.]
|
||
|
||
* utils.c
|
||
Add some "volatile" return types to avoid warnings.
|
||
If MISSING_VPRINTF add vprintf function and not just macro
|
||
(since vprintf is used in printcmd.c).
|
||
* valprint.c
|
||
Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
|
||
(The latter isn't grokked by some PCC-based compilers.)
|
||
|
||
[This change is in abeyance, we prefer to fix obstack_ptr_grow.]
|
||
|
||
Make chunk size of dont_print_obstack 32*4 instead of default 4096.
|
||
* nindy-share/coffstrip.c
|
||
Added some forward declarations (otherwise, gcc complains
|
||
about implicit extern redefined as static).
|
||
|
||
Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Changes inspired by Per Bothner:
|
||
* printcmd.c (print_address_symbolic): Take additional parameter
|
||
specifying whether to demangle.
|
||
(print_address): Pass in asm_demangle to control demangling.
|
||
(print_address_demangle): New fn, takes explicit arg to control
|
||
demangling.
|
||
* utils.c: Add new vars demangle and asm_demangle, and let them
|
||
be set and shown.
|
||
(fputs_demangled): If !demangle, just print the argument.
|
||
(fprint_symbol): If !demangle, just print raw symbol.
|
||
* valprint.c (val_print): Call print_address_demangle rather than
|
||
print_address, to cause demangling to depend on the global
|
||
rather than assembler-level demangling setting.
|
||
* WHATS.NEW, gdb.texinfo: Document.
|
||
|
||
* main.c (show_command): Show all settings if no arg.
|
||
(initialize_main): Make "info set" the same as naked "show".
|
||
* command.c (cmd_show_list): Handle prefix commands in the
|
||
list, and print the name of the setting as well as its English
|
||
description and value.
|
||
|
||
Allow gdb functions to specify where a line should wrap if it
|
||
exceeds the size of a terminal line. Use it to make the output
|
||
prettier.
|
||
* utils.c (set_screen_width_command): New fn, mallocs a buffer
|
||
of the right size when screen width changes.
|
||
(set_screensize_command, screensize_info): Remove #if 0'd fns.
|
||
(wrap_here): New fn, indicates a point in the output where we
|
||
should wrap the line rather than just letting it overflow at a
|
||
random place.
|
||
(fputs_filtered): Implement wrapping.
|
||
(n_spaces): New fn, returns a pointer to N spaces.
|
||
(print_spaces_filtered): Use n_spaces.
|
||
* defs.h (n_spaces): Declare.
|
||
* stack.c (print_frame_info): Wrap with 4-space indent after
|
||
fn name and before filename and line number.
|
||
* printcmd.c (print_frame_args): Wrap with 4-space indent
|
||
before each argument name is printed.
|
||
* valprint.c (value_print): Wrap with no indentation before
|
||
each repetition.
|
||
(val_print_fields): Wrap with indentation relative to nesting
|
||
level before each field name.
|
||
(val_print): Wrap with nesting indentation before array elements.
|
||
* command.c (do_setshow_command): Avoid extra newlines,
|
||
wrap with 4-space indent around values printed, end with period.
|
||
* WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
|
||
|
||
* breakpoint.c (breakpoint_1): Implement addressprint for
|
||
"info breakpoints" display. Change file name and line number
|
||
format to " at file:nnn" rather than " (file line nnn)".
|
||
* gdb.texinfo: Document.
|
||
|
||

Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
Frozen for gdb-3.92.6 release.
|
||
|
||
README, WHATS.NEW: Update for 3.92.6 release.
|
||
|
||
tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
|
||
coffread.o from configs since it is now built by default.
|
||
tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
|
||
i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
|
||
pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
|
||
from configs since it is now built by default.
|
||
|
||
Makefile.dist: Update for release 3.92.6. Handle files that
|
||
have been moved to ../include, ../getopt, or ../bfd. Add
|
||
saber.suppress and tests directory. Add config.status to
|
||
the release (it will say "none").
|
||
|
||
coredep.c: Minor formatting fixes.
|
||
|
||
These changes were made in early December but only checked in now:
|
||
* nindy-share/Onindy.c, nindy-share/coffstrip.c,
|
||
nindy-share/nindy.c: lint
|
||
* nindy-share/nindy.c (ninStopWhy): Don't byteswap the
|
||
register values coming back from the target; we store values
|
||
in target byte order everywhere.
|
||
|
||
Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||
|
||
* am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
|
||
|
||
* valprint.c (cplus_val_print, val_print_fields): New functions,
|
||
which print C++ objects. They conspire to avoid printing a
|
||
virtual base class more than once, following all the twists and
|
||
turns of C++ virtual base rules.
|
||
(val_print): Call the above rather than do it by hand.
|
||
|
||
* symfile.c (symbol_file_add): Only reset symfile_mtime for main
|
||
symbol file, not for added files like shared libs. This really
|
||
needs to be generalized to a timestamp per file.
|
||
|
||
* core.c (cleanup_core): Avoid coredump if no core file.
|
||
|
||
* config.gdb: Accept -host or -target in place of +host or
|
||
+target.
|
||
|
||
* coffread.c (find_linenos): Avoid desupported BFD interface
|
||
to line numbers. We still read them manually rather than using
|
||
BFD's "generic" features.
|
||
|
||
* gdbrc.tex, threecol.tex: Add GDB reference card and its
|
||
formatting code.
|
||
Makefile.dist: Add refcard to OTHERS list for creating tar files.
|
||
|
||
* Makefile.dist: Eliminate use of $< in explicit targets.
|
||
|
||
* readline/Makefile: Use $< rather than $*.c, which does not
|
||
include the VPATH in GNU Make.
|
||
|
||
* tconfig/i960-bout, tconfig/i960-coff: These are identical
|
||
copies of tconfig/i960, added for global configuration
|
||
compatability. All i960 versions can read both coff and b.out.
|
||
|
||
* tm-88k.h: Fix multiline macro that lacked \'s. Remove
|
||
COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
|
||
automaticaly.
|
||
|
||
* TODO: Think of more things to do.
|
||
|
||
Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
|
||
|
||
tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
|
||
of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
|
||
64-bit float conversion.
|
||
|
||
tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
|
||
equivalent to sun?os4 so global config works.
|
||
|
||
Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
|
||
|
||
Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
|
||
|
||
* main.c: Only declare linesize once; declare pagesize not at
|
||
all, since it is never used.
|
||
(main): Clear newly allocated line before it is used.
|
||
|
||
Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
|
||
|
||
Further stabilization for the Intel 960.
|
||
|
||
* Makefile.dist: Parameterize the location of the "include"
|
||
and "bfd" directories, as well as "getopt". Add symfile.c.
|
||
Link in both dbxread and coffread. Fix up "make depend" to
|
||
rewack the locations of include, bfd, and getopt in its output.
|
||
|
||
* README: Document moving include files, improve some of
|
||
the other doc.
|
||
|
||
* coffread.c: Move common code out to symfile.c. Change
|
||
symbol_file_command style interface to use new *_symfile_init
|
||
and *_symfile_read interface under BFD. Use BFD internal
|
||
info to locate line table, symbols, etc.
|
||
|
||
* core.c (core_fetch_registers): Rename to get_core_registers
|
||
to avoid confusion with fetch_core_registers.
|
||
(register_addr): Move to coredep.c, which is already machine
|
||
dependent. This leaves core.c pretty clean of dependencies.
|
||
|
||
* coredep.c (register_addr): Accept this routine from core.c.
|
||
|
||
* dbxread.c: Move common code (with coffread.c, etc) into new
|
||
symfile.c. Each psymtab now contains a pointer to the
|
||
format-dependent function that knows how to read it in. Make
|
||
some things static.
|
||
(dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
|
||
(process_one_symbol): Add code to complain about a "compiler bug
|
||
we muzzle here", if we actually see it.
|
||
|
||
* eval.c (evaluate_subexp): Insert missing "break" statements
|
||
in code that determines whether a variable is an lvalue in
|
||
memory, register, or whatever. I detected this via a compiler
|
||
bug in which it *almost* mashed out the whole switch statement.
|
||
|
||
* gdb-int.texinfo: Add minor sections on configuring gdb for
|
||
release, and about the README file.
|
||
|
||
* infcmd.c (registers_info): Fix formatting somewhat. Still
|
||
not as pretty as before, but it handles byte swapping.
|
||
|
||
* remote-nindy.c: If data cache routines are interrupted while
|
||
waiting for the remote end, be sure that any uninitialized cache
|
||
blocks are on the free list, not on the valid list!
|
||
|
||
* symfile.h: Flesh out this header file with all the various
|
||
routines and variables that have been merged in from dbxread.c
|
||
coffread.c, and symtab.c to symfile.c.
|
||
|
||
* symfile.c: New file, containing code common to dbxread.c,
|
||
coffread.c, and some code from symtab.c. All generic code for
|
||
reading symbol files should be in here now.
|
||
(unrecord_misc_function): Remove unused function.
|
||
|
||
* symtab.h: Remove file-reading things to symfile.h.
|
||
|
||
* symtab.c: Remove file-reading things to symfile.c.
|
||
|
||
* tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
|
||
to decode i960 fault types.
|
||
|
||
* target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
|
||
target.c: Change type of the "resume" function from int to void,
|
||
since its result was never used.
|
||
|
||
Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
|
||
|
||
* main.c: Replace "stupid" with "caution"; you now "set caution
|
||
on or off".
|
||
|
||
* printcmd.c (print_scalar_formatted): Fix typo in 'g' format
|
||
|
||
* infcmd.c (do_registers_info): Call val_print to deal with the
|
||
byte order of the registers being printed. FIXME, this makes
|
||
the formatting of the output uglier.
|
||
|
||
* infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
|
||
defined, call it for signals the debugger doesn't itself use.
|
||
The i960 uses this for more detailed fault information.
|
||
|
||
* remote.c (remote_open): If arg is null, print help rather than
|
||
dumping core.
|
||
|
||
* sparc-xdep.c (register_valid): Avoid declaring size, since
|
||
various modules will think of various sizes depending on the
|
||
architecture of their tm-file. FIXME, we need protection against
|
||
actually entering one of those modules, which would clobber
|
||
storage if not for the target architecture compiled into gdb.
|
||
|
||
* stack.c (up_command, down_command): Always print the frame
|
||
you arrive at.
|
||
(up_silently_command, down_silently_command): New commands
|
||
for use in scripts.
|
||
|
||
* i960-pinsn.c (reg), i960-tdep.c: Lint.
|
||
|
||
* i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
|
||
more parameters than it used to.
|
||
|
||
* findvar.c (registers): Increase slop to 256 bytes, which should
|
||
protect us against even most RISC machines with large register
|
||
sets.
|
||
(locate_var_value): Move declaration inside related ifdef.
|
||
|
||
* remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
|
||
throughout, to avoid throwing away buffered input from the board.
|
||
(nindy_wait): Supply_register takes addr_of_value, not value.
|
||
(i960_print_fault): Renamed from i80960_fault.
|
||
(nindy_fetch_registers): Avoid have_regs stuff, just get them.
|
||
(nindy_store_registers): Avoid regs_changed stuff, just stuff
|
||
them.
|
||
(nindy_create_inferior): Don't bother to write PC_REGNUM since
|
||
we can set the PC in the call to proceed(). Unpush nindy_ops
|
||
before pushing it on top, to avoid message to user. Eliminate
|
||
commentary from Unix machines that just misleads here.
|
||
(reset_command): Fix error message to suggest target command.
|
||
|
||
Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
|
||
|
||
Release 3.92.5 as frozen.
|
||
|
||
Stabilize the merged release...with help from lint, Saber C,
|
||
gcc -W, etc.
|
||
|
||
Everywhere: Add include files needed to declare return types
|
||
of functions called.
|
||
|
||
* gdb.texinfo: Roland Pesch is documenting gdb, glory be!
|
||
|
||
* breakpoint.h: Add undeclared breakpoint functions, and some
|
||
functions for display handling since I couldn't think of a better
|
||
.h to put them in.
|
||
|
||
* breakpoint.c (insert_breakpoints): Make code for disabling
|
||
shared library bkpts more likely to work. It's used when we
|
||
rerun a program and stop before the shared library has been
|
||
mapped in.
|
||
(breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
|
||
cast from pointer, so it squeezes through catch_errors.
|
||
(bpstat_stop_status): Fix logic broken some time ago. We now
|
||
always create a bpstat if the stop address matches a breakpoint,
|
||
even if we don't stop there -- just like the old code used to do
|
||
before I got my fingers into it (sigh).
|
||
(breakpoint_1): Print "ignore count" after "stop only if"
|
||
condition, since that's how it actually works.
|
||
(mention): Handle watchpoints as well as breakpoints.
|
||
(watch_command): use set_raw_breakpoint and mention to do most
|
||
of the work (and initialize all the fields!). Only pass one
|
||
arg to parse_c_expression, since that's all it takes.
|
||
|
||
* command.c (not_just_help_class_command): Rename arg to args
|
||
since we ignore "unused argument" warnings on vars named "args".
|
||
inflow.c (child_terminal_info): ditto.
|
||
infptrace.c (kill_inferior): ditto
|
||
main.c (catch_errors, version_info, quit_command, pwd_command,
|
||
source_command, dump_me_command, editing_info,
|
||
set_history_size_command, set_history, show_history,
|
||
set_verbose): ditto
|
||
stack.c (locals_info): ditto
|
||
target.c (target_files_info): ditto
|
||
valprint.c (set_input_radix, set_output_radix): ditto
|
||
|
||
* core.c: Remove old variables for handling core and exec file
|
||
sections (data_start, data_end, stack_start, stack_end,
|
||
reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
|
||
text_end, exec_data_start, exec_data_end, text_offset,
|
||
exec_data_offset, data_offset, stack_offset). They're
|
||
superseded the more general build_section_table and
|
||
xfer_memory.
|
||
(get_exec_file): Mention the `file' command.
|
||
(read_memory_check): Rename to memory_error, and only call it
|
||
in the case of an actual error.
|
||
(read_memory, write_memory): call memory_error.
|
||
(core_fetch_registers): Register section name is ".reg".
|
||
|
||
coredep.c: Remove a bunch of crud now that all this file does
|
||
is pull the registers out of a core file.
|
||
(fetch_core_registers): Rewrite to actually work, I hope.
|
||
|
||
dbxread.c: Use a.out.gnu.h, not system a.out, now.
|
||
Replace index() with strchr(). Remove all the pre-BFD macro
|
||
definitions for accessing the symbol file.
|
||
(struct dbx_symfile_info): Encapsulate the information that
|
||
dbx_symfile_init needs to pass to dbx_symfile_read in this
|
||
struct.
|
||
|
||
(dbx_new_init, dbx_symfile_init, dbx_symfile_read,
|
||
dbx_symfile_discard): Rearrange symbol file reading to divide
|
||
the format-specific part from the format-independent part,
|
||
leaving the format-independent part such as file name expansion
|
||
and opening in symtab.c. This replaces
|
||
partial_symbol_file_open and partial_symbol_file_read.
|
||
Symbol_file_read, add_file, add_file_target_command,
|
||
add_file_addr_command move to symtab.c. Pass an explicit
|
||
"mainline" flag for when reading the main symbol table, rather
|
||
than relying on the offset address to be zero or nonzero.
|
||
|
||
(dbx_symfile_read): Don't allow void *'s to be printed as
|
||
typedefs.
|
||
(SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
|
||
(ADD_PSYMBOL_TO_LIST): Make the "function call rather than
|
||
macro" debug version really work.
|
||
(read_dbx_symtab): Remove unref'd parameter inclink.
|
||
Avoid swapping N_SLINE symbols, for speed.
|
||
Merge N_TEXT!N_EXT case with the other external symbol
|
||
definitions' case. Add comments.
|
||
(start_psymtab): Allocate the symfile name in the psymtab on
|
||

|
||
|
||
gdb-int.texinfo: New file, for GDB internals documentation.
|

Declare fetch_core_registers and registers_fetched.
|
||
|
||
getopt.c: Declare char *alloca(); even on SPARC.
|

|
||
* infptrace.c (child_xfer_memory): To avoid dependency on

|
||

|
||

|
||
we need the table for things other than psignal.
|
||
|
||
* solib.c (solib_add): Use symbol_file_add, not add_file.
|
||
(solib_address): Return boolean result rather than struct
|
||
pointer which nobody else knows the type of.
|
||
|
||
* sparc-tdep.c, valops.c: Use write_memory rather than
|
||
target_write_memory, to get error checking.

Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
|
||
|
||
Continuing Intel 960 port merge of GDB.
|
||
|
||
* Makefile.dist: Merge i960 "nindy-share" files. Rename
|
||
malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
|
||
Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
|
||
Wack over "make depend" so it handles files in subdirectories
|
||
vx-share, nindy-share, bfd, and in the current directory.
|
||
|
||
* blockframe.c (get_prev_frame_info): Remove fatal error
|
||
if stack not defined.
|
||
|
||
* core.c (core_open, core_detach): New functions that handle
|
||
the old "core-file" command as "target core" and "detach" instead.
|
||
(core_file_command): Call them.
|
||
(core_xfer_memory): Use common routine xfer_memory.
|
||
|
||
* dbxread.c: Include a.out.gnu.h, not system a.out.h.
|
||
dbxread now uses bfd for everything but symbol reading itself.
|
||
BFD internals are used to drag out the relevant file offsets.
|
||
(partial_symbol_file_open): Change args all around for BFD.
|
||
|
||
* symtab.c: Rename "value" to "val" everywhere, so we can
|
||
#include "value.h".
|
||
(symbol_file_command): New command, moved from dbxread.c
|
||
and coffread.c. It uses BFD to read the file, then vectors
|
||
based on its type, to dbx or coff symbol readers.
|
||
* symtab.h: Extern a few vars for symbol_file_command.
|
||
|
||
* target.h: Breakpoint takes a char * save area, not a char **.
|
||
|
||
* valprint.c (val_print): When unpacking bitfields, offset
|
||
the address in gdb of the value, if it is declared with a shorter
|
||
type. Remove the last "runtime kludge test" of host byte order.
|
||
|
||
* utils.c: Remove old my_bfd_read routine.
|
||
|
||
* stack.c (frame_info): Use target_has_stack. Print program counter
|
||
register's actual name rather than "pc", since it's called the
|
||
"ip" (instruction pointer) on the i960 (sigh).
|
||
|
||
* target.c (target_command): Add command for selecting a target
|
||
type and calling its open routine. This is used for initiating
|
||
communication with a particular target, in a generic way.
|
||
|
||
* tm-i960.h: Update for modern gdb. Remove semicolons from
|
||
various macros. Handle reading struct return convention, and
|
||
error-out attempts to return structs with the "return" command.
|
||
Be sure gdb doesn't think we know how to call functions in the
|
||
inferior.
|
||
|
||
* i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
|
||
to i960_xxx in lower case.
|
||
(arg_address): Circumvent errors due to LOC_ARG_BLOCK
|
||
not being defined yet.
|
||
|
||
* remote.c (remote_open): Call start_remote to initialize
|
||
wait_for_inferior during open.
|
||
(remote_xfer_inferior_memory): Return length written rather
|
||
than errno value.
|
||
|
||
* remote-vx.c (target_command -> vx_open): Use new generic
|
||
target command.
|
||
* remote-eb.c, inftarg.c, exec.c: ditto.
|
||
|
||
* infrun.c: Fix comments.
|
||
(attach_program -> child_open): Use new generic target command.
|
||
(wait_for_inferior): Clear saved register values before target_wait,
|
||
so target_wait can set some of them if convenient.
|
||
|
||
* infptrace.c (fetch_inferior_registers, store_inferior_registers):
|
||
Return success indicator, not void.
|
||
(child_xfer_memory): Avoid fetching initial word if we'll
|
||
overwrite it anyway.
|
||
|
||
* infcmd.c (attach_command): Use new generic target open routine.
|
||
(_initialize_infcmd): Update doc on attach and detach commands.
|
||
(do_registers_info): Merge in a byte-order problem as a FIXME
|
||
comment.
|
||
|
||
* findvar.c (find_saved_register): Avoid problem in current frame.
|
||
(read_relative_register): Ditto.
|
||
(write_register): Convert byte order on the way out.
|
||
|
||
* exec.c (file_command): Add.
|
||
(add_to_section_table, exec_command): Use new bfd_map_over_sections.
|
||
(xfer_memory): Common function between core_xfer_memory and
|
||
exec_xfer_memory.
|
||
(exec_xfer_memory): Use it.
|
||
|
||
* pn-opcode.h: Document that a "PN" is a Gould PowerNode.
|
||
|
||
* breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
|
||
valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
|
||
infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
|
||
|
||
Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
|
||
|
||
Merge Intel 960 port of gdb, continuing...
|
||
|
||
* dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
|
||
symbol_file_command): Pass from_tty arg to hush 'em up.
|
||
|
||
* coffread.c (symbol_file_command): Avoid output if from_tty != 1.
|
||
Add magic numbers for 960 COFF format.
|
||
|
||
Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
|
||
|
||
Merge Intel 960 port of gdb, from Intel "1.2" release.
|
||
|
||
CHANGE_LOG entries from their port, which was based on
|
||
gdb+-2.8.0:
|
||
|
||
Thu Sep 6 11:02:22 PDT 1990
|
||
Remove temp file if download is interrupted.
|
||
|
||
Wed Aug 1 09:08:33 PDT 1990
|
||
Now uses binary protocol to talk to NINDY.
|
||
Old hex protocol (NINDY 2.13 and older) supported with -O switch.
|
||
Times out after 5 seconds when trying to talk to NINDY.
|
||
|
||
Tue May 29 12:54:49 PDT 1990
|
||
Added variable baud rate (-b switch).
|
||
Source code reorganization.
|
||
|
||
Thu Apr 26 11:09:55 PDT 1990
|
||
More cleanup of batch mode; specifically, execute "-s", "-e", and
|
||
"-se" switches as soon as they are encountered on the invocation line.
|
||
|
||
Fri Apr 20 13:47:15 PDT 1990
|
||
Add -brk switch.
|
||
|
||
Thu Apr 19 09:54:28 PDT 1990
|
||
Add 'reset' command.
|
||
|
||
Wed Apr 18 09:48:07 PDT 1990
|
||
After opening remote tty, wait for 1 second to go by without input
|
||
from it before trying to talk to NINDY (fixes problems with the
|
||
Heurikon HK80/V960E).
|
||
|
||
Mon Apr 4 16:33:05 PDT 1990
|
||
Some output was not being suppressed in 'batch' mode.
|
||
|
||
Thu Mar 22 15:31:11 PST 1990
|
||
Ask user if old symbol table should be deleted when new file is
|
||
downloaded.
|
||
|
||
Allow user to run a program downloaded before gdb960 was brought up.
|
||
|
||
Correct "exec-file" help message for i80960 context.
|
||
|
||
Correct bug in calculating user space address: could occasionally
|
||
corrupt user program.
|
||
|
||
Make sure to zero low-order bits in rip's because of bug in 960CA
|
||
A-step part: could cause operation faults when "next"ing across
|
||
a function call.
|
||
|
||
Correct bug that made it impossible to get source line numbers for
|
||
code loaded at addresses higher than 0x7fffffff.
|
||
|
||
Wed Jan 10 12:43:22 PST 1990
|
||
Open remote tty for exclusive use.
|
||
|
||
Fri Jan 5 12:14:42 PST 1990
|
||
Correct disassembly (CA manual was right after all):
|
||
opcode for sysctl is 0x659
|
||
|
||
Mon Oct 23 12:03:04 PDT 1989
|
||
Use G960BASE and G960BIN environment variables to find 'sx' utility.
|
||
|
||
Mon Oct 16 14:15:09 PDT 1989
|
||
"sfr0"-"sfr31" should have been named "sf0"-"sf31"
|
||
|
||
Mon Oct 2 15:56:31 PDT 1989
|
||
|
||
Added 960CA disassembly support.
|
||
|
||
To simplify maintenance:
|
||
- eliminated use of symblic links on pinsn.c: use i960-pinsn.c
|
||
directly instead.
|
||
- eliminated opcode.h: incorporates tables into i960-pinsn.c
|
||
- moved 960-specific routines from i960-pinsn.c to i960-md.c
|
||
- made disassembly interface identical to that in gdmp960.
|
||
|
||
|
||
|
||
Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
|
||
|
||
* target.h: Allow targets to stack. Add target_has_memory,
|
||
_registers, etc. Restructure memory access and "info files"
|
||
to walk the target stack.

* remote-vx.c: New memory regime, new info files. Now use
|
||
separate targets for VxWorks attachment to machine, and

stack & execution & regs and the other doesn't.
|
||

|
||
* sparc-xdep.c (fetch_core-registers): New memory regime.

|
||
|
||
Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
|
||
|
||
Massive changes to wall off the remote-debugging interface
|
||
behind a function vector. The port to handle VxWorks targets
|
||
is also part of this.
|
||
|
||
All files: Replace references to renamed functions,
|
||
remove references to remote_debugging, remove references to
|
||
have_include_file, have_core_file in favor of target_has_stack,
|
||
target_has_memory, etc.
|
||
|
||
* Modularize the breakpoint interface.
|
||
breakpoint.h (BREAKPOINT_MAX): New define sets max length of
|
||
a breakpoint instruction.
|
||
breakpoint.c: struct breakpoint's shadow_contents now sized as
|
||
BREAKPOINT_MAX.

(remove_breakpoints): Vector to target here too.
|
||
Remove REMOTE_SA_SPARC kludges and other remote_debugging.

sparc-tdep.c (single_step): Use new breakpoint interface for
|
||
the single-step breakpoints.
|
||
mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
|
||
New file, contains routines to insert and remove breakpoints by
|
||
reading out the old contents and later replacing them. This is
|
||
how ptrace breakpoints work, and many remote systems as well.
|
||
|
||
* tm-vxworks68.h: New config file, overrides a few things for
|
||
Wind River's preferences.
|
||
|
||
* target.h: New file, for transfer vector used to talk to the
|
||
inferior (child, attached, core, exec, remote, etc). All accesses
|
||
to the thing being debugged should come through these vectors.
|
||
target.c: New file, routines to handle transfer vector.
|
||
(various files): Add transfer vectors XXX_ops for the various
|
||
targets and pseudo-targets (core files, etc) we support.
|
||
|
||
* breakpoint.c (bpstat_stop_status): Further explorations of
|
||
watchpoints and why things don't work all the time.

