I removed the XMM6/7 registers from the register list because they are not used
on Win64 however they are necessary for parameter passing on x86-64. I have now
restored them but not marked them with RC_FLOAT so they will not be used except
for parameter passing.
Modified tcctest.c so that it uses 'double' in place of 'long double'
with MinGW since this is what TCC does, and what Visual C++ does. Added
an option -norunsrc to tcc to allow argv[0] to be set independently of
the compiled source when using tcc -run, which allows tests that rely on
the value of argv[0] to work in out-of-tree builds.
Also added Makefile rules to automatically update out-of-tree build
Makefiles when in-tree Makefiles have changed.
Define __STDC_HOSTED__ to one as the correct values should be either 1
or 0. Since tinycc is hosted, it should be set to 1.
Thanks Christian Jullien for the report.
Quoting Michael Matz on tinycc-devel:
"__STDC_HOSTED__ : not set (incorrectly, it should probably be set to 1
given that tcc assumes a normal main() and that the
rest of the provided facilities is provided by the C
library not under tcc control)"
- add quotes: eval opt=\"$opt\"
- use $source_path/conftest.c for OOT build
- add fn_makelink() for OOT build
- do not check lddir etc. on Windows/MSYS
- formatting
config-print.c
- rename to conftest.c (for consistency)
- change option e to b
- change output from that from "yes" to "no"
- remove inttypes.h dependency
- simpify version output
Makefile:
- improve GCC warning flag checks
tcc.h:
- add back default CONFIG_LDDIR
- add default CONFIG_TCCDIR also (just for fun)
tccpp.c:
- fix Christian's last warning
tccpp.c: In function ‘macro_subst’:
tccpp.c:2803:12: warning: ‘*((void *)&cval+4)’ is used uninitialized
in this function [-Wuninitialized]
That the change fixes the warning doesn't make sense but anyway.
libtcc.c:
- tcc_error/warning: print correct source filename/line for
token :paste: (also inline :asm:)
lddir and multiarch logic still needs fixing.
This replaces -> use instead:
-----------------------------------
- tcc_set_linker -> tcc_set_options(s, "-Wl,...");
- tcc_set_warning -> tcc_set_options(s, "-W...");
- tcc_enable_debug -> tcc_set_options(s, "-g");
parse_args is moved to libtcc.c (now tcc_parse_args).
Also some cleanups:
- reorder TCCState members
- add some comments here and there
- do not use argv's directly, make string copies
- use const char* in tcc_set_linker
- tccpe: use fd instead of fp
tested with -D MEM_DEBUG: 0 bytes left
tests/Makefile:
- print-search-dirs when 'hello' fails
- split off hello-run
win32/include/_mingw.h:
- fix for compatibility with mingw headers
(While our headers in win32 are from mingw-64 and don't have
the problem)
tiny_libmaker:
- don't use "dangerous" mktemp
Should fix some warnings wrt. access out of array bounds.
tccelf.c: fix "static function unused" warning
x86_64-gen.c: fix "ctype.ref uninitialzed" warning and cleanup
tcc-win32.txt: remove obsolete limitation notes.
Also:
- fix "make tcc_p" (profiling version)
- remove old gcc flags:
-mpreferred-stack-boundary=2 -march=i386 -falign-functions=0
- remove test "hello" for Darwin (cannot compile to file)
This replaces commit 3d409b0889
- revert old fix in libtcc.c
- #include_next: look up the file in the include stack to see
if it is already included.
Also:
- streamline include code
- remove 'type' from struct CachedInclude (obsolete because we check
full filename anyway)
- remove inc_type & inc_filename from struct Bufferedfile (obsolete)
- fix bug with TOK_FLAG_ENDIF not being reset
- unrelated: get rid of an 'variable potentially uninitialized' warning
TCCs make dependency generator is incompatible with the GNU
depcomp script which is widely used. For TCC it has to go over
the output of -MD, (it detects it as ICC compatible), but the
sed commands it uses are confused by tabs in the output, so that
some rewrites aren't done.
Those tabs will then finally confuse make itself when the
generated .d files are included. It reads them as goal commands
(leading tab), and is totally lost then.
Short of changing depcomp (hard because distributed with all kinds
of software), simply emit spaces for -MD.
This matters when sizeof is directly used in arithmetic,
ala "uintptr_t t; t &= -sizeof(long)" (for alignment). When sizeof
isn't size_t (as it's specified to be) this masking will truncate
the high bits of the uintptr_t object (if uintptr_t is larger than
uint).
ld support arguments to multiple-letter options being passed in two
ways:
* -opt=arg
* -opt arg
libtool generate command line of the second form. This commit add
support for the second form so that libtool works with tcc. The way it
is done is to concatenate all -Wl options into one and then pass it to
set_linker.
Modify tcc to accept convert full 64bits of specified text section
when converting on Win64. Write high bytes to the elf section address
as well. This allows creation of elf binaries located in offsets using
full 64 bit addresses.

