mycroft b74cbfe5ed Eliminate signed-unsigned comparisons. 1997-09-09 18:59:23 +00:00
thorpej f576b48b39 Make sure debugging symbol sections are aligned. 1997-09-05 21:46:59 +00:00
thorpej 5accaea913 Add support for Elf symbol tables to DDB, written from scratch by me. 
Known to work in DDB under NetBSD/alpha.
 1997-07-01 18:36:36 +00:00
thorpej 9ec5f78d39 Pass the current DDB symbol table to X_db_symbol_values(). 1997-06-26 01:19:07 +00:00
thorpej d9f8d88a35 Fixup the software single-step code (used on architectures where there 
is no hardware support for single-stepping):
- Fix branch prediction and delay slot computation (for the MIPS).
- Correctly deal with branch taken vs. branch not taken cases, and
  self-branches.
- General cleanup, including types botches.
Partially from Mach 3, with a bunch of cleanup work by me.
 1997-06-26 01:18:11 +00:00
thorpej 1d7e4d35d9 Update prototypes for new function signatures. Note, the ddb_init() 
signature is currently different for the DB_AOUT_SYMBOLS vs. the
DB_ELF_SYMBOLS cases. (XXX)
 1997-06-26 01:14:16 +00:00
thorpej 84c0797eda Use db_expr_t rather than int when reading a value from the kernel 
address space, to avoid type-size problems.
 1997-06-26 01:13:11 +00:00
thorpej 0ae10b0d60 In the db_breakpoint_t, use a db_expr_t to store the original instruction, 
not an int.
 1997-06-26 01:12:05 +00:00
thorpej 76fbbf772d A few small changes to make it easier to support non-a.out symbol table 
formats in DDB:
- Reverse the sense of the symbol format #ifdef... i.e. instead of
  "#ifndef DB_NO_AOUT", use "#ifdef DB_AOUT_SYMBOLS".  This is pulled
  in from <machine/db_machdep.h>.
- Change the signature of X_db_sym_init().  Instead of int * and char *,
  it now takes void *'s for the start and end of the symbol table.
- In X_db_sym_init(), check that the pointer to the beginning of
  the symbol table is aligned.
- X_db_symbol_values() now takes a "db_symtab_t *symtab" argument.
 1997-06-26 01:11:00 +00:00
thorpej c95e0b0782 Use db_expr_t rather than int in a few strategic places to avoid 
type-size problems.

gwr 8ae8b46853 Add db_kill_proc(). 1997-05-07 18:50:50 +00:00
gwr ea3925f508 FIXUP_PC_AFTER_BREAK now takes an arg of type db_regs_t * 1997-02-06 21:16:28 +00:00
cgd a9295bf811 make variable pointers (in variable declaration structs) be 'long *', so 
that the common case can be handled with no hassles on all machines.
fix up the various internal variables which are also exported via sysctl
(and which therefore must be 'int's) to do the right thing via a special
read/write function.

thorpej c14ce368af Define db_onpanic variable; if non-zero, the DDB will be entered when 
the kernel panics.  It may be initialized to 0 with the kernel option
"DDB_ONPANIC=0", and is patchable.  It may be changed at run-time
from within the DDB (as a DDB variable) or via the ddb.onpanic sysctl
node.

Export all DDB built-in variables via sysctl.

cgd 34829de7f9 change more __kprintf__ format attributes to use __kprintf_attribute__, 
rather than just __attribute__, so they can be #defined out on non-NetBSD
versions of gcc.

christos b4a31b1fc7 Kernel version of longjmp() does not take the return value of setjmp() as 
an argument. setjmp() always returns 1.

gwr 21a1e8e747 When use default form when printing location (i.e. after step).