|
||
|
||
* core.c (core_ops): add and install.
|
||
Allow core debugging without exec file.
|
||
|
||
* dbxread.c (free_and_init_header_files): Merge two fns.
|
||
(end_symtab): Free named symbol table when a new version comes in.
|
||
(read_dbx_symtab): Relocate all kinds of symbols with base
|
||
address. First step toward handling different text, data, bss
|
||
reloc.
|
||
(add_file_addr_command): Renamed add_file_command.
|
||
(add_file_command): Vector to remote handler.
|
||
Add "load" as an alias for "add-file" command.
|
||
|
||
* defs.h: Allow "volatile" to be used in non-ANSI; use it for
|
||
non-returning functions.
|
||
|
||
* exec.c: Add exec_ops, and push it as a target when an exec
|
||
file is specified.
|
||
|
||
* infcmd.c (run_command): Pass executable file name and arg list
|
||
separately when starting an inferior. Permit "run" when no exec
|
||
file is specified, for VxWorks.
|
||
(detach_command): Move to child_detach in inftarg.c.
|
||
|
||
* inftarg.c: New file. Unix-child-specific routines, and the
|
||
child_ops structure.
|
||
|
||
* inferior.h (registers): Export "registers" as the way for
|
||
target dependent register handlers to find gdb's local copy of
|
||
the registers. Rename "stop_after_attach" to "stop_soon_quietly"
|
||
since it is now used by places that want wait_for_inferior to
|
||
handle the grunge but want to see every trap from the inferior.
|
||
|
||
* inflow.c (create_inferior): Pull out, and merge into infrun.c.
|
||
Eliminate remote_debugging hooks in terminal handling.
|
||
|
||
* infrun.c: Replace start_inferior with child_create_inferior.
|
||
Move all the hair of Unix shells and ptrace idiosyncracies into
|
||
child_create_inferior, so remote handlers don't have to deal.
|
||
Remove running_in_shell. Rename stop_after_attach to
|
||
stop_soon_quietly, and use it in a few other places where we want
|
||
to just call wait_for_inferior and get control back on the first
|
||
trap. trap_expected now never takes a value > 1.
|
||
(init_wait_for_inferior): Initialize static vars when a new
|
||
process is created.
|
||
|
||
main.c (gdbinit): Add new hook for .gdbinit file name, let
|
||
it be overridden by config files as GDBINIT_FILENAME.
|
||
(DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
|
||
Both of these are used for VxWorks gdb.
|
||
|
||
mcheck.c: rename include file "gmalloc.c" to avoid problems
|
||
with system include file "malloc.c".
|
||
|
||
param-no-tm.h: New include file, same as param.h but does not
|
||
include the default "tm.h" file. This is used in files where
|
||
the target is known, e.g. remote-eb.c or sparc-xdep.c.
|
||
|
||
param.h: Now just a shell that includes tm.h and param-no-tm.h.
|
||
|
||
remote-vx.c: New file, VxWorks remote debugging support. Uses
|
||
RPC routines that are shared with the target system, in directory
|
||
${srcdir}/vx-share.
|
||
|
||
remote.c: Vectorize remote interface.
|
||
|
||
source.c: Globalize source_path, and make an alias "l" for "list"
|
||
since we now have the "load" command.
|
||
|
||
sparc-xdep.c: Use new param-no-tm.h.
|
||
|
||
symmisc.c (free_named_symtab): Add new function from Wind River.
|
||
However, ifdef it out for now while we think about what it should
|
||
really be doing.
|
||
|
||
tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
|
||
PREPARE_TO_STORE to
|
||
the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
|
||
non-Unix-children handle this with their own code in the target
|
||
transfer vector.
|
||
|
||
Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
|
||
source and target lists. Add vx-share to default list of include
|
||
directories. Add new files to src and target lists: mem-break,
|
||
target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
|
||
${srcdir} versions of munch and createtags are used.
|
||
|
||
* valops.c (find_function_addr): Split out of call_function.
|
||
(call_function_by_hand): Rename call_function; this function
|
||
calls functions in the target by laboriously patching the target
|
||
word-by-word with the right stack, args, regs, etc.
|
||
|
||
|
||
Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
|
||
|
||
Handle AMD 29000 a bit better.
|
||
|
||
* remote-eb.c (readchar): Mask received char log to make it readable.
|
||
(remote_start): Pass arguments down to executing program.
|
||
Make startaddr unsigned.
|
||
infrun.c (start_inferior): Accept args, pass them to
|
||
remote_start.

||
infcmd.c (run_command): Pass args down to start_inferior.
|
||
|
||
* tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
|
||
the target object file format.
|
||
tm-29k.h: Pay heed to COFF_ENCAPSULATE.
|
||
|
||

|
||

|
||
|
||
* Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
|
||
* TODO: We did a few things, we have more to do though.
|
||
|
||
* xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
|
||
* inflow.c (inferior_died): Clear deferred stores.
|
||
|
||
* Debug problems with dummy frames and calls to the inferior.

|
||
* sparc-tdep.c (do_restore_insn): Simplify.
|
||
(sparc_frame_find_saved_regs): Simplify and fix what we find.
|
||
(sparc_push_dummy_frame): Simplify and fix what we push.
|
||
(sparc_pop_frame): Slightly more hair here, deciding whether
|
||
we are restoring a saved PC or returning to a return address in %i7.
|
||
* sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
|
||
|
||
* utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
|
||
* symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
|
||
* obstack.h (chunkfun): ditto.
|
||
* defs.h (xmalloc, xrealloc): ditto
|
||
|
||
* utils.c (quit): Grab the terminal from the child if necessary.
|
||
|
||
* inflow.c (term_status_command): Rename to term_info, change
|
||
to "info terminal".
|
||
|
||
* sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
|
||
(is_delayed_branch): Speed up.
|
||
* sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
|
||
Still missing some float ops, and needs testing.
|
||
|
||
* Support for input and output radixes other than base 10
|
||
* defs.h (input_radix, output_radix): Declare.
|
||
* expread.y (yyparse, parse_number): Handle changes of input
|
||
radix, and ambiguous names-or-numbers in radixes >10.
|
||
* printcmd.c (print_scalar_formatted): Print formatted hex
|
||
numbers in varying column widths.
|
||
* valprint.c (val_print): Use output_format to print scalar ints.

|
||
(set_output_radix): Set output_format from output_radix.
|
||
(_initialize_valprint): add `set radix' but leave the others off.

* main.c (execute_command): Let stupid questions be turned off.
|
||
(_initialize_main): Handle "set stupidity", etc.
|
||
|
||
* main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
|
||
sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
|
||
|
||
Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
|
||
|
||
* TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
|
||
bfd stuff is still screwed up, but with some manual work, it
|
||
compiles.
|
||
|
||
* breakpoint.c (bpstat_do_actions): Start over if a command
|
||
proceeds the inferior, since the inferior will have stopped and
|
||
will need to have its new stop-actions taken care of.
|
||
|
||
* dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
|
||
compiler fits, simplify it.
|
||
|
||
* gdb.texinfo (directory command): Doc new dir command.
|
||
source.c (directory_command): "dir" now puts things on the front
|
||
of the path, moves dups up front, and handles multiple names
|
||
on the command line, inserting each one in order. It also
|
||
blows away cached line and full_filename info.
|
||
|
||
* stack.c (backtrace_command): Skip "more stack frames follow"
|
||
unless interactive.
|
||
|
||
* Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
|
||
xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
|
||
xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
|
||
The only odd one was Gould NP1, which had defined vprintf to
|
||
"printf"!!!
|
||
|
||
* Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
|
||
printcmd.c (print_command_1): Pass 'inspect' flag down as a global
|
||
variable, inspect_it.
|
||
valprint.c (print_string, val_print): Use the global inspect_it
|
||
to indicate whether to print in Epoch style or normal style.
|
||
|
||
Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
|
||
|
||
* printcmd.c (call_command): add an alias for the "print" command
|
||
which runs expressions and doesn't print the result if void.
|
||
(print_command_1): implement it.
|
||
|
||
* command.c: Remove #if 0'd code. Initialize all the fields
|
||
in add_cmd (). Rename do_nothing_command to
|
||
not_just_help_class_command, and make it externally visible.
|
||
command.h: add user_commands to struct.
|
||
* main.c (define_command): Don't overload c->function with a char
|
||
string as well as a function pointer.
|
||
|
||
* eval.c (evaluate_subexp): Reinstall tiemann changes to
|
||
calling convention of value_struct_elt () that got dropped in
|
||
merge.
|
||
|
||
* tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
|
||
sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
|
||
|
||
* tm-sparc.h (POP_FRAME): replace some constants with defines.
|
||
|
||
* sparc-xdep.c (store_inferior_registers): defer stores to regs
|
||
until a good time (e.g. when we are about to run the child),
|
||
saving ptrace calls.
|
||
* infrun.c (proceed): handle DO_DEFERRED_STORES.
|
||
* tm-sparc.h: define DO_DEFERRED_STORES.
|
||
|
||
* sparc-xdep.c (store_inferior_registers): when storing float
|
||
registers, don't store stack regs too. When storing the SP,
|
||
however, DO store the stack regs too. This fixes a bug in which
|
||
the dummy frame is not recognized when a call_function finishes,
|
||
because its frame pointer (in the stack regs) was never
|
||
initialized.
|
||
(read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
|
||
even though we don't know how to read them from an inferior.
|
||
valops.c (call_function): Comment about storing SP.
|
||
|
||
* infrun.c (save_inferior_status): Save away the original bpstat
|
||
chain so it can be restored later. Install the copied version for
|
||
use by whoever saved the status. It will be blow away by
|
||
restore_inferior_status, and the original chain restored. This is
|
||
important for people who have pointers into the original.
|
||
|
||
* breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
|
||
findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
|
||
main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
|
||
|
||
|
||
Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
|
||
temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
|
||
Add stuff.c and kdb-start.c to the OTHERS list for tar files.
|
||
|
||
Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Merge Mike Tiemann's multiple inheritance changes from Sun.
|
||
Store the baseclasses in a type struct starting from array element
|
||
0 rather than from the unusual array element 1.
|
||
|
||
dbxread.c: the above.
|
||
(virtual_context): Add
|
||
Read new debug information about which virtual function table
|
||
a virtual function is from, and store it in fn_field.fcontext.
|
||
|
||
symtab.h: Add fcontextt. Fix baseclass indices. Typo in
|
||
TYPE_FN_FIELD_STATIC_P.
|
||
|
||
symtab.c: the above.
|
||
valops.c: the above. Handle pointer casts of object *'s.
|
||
(search_struct_method): Add.
|
||
(value_struct_elt): First arg is now a pointer to a value, and is
|
||
modified on return.
|
||
|
||
valprint.c: the above.
|
||
values.c (value_virtual_fn_field): Add type arg. Handle
|
||
offsetting to the proper object when calling virtual fns.
|
||
The above.
|
||
(baseclass_addr): Add valuep arg.
|
||
|
||
* README: Document the current state of BFD config (missing).
|
||
* TODO, ChangeLog, Makefile.dist: Roll version.
|
||
* WHATS.NEW: Add summary of changes since 3.5.
|
||
|
||
Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
|
||
|
||
* dbxread.c (read_struct_type): Clear bit vectors whenever
|
||
we allocate one.
|
||
symtab.c (B_CLRALL): define.
|
||
|
||
* tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
|
||
using == rather than =. Huh... This fixes the dreaded problem
|
||
wherein builtin_type_int becomes TYPE_CODE_FLT.
|
||
|
||
* core.c (info_files): Show the inferior pid.
|
||
|
||
* config.gdb: Avoid putting "dir" command into .gdbinit. GDB
|
||
already knows how to look in the source directory.
|
||
|
||
* Remove psymtab hair from many places. Remove duplicated code
|
||
for searching symbol tables. Hide psymtabs from most places.
|
||
Make it fast to get from a psymtab to its symtab.
|
||
|
||
blockframe.c (blockvector_for_pc): Remove psymtab hair.
|
||
coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
|
||
mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
|
||
dbxread.c: export psymtab_to_symtab, make it work if called N times.
|
||
(psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
|
||
new symtab completely. New psymtabs get symtab pointer
|
||
initialized to zero. Remove MI warning printf.
|
||
symtab.h: Comments. Add psymtab to symtab pointer.
|
||
(PSYMTAB_TO_SYMTAB): New macro.
|
||
symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
|
||
source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
|
||
compilation fields.
|
||
stack.c (backtrace_command): Avoid pre-pass to read symbols, if
|
||
verbose is not set.
|
||
(print_frame_info): Avoid special-casing symbols that have not yet