Since commit 9b09fc3 ("Add support of asm label for functions",
05-09-2010) tcc has had the capability to rename functions at the
assembly level. This capability was subsequently used by commit
2596273 ("Add support for __REDIRECT_NTH needed with eglibc",
11-09-2010) to redirect long double functions on platforms which
did not support long double.
Here we add the companion macro __REDIRECT which is used (along
with __REDIRECT_NTH) in the glibc headers on Linux to support the
Large File API (when _FILE_OFFSET_BITS is set to 64).

This changeset attempts to fix a few problems when giving using
the high 32bits of a 64bit section offset. There are likely more
issues (or perhaps regressions) lurking in the muck here. In general,
this moves a few data type declarations to use uplong. Also, add
support for 64bit mingw32 building under cygwin. Because native
types are used for 64 bit offsets, this won't fix challenges with
cross compiling from 32bit -> 64bit.
Tested under cygwin, against binary compiled with
-Wl,-Ttext=0xffffff8000000000

- use {B} to substitute tcc_lih_path (instead of \b)
- expand CONFIG_TCC_CRTPREFIX in CONFIG_TCC_LIBPATHS
which fixes duplicate CONFIG_SYSROOT.
- put default CONFIG_SYSROOT ("") into tcc.h
- remove hack from commit db6fcce78f
because $(tccdir)/include is already in sysincludes
- configure: error out for unrecognized options.
- win32/build-tcc.bat: put libtcc into base dir where it will
find lib/include automatically, and build libtcc_test example.
--sysincludepaths=.. specify system include paths, colon separated"
Sets CONFIG_TCC_SYSINCLUDEPATHS
--libpaths=... specify system library paths, colon separated"
Sets CONFIG_TCC_LIBPATHS
--crtprefix=... specify location of crt?.o"
Sets CONFIG_TCC_CRTPREFIX
--elfinterp=... specify elf interpreter"
Sets CONFIG_TCC_ELFINTERP
Also the CONFIG_TCC_XXX were renamed to make them look
more consistent.
Also move the elf_interp definitions to tcc.h.
Add a --multiarch-triplet switch to configure. The switch will allow
files to be search for each default path in path/<triplet> and then
path.
Default paths handled that way:
- CONFIG_TCC_SYSINCLUDE_PATHS
- CONFIG_TCC_LIBPATH
- path to crt*.o
- path to libgcc_s.so.1
Path missing: elf interpreter path (will be handled in another commit)
This allows passing colon separated paths to
tcc_add_library_path
tcc_add_sysinclude_path
tcc_add_include_path
Also there are new configure variables
CONFIG_TCC_LIBPATH
CONFIG_TCC_SYSINCLUDE_PATHS
which define the lib/sysinclude paths all in one and can
be overridden from configure/make
For TCC_TARGET_PE semicolons (;) are used as separators
Also, \b in the path string is replaced by s->tcc_lib_path
(CONFIG_TCCDIR rsp. -B option)
This was already possible using
make NOTALLINONE=1
and is now the default.
To build as previously from one big source, use
make ONE_SOURCE=1
Cross compilers are still build from one source because using
separate objects requires separate build directories one per
platform which currently is not (yet) supported by the makefile.
We could probably use gnu-makeish target variables like
$(I386_CROSS): OUTDIR=build/i386
$(X64_CROSS): OUTDIR=build/x86-64
and so on ...
Also NEED_FLOAT_TYPES for arm-gen is removed. It was about
variables that are referenced from outside (libtcc, tccgen).
We could declare them in tcc.h (as with reg_classes) or have
them twice in arm-gen.c. I chose option 2.
* Rename tcc_split_path_components
* Move tcc_split_path below memory wrapper section
* Ident tcc_split_path by 4
* Remove prefix and suffix clutter in tcc_split_path
* Don't dereference beyond the end of the search paths string
Add the possibility to search headers in several subdirectories of
/usr/local/include and /usr/include. A possible use case would be for
tcc to search for headers in /usr/local/include/x86_64-linux-gnu,
/usr/local/include, /usr/include/x86_64-linux-gnu and /usr/include in
turn.