|
||
located the source file by its full name.
|
||
|
||
* symtab.c (lookup_symbol): Use find_pc_symtab rather than
|
||
find_pc_psymtab. When a name is found in the misc function
|
||
vector, search the symbol table for its mangled name, not the
|
||
name that the user typed.
|
||
|
||
* bfd.h: Fix missing comment terminators, make #endifs match.
|
||
|
||
* valarith.c (value_less): Handle unsigned int comparisons.
|
||
Add FIXME about pointer compares, which assume host and target
|
||
pointers are the same.
|
||
|
||
* command.c (do_nothing_command): lint
|
||
dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
|
||
fix comments on debug symbol format for visibility. Actually set
|
||
visibility of symbols.
|
||
main.c (echo_command): lint; use <readline/history.h>.
|
||
tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
|
||
obstack.h (_obstack_blank): Rearrange pointer math to avoid
|
||
pointing past end of allocated memory; saber complains.
|
||
obstack.h: Declare the external functions that we use.
|
||
valarith.h: use <string.h>
|
||
solib.c (solib_add): lint.
|
||
|
||
Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
|
||
|
||
* main.c (initialize_main): Default info_verbose to off, now that
|
||
symbol reading is fast.
|
||
(quit_command): Avoid clobbering exec_bfd while quitting.
|
||
|
||
* Initial BFD (binary file diddling library) merger:
|
||
coffread.c: Change AOUTHDR to struct exe_hdr.
|
||
dbxread.c: ditto.
|
||
core.c: initialize initialized data at compile time.
|
||
(core_file_command): Move from coredep.c, convert to bfd.
|
||
(xfer_core_file): Convert to bfd.
|
||
exec.c (exec_file_command): use bfd routines.
|
||
gdbcore.h: BFD.
|
||
mips-tdep.c: Remove exec_file_command and friends.
|
||
source.c: bfd.
|
||
|
||
* coredep.c: (fetch_core_registers) Convert core_file_command to
|
||
fetch_core_registers.
|
||
mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
|
||
|
||
* utils.c: (error): Bogus crap, FIXME, to print bfd errors.
|
||
(my_bfd_read): More bogosity, which I don't think we call.
|
||
(program_name): Remove this atrocity asap!
|
||
|
||
Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
|
||
|
||
* From Per Bothner:
|
||
values.c: allocate_repeat_value was not clearing the
|
||
optimized_out field.
|
||
(value_static_field): minor stylistic fix (wrong macro was used).
|
||
valops.c (value_struct_elt_for_address): didn't work for C++
|
||
static fields.
|
||
|
||
* signame.c (_initialize_signame): Initialize signal names once.
|
||
|
||
* breakpoint.h, command.c, copying.awk, defs.h, environ.c,
|
||
exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
|
||
symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.

|
||
|
||
* tconfig/sun3os4: Remove warning about native assembler,
|
||
since it also occurs in the xconfig file.
|
||
|
||
* findvar.c (registers): Allocate some slop after `registers'
|
||
to prevent stray accesses from trashing the next variable.
|
||
|
||
* tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
|
||
on the sun-3, by changing the #ifdef from `sun3' (which is not
|
||
defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
|
||
vars, which happened to follow `registers' in the executable.
|
||
|
||
* readline/history.c (history_search): Heed gcc-2's advice
|
||
and parenthesize && inside ||).
|
||

|
||
|
||
* infrun.c (wait_for_inferior, at end): Don't set up
|
||
prev_* if the inferior no longer exists.
|
||
|
||
* inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
|
||
CANNOT_EXECUTE_STACK.
|
||

|
||
|
||

|
||
infrun.c (wait_for_inferior, 2 places): Use it.
|
||
|

|
||
|
||
* Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
|
||
right thing for remote-eb.c.
|
||
|
||
* sun3-xdep.c: Remove extraneous call to remote_store_registers.
|
||
* sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
|
||
|
||
* blockframe.c: Put get_frame_saved_regs inside #if !defined
|
||
(FRAME_FIND_SAVED_REGS).
|
||
|
||
* findvar.c ({fetch,store}_registers): Check for
|
||
REMOTE_{FETCH_STORE}_REGISTER macro.
|
||
|
||
* findvar.c (get_saved_register): Add argument lval and
|
||
change meaning of argument addr.
|
||
findvar.c: Change calls to get_saved_register to reflect
|
||
new calling convention.
|
||
valops.c (value_assign): Use get_saved_register instead of
|
||
find_saved_register.
|
||
|
||
Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
|
||
|
||
* coffread.c (read_one_sym): Make temp_aux an AUXENT, not
|
||
an (uninitialized) pointer to one. Use "&" when passing it
|
||
to fread.
|
||
|
||
Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
|
||
|
||
* coffread.c (getfilename): Use DGUX x_offset and x_name if
|
||
defined.
|
||
|
||
* coffread.c (symbol_file_command): Put semicolon after
|
||
"int from_tty".
|
||
Put safe_to_init_tdesc_context in #if defined (TDESC).
|
||
Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
|
||
coffread.c: #include <sys/stat.h>.
|
||
(read_coff_symtab): Typo: in_source_files -> in_source_file.
|
||
Add missing ')' in check for "lc%" and friends. Remove
|
||
extraneous '}'.
|
||
Declare read_one_sym() at top of file.
|
||
(read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
|
||
MC68WRMAGIC can have the same value without causing a duplicate
|
||
case.
|
||
|
||
Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Allow a Makefile to be built without building the
|
||
tm and xm file links that screw up builds in subdirectories.
|
||
This is done with `config.gdb none', then you can do things
|
||
like `make gdb.tar.Z'.
|
||
* tconfig/none: Config file for no target system
|
||
* xconfig/none: Config file for no host system
|
||
* config.gdb: If no TM or XM files are called out by the
|
||
host or target file, don't make links for them.
|
||
|
||
* cplus-dem.c: Add documentation.
|
||
|
||
* dbxread.c (read_ofile_symtab): Turn a fatal error into a
|
||
simple error, so the user's gdb doesn't crash due to some object
|
||
file problem (e.g. somebody is rebuilding the file out from under
|
||
gdb).
|
||
|
||
* printcmd.c (print_address_symbolic): demangle the symbol.
|
||
|
||
* Makefile.dist (OTHERS): Remove tdesc-lib because it has
|
||
Motorola copyrights in it. Make "make gdb.tar.Z" work.
|
||
(alldeps.mak): sort and uniq all results from this; duplicates
|
||
hose gdb.tar.Z link building. Remove RCS files from
|
||
tconfig and xconfig. Add config files for sun386. Add
|
||
a few odd files to OTHERS and HFILES.
|
||
|
||
Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Makefile.dist: Pull solib.c to tconfig/sun?os4.
|
||
Roll version number to 3.91.5. Make lint work in bindir.
|
||
|
||
* README: Document cross-debugging and new file structure.
|
||
|
||
* blockframe.c: Lint. Include "value.h" to declare read_register.
|
||
(find_pc_partial_function): remove duplicate line.
|
||
|
||
* command.h: Lint. Declare error_no_arg and dont_repeat.
|
||
|
||
* tm-news.h: Remove inadvertently duplicated stuff.
|
||
|
||
* mipsread.c: Remove cache_pc_function stuff, now done cleanly.
|
||
Clean up usage of misc_function_type. Declare some CORE_ADDRs.
|
||
|
||
* config.gdb: Allow `config.gdb host target' form. Clean
|
||
up previous change that printed bogus messages when you just said
|
||
`config.gdb'.
|
||
|
||
* core.c: #include "command.h" for lint.
|
||
* dbxread.c: lint
|
||
* eval.c: lint
|
||
* main.c: Remove some casts of enums. Lint.
|
||
* source.c: lint
|
||
* symtab.c: lint
|
||
* symtab.h: lint
|
||
* expread.y: lint
|
||
* valarith.c: lint
|
||
|
||
* printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
|
||
|
||
* sparc-tdep.c (isannulled): Take instruction as parameter, don't
|
||
read it from memory. This will allow us to save ptrace calls
|
||
eventually. Changed caller single_step too.
|
||
|
||
* sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
|
||
that we aren't going to use, saving many ptrace calls, especially
|
||
when watchpointing or single stepping. Use some #define's for
|
||
constants.
|
||
(store_inferior_registers): Ditto.
|
||
(core_file_command): Use some #define's for constants.
|
||
|
||
* tm-sparc.h: Add #define's for some register numbers, so we
|
||
can eliminate the use of random constants in sparc-xdep.c.
|
||
|
||
* stack.c (frame_command, print_frame_info, up_command,
|
||
down_command) Remove frame_changed, since it
|
||
causes a bug and doesn't seem to do anything useful. In some
|
||
places it was used as a flag, in others as a stack level (?).
|
||
|
||
* utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
|
||
default is to use the portable (vprintf) version rather than the
|
||
kludge version.
|
||
* xm-news.h (MISSING_VPRINTF): Add.
|
||
|
||
* valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
|
||
|
||
Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Remove stuff that forces -Bstatic linking of gdb, and warnings
|
||
about linking debugged programs -Bstatic in the sun?os4 config
|
||
files in tconfig and xconfig subdirectories.
|
||
|
||
* main.c (main): Remove unreached exit(0) now that we exit
|
||
via quit_command().
|
||
|
||
* Create TODO file for online bug list. There are too many
|
||
"little" bugs to keep track of on paper.
|
||
|
||
* Change Projects file to refer to bug-gdb@cygnus.com
|
||
rather than kingdon@ai.
|
||
|
||
Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Makefile.dist (VERSION): 3.91.4 now.
|
||
|
||
* symtab.c (init_misc_bunches): Rename from init_misc_functions.
|
||
(condense_misc_bunches): Add sanity check that misc_count is
|
||
the same as the number of symbols in the bunch.
|
||
|
||
* coffread.c: rename init_misc_bunches. Pass an argument
|
||
to condense_misc_bunches (a zero).
|
||
|
||
* dbxread.c (partial_symbol_file_read): Call init_misc_bunches
|
||
every time we are called; don't rely on our caller to do it.
|
||
(add_file): Remove call to init_misc_bunches.
|
||
|
||
* mipsread.c: Only warn, don't error, if unknown symbol types.
|
||
This keeps an old gdb from falling on its face if it sees newly
|
||
extended symbol info. Rename init_misc_bunches.
|
||
|
||
Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Merge in changes from Per Bothner for DECstations and other
|
||
MIPS stuff. The rest is Bothner speaking:
|
||
|
||
The next message is a merger of Alessando Forin's mips port with
|
||
mine. I've tried to use my good if biased judgment to get
|
||
the best of both. It *does* need testing.
|
||
|
||
Some of the changes are general, *not* mips-specific.
|
||
|
||
param.h:
|
||
Didn't believe in little-endian bit order.
|
||
There are still inconsistencies about whether flags
|
||
like BITS_BIG_ENDIAN are integer (#if ...) or
|
||
boolean (#ifdef ...). I tried to paper over them.
|
||
|
||
dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
|
||
Moved some misc_function code that was common to
|
||
{dbx,coff,mips}read.c to symtab.c.
|
||
In the process, I think I cleaned things up a bit.
|
||
At the same time, moved obsavestring and obconcat to symtab.c.
|
||
|
||
dbxread.c:
|
||
Removed obsolete condense_addl_misc_bunches (use
|
||
condense_misc_bunches(1) instead).
|
||
|
||
exec.c:
|
||
Needed to include <sys/dir>, at least on DECstations.
|
||
|
||
valops.c, mips-tdep.c, tm-mips.h:
|
||
Added PUSH_ARGUMENTS macro to support funny argument-pushing
|
||
conventions (when STACK_ALIGN is insufficient).
|
||
Needed on mips, where doubles need 8-byte alignment,
|
||
but ints only need 4.
|
||
|
||
mips-opcode.h:
|
||
Removed cruft that was not being used.
|
||
Merged in many fixes (most from Frank Yellin, fy@lucid.com).
|
||
|
||
mips-pinsn.c:
|
||
Print $ before register-names (I think that makes things a little
|
||
more consistent).
|
||
Never print two instructions, even if one delays.
|
||
Removed hex-disassemble set_cmd. (This is not mips-specific,
|
||
so I think the argument is whether it is generally worthwhile or not.
|
||
I'm inclined to think not, given how easy it is to
|
||
convert between radixes in gdb.)
|
||
|
||
mipsread.c:
|
||
This is basically Alessando's code.
|
||
It doesn't use obstacks; I changed it to use obstacks
|
||
in a few minor places where using malloc causes a
|
||
memory leak. (Probably, more places could/should be changed.)
|
||
I added record_misc_function where it was missing.
|
||
In symbol_file_command and add_file_command, I tried
|
||
to make the code consistent with more recent versions.
|
||
Minor sylistic changes in parse_procedure.
|
||
Make a .gdbinfo. psuedo-symbol point back to the real
|
||
procedure symbol (using the isym field).
|
||
|
||
mips-tdep.c:
|
||
This is basically from my port, but with a lot of details
|
||
and a number of routines merged in from Alessando's version.
|
||
I basically used my code "raw" backtrace (use heuristics
|
||
from the actual code, rather than symbol table info) - though
|
||
the idea is Alessandro's. I feel my code is a little cleaner
|
||
here, particularly in being a little more flexible, such as being
|
||
able to handle gcc-produced code (which it now can).
|
||
It also doesn't do frame caching (which is not useful
|
||
more recent gdb versions).
|
||
I also used my code for push_/pop_dummy, more or less.
|
||
I tried to incorporate AF's code for testing sigtramp
|
||
while backtracing; I probably got it wrong.
|
||
Added mips_print_register, which tries to scrunch as much
|
||
information as possible on a screen...
|
||
Removed the skip-prologue set_cmd. As with hex-disassemble (see
|
||
under mips-pinsn.c), I don't see anything mips-specific here,
|
||
and I don't see it being all that useful anyway.
|
||
|
||
tm-mips.h:
|
||
Added a $fp psuedo-reg distinct from $fp (nice for gcc).
|
||
Use more register names (rather than hard-cases numbers).
|
||
|
||
Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Hack up 3.90.11 changes:
|
||
|
||
* Makefile.dist (depend): parameterize $(GCC).
|
||
Add solib.c and solib.o.
|
||
(readline): Fix vpath for both absolute or relative SRCDIR.
|
||
|
||
* blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
|
||
Also, let the part I didn't understand at least compile so
|
||
I can test the rest. FIXME.
|
||
|
||
* dbxread.c: Fix thinko using strcmp.
|
||
(init_psymbol_list): declare static.
|
||
(partial_symbol_file_open): Comment cleanups better, avoid
|
||
cleaning up the string table since the caller will do that.
|
||
Move the stat for mod time into symbol_file_command, temporarily.
|
||
(There should be a mod time for each symbol file, eventually,
|
||
to control its rereading. FIXME.)
|
||
|
||
* infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
|
||
SunOS, which gives error for shared libs otherwise. (From
|
||
Schaefer, probably FIXME needs work for portability.)
|
||
|
||
* solib.c: Move #include "param.h" to work.
|
||
Lowercase all the Uppercase Letters In the Messages.
|
||
(find_solib): Clean up inferior_so_name for debug printouts.
|
||
Allow no argument, to mean all shared libraries.
|
||
|
||
* symmisc.c: include param.h to get CLEAR_SOLIB.
|
||
|
||
Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Merge in Kingdon's changes from FSF: the diffs from 3.90.9
|
||
to 3.90.11. ChangeLog entries below are from this.
|
||
|

||
Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|

* Version 3.90.10.
|
||
|

|
||
|
||
Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
|
||
|
||

Put parens around gcc_p in expansion.
|
||
|
||
Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
|

|
||
* utils.c (lines_to_list): Return 10 if lines_per_page == 0.
|
||
|
||
Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|
||
|
||

blockframe.c (find_pc_partial_function): If a non-text symbol
|
||
is found, set *address = pc - FUNCTION_START_OFFSET.

|
||
Disable breakpoints instead of giving an error.
|
||
source.c (select_source_symtab): Initialize cs_pst.
|
||
symmisc.c: Call CLEAR_SOLIB if defined.
|
||
symtab.h: Make text{low,high} CORE_ADDR not int.
|
||
(psymtab): New field addr.
|
||
solib.c: New file.
|
||
dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
|

(record_misc_function): Give correct type for N_DATA symbols.
|

(condense_misc_bunches): do "misc_function_count = j" regardless
|
||
of inclink.
|
||
Take code which is shared between symbol_file_command and
|
||
add_file_command and put it into partial_symbol_file_{open,read}.
|
||
Split add_file_command into add_file_command and add_file.
|
||
Make psymtab_to_symtab read in the string table if the file
|
||
is not symfile.
|

Two new parameters to read_dbx_symtab and start_psymtab.
|

tm-sunos.h: New file.
|
||
|
||
Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|
||
|
||
* infcmd.c: Change cont_command to continue_command and "cont"
|
||
to "continue".
|
||
|
||
Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|
||
|
||
* breakpoint.c (enable_breakpoint): Get value of watchpoint.
|
||
|
||
* defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
|
||
|
||
* values.c (USE_STRUCT_CONVENTION): Check for structures of
|
||
size 1,2,4,8 rather than size < 8.
|
||
|
||
* dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
|
||
as necessary, not just once.
|
||
|
||
* sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
|
||
|
||
Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|
||
|
||
* {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
|
||
|
||
* tm-news.h: Add CALL_DUMMY_*.
|
||
|
||
* tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
|
||
|
||
* config.gdb: In list_host, list_target, use ${i}, not $i.
|
||
|
||
Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|
||
|
||
* source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
|
||
|
||
* sparc-opcode.h: Change all store floating-point state register
|
||
instructions to have the right match & lose fields.
|
||
|
||
Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
|
||
|
||
* Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
|
||
VPATH to readline.
|
||
config.gdb: If srcdir != ., create readline directory and
|
||
copy a makefile into it.
|
||
|
||
* wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
|
||
consistency with POSIX.
|
||
|
||
* breakpoint.c (bpstat_stop_status): Disable watchpoint
|
||
when we exit its exp_valid_block.
|
||
|
||
Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Makefile.dist: Bump version to 3.91.3.
|
||
|
||
* Clean up handling of breakpoint commands (somewhat).
|
||
Prompted by Tiemann bug report "cont 10" doesn't work any more.
|
||
|
||
inferior.h: Add breakpoint_proceeded to inferior status struct
|
||
and globals; save it and restore it.
|
||
(clear_breakpoint_commands): Cleanup, remove old #define.
|
||
|
||
infrun.c (clear_proceed_status): Set breakpoint_proceeded.
|
||
(save_inferior_status, restore_inferior_status): handle it also.
|
||
(proceed): Remove earlier code that set breakpoint_proceeded.
|
||
It is now set only in clear_proceed_status.
|
||
(clear_proceed_status): Cleanup, use bpstat_clear rather
|
||
than clear_breakpoint_commands. No callers need the stop_bpstat
|
||
between clear_proceed_status and proceed.
|
||
|
||
infcmd.c: Add breakpoint_proceeded definition and comment.
|
||
(cont_command, jump_command, signal_command): Move call to
|
||
clear_proceed_status right next to call to proceed.
|
||
|
||
breakpoint.c (bpstat_do_actions): Avoid clobbering our
|
||
caller's argument while running down the chain of breakpoints.
|
||
Use new variable "breakpoint_proceeded" to determine when
|
||
a command that it executes moves the inferior past the
|
||
breakpoint.
|
||
(bpstat_clear): Handle NULL argument.
|
||
(bpstat_clear_actions): Avoid useless call to
|
||
breakpoint_auto_delete.
|
||
(delete_breakpoint): Clean up bpstat's that are pointing to
|
||
the deleted breakpoint from the stop_bpstat chain.
|
||
(breakpoint_auto_delete): Simplify.
|
||
|
||
* Clean up handling of EOF, error on stdin, etc. This was
|
||
prompted by a network problem that caused gdb to go into an
|
||
infinite loop filling up its malloc'd memory.
|
||
|
||
main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
|
||
not clear_breakpoints_commands, which is now gone.
|
||
(main): If command_loop returns (e.g. from EOF on stdin), do
|
||
a quit_command (looping back to command_loop if quit_command
|
||
doesn't really quit).
|
||
(command_loop): check result from command_line_input and
|
||
exit if it returns NULL, rather than passing the NULL to
|
||
execute_command.
|
||
(gdb_readline): Free malloc'd result space before returning
|
||
NULL for EOF.
|
||
|
||
* utils.c (query): Handle C-d to mean "yes", just as if the
|
||
input was not a terminal. Also avoid infinite loop if EOF
|
||
occurs in mid-input-line before newline. This allows
|
||
query to be used at EOF on stdin with reasonable results.
|
||
|
||
* infrun.c (proceed): Set breakpoint_proceeded.
|
||
|
||
* values.c (value_as_long): Avoid infinite recursion for enums.
|
||
(_initialize_values): Fix typo in help msg (kingdon).
|
||
|
||
* Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
|
||
RL_LIB for linking. This allows -lreadline for linking
|
||
and nothing for dependencies, once readline is a real library.
|
||
|
||
* config.gdb: Jim Kingdon: give useful error message if the
|
||
host or target type is not recognized.
|
||
|
||
* defs.h (alloca): SPARC <alloca.h> does not declare alloca,
|
||
it just defines it. Dumb, but deal with it.
|
||
|
||
* Jim Kingdon suggests:
|
||
in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
|
||
|
||
Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Makefile.dist (VERSION): Bump version # to 3.91.2.
|
||
|
||
* Clean up Bothner's changes.
|
||
|
||
* blockframe.c (clear_pc_function_cache): New function.
|
||
* blockframe.c: remake cache_pc_function_* static.
|
||
* dbxread.c (symbol_file_command): remove references to
|
||
cache_pc_function_* variables.
|
||
* dbxread.c (read_struct_type): Use VOFFSET_STATIC.
|
||
* printcmd.c: Avoid kludging a global variable (addressprint)
|
||
to avoid printing the address of a string twice. Instead,
|
||
pass the format letter 's' down low enough that it can be seen
|
||
to avoid this problem.
|
||
(print_formatted): Pass format arg to value_print.
|
||
(restore_addressprint): Remove function.
|
||
(do_examine): Avoid hacking addressprint, cleanups and such.
|
||
(print_frame_args): Add a comment to a Bothner change.
|
||
* symtab.h: define VOFFSET_STATIC and use it instead of "-1".
|
||
* symmisc.c (free_all_symtabs): Call clear_pc_function_cache
|
||
to wipe out the values cached in blockframe.c.
|
||
* symtab.c (find_method): Add comment saying how big you must
|
||
allocate to be "big enough". Per being terse again.
|
||
* valprint.c (val_print): Handle format letter "s" to print
|
||
strings without addresses. Add comment to vtbl printing code
|
||
which casts with wild abandon. Rearrange reference-printing
|
||
code so it prints:
|
||
@0xaddr: value (print w/addressprint)
|
||
value (print w/~addressprint)
|
||
@0xaddr (parameter lists w/addressprint)
|
||
or nothing (parameter lists w/o addressprint)

Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
|
||
|
||
* Merge more changes from Per Bothner:
|
||
|
||
Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
|
||
annoying) that I tried to improve it. Here are my suggestions.
|
||
|
||
These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
|
||
|
||
findvar.c:
|
||
Do automatic de-reference when taking the address of a reference.
|
||
printcmd.c:
|
||
Don't deref_ref when printing parameter lists.
|
||
valops.c:
|
||
More attempts at treating refernences properly.
|
||
valprint.c:
|
||
In val_print, if deref_ref==0, don't print dangling " = ".
|
||
value.h:
|
||
Add COERCE_REF macro, which de-references an REF.
|
||
|
||
* Merge changes from Per Bothner:
|
||
|
||
* Fixed (Sony news)-specific configuration problems.
|
||
* Fixed other problems with using vanilla pcc and libc (enum problems;
|
||
assumption that vsprintf exists).
|
||
* Some major speed-ups (finc_pc_partial_function now caches a match;
|
||
parsing avoids duplicate symbol_lookup calls).
|
||
* Changed handling of baseclasses (no longer use baseclasses field
|
||
of struct type, use the first n_baseclasses fields instead).
|
||
* Various minor changes/fixes, most C++-related.
|
||
|
||
blockframe.c:
|
||
Cache the most previous match from find_pc_partial_function.
|
||
(Save both low and high ends of matching function's pc range.)
|
||
This speeds up the loop of infrun.c:wait_for_inferior quite
|
||
a bit, and makes step/next commands much zippier.
|
||
command.c:
|
||
Added an enum->int cast (otherwise, some compilers barf).
|
||
dbxread.c:
|
||
No longer set baseclass offset to 0, since multiple
|
||
inheritance now mostly works.
|
||
Added a number of casts, to shut up compiler warnings
|
||
(after stabs where made enums, not ints).
|
||
When discarding a symbol table (in symbol_file_command),
|
||
must clear the cache introduced in blockframe.c.
|
||
Don't convert $vtbl_ptr_type to vtbl any more.
|
||
Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
|
||
Mask off sign bit emitted by g++ for virtual table offset.
|
||
Set voffset to -1 (not 1) for static member functions.
|
||
expread.y:
|
||
Changed parsing/lexing of names to avoid doing symbol lookup twice
|
||
(once when lexing to determine symbol class, once for real).
|
||
Now only call symbol_lookup once. Fields of 'this' win especially big.
|
||
printcmd.c:
|
||
Subpress printing addr twice in the case of 'x/s addr'.
|
||
symtab.c:
|
||
lookup_basetype_type is no longer used.
|
||
Add find_methods as recursive helper function to decode_line_1.
|
||
This allows multiple inheritance to work.
|
||
Also, once one or more matches has been found, do not look in
|
||
base-classes. (Baseclass methods would be overridden, anyway.)
|
||
symtab.h:
|
||
Removed baseclasses array in struct type.
|
||
Instead of using baseclasses[i], use fields[i-1].
|
||
Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
|
||
Changed sign convention of voffset (previous was inconsistent).
|
||
tm-news.h:
|
||
Some macros (CALL_DUMMY and relatives) were missing. Put them back.
|
||
utils.c:
|
||
Used to assume existence of vsprintf. Re-written to not need it
|
||
if HAVE_VPRINTF is undefined.
|
||
valops.c:
|
||
typecmp was too pessimistic. Made it less so.
|
||
valprint.c:
|
||
Don't print space after address.
|
||
If vtable points to a misc symbol (with 0 offset), print it,
|
||
since that indicates the actual class of the object.
|
||
Changed ype_print_derivation_info to use new inheritance
|
||
scheme (without baseclasses vector).
|
||
values.c:
|
||
In value_primitive_field, fixed some bugs left over from previous set of fixes.
|
||
Also, changes needed because TYPE_BASECLASSES were removed.
|
||
xm-news.h:
|
||
REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
|
||
|
||
Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
|
||
|
||
* source.c:
|
||
If there is no path set, and the symbols don't indicate what directory
|
||
a file was compiled in, look in the current directory. But either
|
||
a path or a known compilation directory will prevent this.
|
||
|
||
* dbxread.c:
|
||
Three independent bug fixes:
|
||
* Remove the #if 0 block that breaks some stuff.
|
||
* SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
|
||
adapt gdb to either SunOS 4.0.* or 4.1.
|
||
* MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
|
||
|
||
* symtab.c:
|
||
Instantiate the class T when looking for methods in it. (Tiemann@sun)
|
||
|
||
* valprint.c:
|
||
(type_print) Demangle the name being printed.
|
||
(type_print_base) Handle botched demangling without coredump (tiemann).
|
||
|
||
* values.c:
|
||
(check_stub_method): Document routine.
|
||
(tiemann) fix bug for no-arg functions
|
||
Avoid clobbering beyond end of malloc'd storage.
|
||
Terminate the argument list properly.
|
||
|
||
Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
|
||
|
||
* Changes merged by John Gilmore:
|
||
|
||
breakpoint.c:
|
||
In breakpoint_1, use new print_address_symbolic instead
|
||
of find_pc_partial_function. (This forces use of assembler-level
|
||
addresses, and avoids misleading non-mangled source-level names.)
|
||
cplus-dem.c:
|
||
Generalize ansi argument such that -1 means skip arglist totally.
|
||
Removed global variable print_ansi_qualifiers (which made
|
||
code non-reentrant), in favor of extra explicit arguments
|
||
to internal routines.
|
||
printcmd.c:
|
||
Add new helper function print_address_symbolic.
|
||
Use find_pc_misc_function instead of find_pc_partial_function
|
||
(since we want assembler-level symbols here).
|
||
stack.c:
|
||
Print unknown function as just "f (...)", not "f (...) (...)".
|
||
Use new fputs_demangled explicitly.
|
||
symtab.c:
|
||
Fixed a typing violation (problem: value.h cannot be imported
|
||
without renaming many variable in this file).
|
||
lookup_symbol: If no matching misc_func, look for a C++-mangled name.
|
||
decode_line_1: Moved forward some never-reached code.
|
||
Made decode_line_2 skip function prologues correctly.
|
||
utils.c:
|
||
fputs_filtered should not demangle by default.
|
||
Add new fputs_demangled to demangle on demand..
|
||
valops.c:
|
||
Change value_struct_elt to use value_primitive_field (using recursive
|
||
utility function search_struct_field). This allows foo.bar to work
|
||
for multiple inheritance (so far only for data fields).
|
||
Change check_field in the same way (recursive helper function
|
||
to support multiple inheritance).
|
||
(Note: there are more of these problems that I haven't fixed.
|
||
Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
|
||
value_of_this: 'this' symbol name is now just "this", note "$this".
|
||
valprint.c:
|
||
Don't print static members.
|
||
Avoid printing "members of <type>" if there are none.
|
||
Simplified type_print_derivation_info by merging duplicate code.
|
||
Remove useless blank lines in type_print_base (ptype command).
|
||
value.h:
|
||
Added declaration of new routine value_primitive_field.
|
||
values.c:
|
||
Added value_primitive_field which is generalized version of
|
||
value_field that can handle multiple inheritance (non-zero offsets etc).
|
||
Re-implemented value_field to call value_primitive_field.
|
||
|
||
Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
|
||
|
||
* infcmd.c -- insert else to avoid 'delete env' coredump when you
|
||
delete the whole environment. Karl Berry reported the bug.
|
||
* source.c - fix openp to avoid //'s in filenames, which
|
||
trigger an Emacs bug causing it to not be able to find files
|
||
when running gdb in a window.
|
||
* dbxread.c - zap the #if 0 that botches the add-file code.
|
||
It seems to work a lot better without all the code commented out.
|
||
|
||
Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Merge Tiemann's and Ted Goldstein's changes, detailed below,
|
||
into gdb-3.90.9.
|
||
|
||
Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
|
||
|
||
* Makefile - added a ${CFLAGS} to a couple of entries,
|
||
added remote-sa.sparc.c
|
||
* added remote.sa-sparc.c, a modification of remote.c
|
||
which conducts a dialog directly with the SparcStation prom.
|
||
* breakpoint.c, infrun.c, sparcdep.c added
|
||
remote_insert_breakpoint(), and remote_remove_breakpoint()
|
||
to breakpoint.c instead of directly writing breakpoint instructions.
|
||
* sparcdep.c on remote_debugging,there is no need
|
||
to remove signle step breakpoint instructions.
|
||
* main.c added "-epoch" flag and "int epoch_interface" to main.c
|
||
global variable
|
||
* printcmd.c - epoch interface sends lisp expressions to open up
|
||
epoch windows on inspection.
|
||
* valprint.c - added arrayprint, and addressprint and made adding
|
||
format controls easier
|
||
* wait.h added a couple of undef's because we were getting
|
||
complaints about WSTOPSIG and WTERMSIG begin redefined.
|
||
|
||

||
|
||
* values.c (baseclass_addr): Run loop from INDEX+1 to

|
||
|
||
* cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
|
||
should print ANSI qualifiers (such as `const' and `volatile').
|
||
All callers changed to call with ANSI == 1, except from
|
||
`check_method_stub', which uses old-style syntax.
|
||
|
||
* symseg.h (struct fn_field): Remove unneccessary `args' field.
|
||
* symtab.h (TYPE_FN_FIELD_ARGS): Redefined.

|
||
* values.c (check_stub_method): New function.

|
||
|
||
Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
|
||
|
||
* breakpoint.c (catch_command): New function. Provides a
|
||
mechanism to set breakpoints based on catch clauses.
|
||
(disable_catch): Similar, but disables breakpoints on catch
|
||
clauses.
|
||
(delete_catch): Similar, but deleted breakpoints on catch clauses.
|
||
|
||
Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
|
||
|
||
* blockframe.c (blockvector_for_pc): New function.
|
||
* blockframe.c (block_for_pc): Changed to call
|
||
`blockvector_for_pc' and get the block itself.
|
||
|
||
* stack.c (catch_info): New function. Prints info about
|
||
exceptions which can be caught in the current frame.
|

* stack.c (print_frame_label_vars): New function. Similar to
|
||
`print_frame_local_vars'.
|
||
* stack.c (print_block_frame_labels): Prints out labels that are

defined in this frame. These labels are exceptions that can be
|
||
caught.
|
||

|
||
|
||
Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
|
||
|
||
* valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
|
||
form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
|
||
when printing the type.
|
||
|
||
Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
|
||
|
||
* valprint.c (val_print): Use `baseclass_addr' to access the
|
||
baseclasses pointed to via the derived class object at VALADDR.
|
||
|
||
* values.c (baseclass_addr): New function. Casts derived pointers
|
||
to baseclass pointers taking virtual baseclasses and multiple

also check step_resume_breakpoint.
|
||
Insert breakpoints and continue (not step) if
|
||
step_resume_break_address != NULL, even if another_trap.
|
||
If trap_expected and we enter sigtramp, then set up a
|
||
step_resume_break.
|
||
If trap_expected is set when we hit the step_resume_break,
|
||
set another_trap.
|
||
When calling resume and trap_expected says tell resume to step
|
||
(2 places), also check step_resume_break_address.
|
||
|
||
* infrun.c (wait_for_inferior): Don't set

|
||
instead of stuffing things in buffers (oappend, etc).

* breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
|
||
execute_command, exit both loops.
|
