- tests/Makefile:
fix commit de54586d5b
This hunk it unrelated to the other changes (which are about MacOSX).
It is not useful and partially wrong. Optional tests are meant to
stay optional, btest would work only for i386
- tcc.h:
fix commit c52d79605a by unknown
The message says it's for MINTW but the patch has obviously
no effect for MINGW (which defines __GNUC__). However the patch
seems useful for MSC which however needs _strto(u)i64 with underscore.
- Makefile:
fix commit 5280293d6b
Do not build tcc.o with -DONE_SOURCE because we finally build tcc
from tcc.o and libtcc.a/so
- remove redunant else branch
- zero-terminate linker_arg
- declare cstr_xxx as PUB_FUNC
(which are functions used in tcc.c but not in the libtcc API.
Useful for a tcc(.exe) that uses the libtcc.(so/dll))
- while at it, export PUB_FUNCs from dll

On x86_64 we need to extend the reg_classes array because load()
is called for (at least) R11 too, which was not part of reg_classes
previously.
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.

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.
This cleans up the mess from commit
8f98573658
and preceeding.
- make tcc -m64 work on windows
- execvp on windows returns 0 always, replace by spawnvp
- remove bizarre support for i386-win32-tcc -m64
This fixes a bug introduced in commit
8d107d9ffd
that produced wrong code because of interference between
0x10 bits VT_CONST and x86_64-gen.c:TREG_MEM
Also fully zero-pad long doubles on x86-64 to avoid random
bytes in output files which disturb file comparison.
--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.
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.
By default, tcc search libraries in /lib and /usr/local/lib while crt*.o
files are searched in /usr/lib and ld.so is searched in /lib.
Unfortunetely the path are hardcoded in source code. This patch allow
tcc to look in an other directory and also to look in extra directories.
It's then possible to make tcc search libraries in /lib/x86_64-linux-gnu
and /usr/local/lib/x86_64-linux-gnu while crt*.o files are searched in
/usr/lib/x86_64-linux-gnu and ld.so is searched in
/lib/x86_64-linux-gnu.
- Fix function assembly label mechanism introduced in commit
9b09fc376e to only accept alternative
name for function declaration.
- merge the code with the one introduced in commit
264a103610.
- Don't memorize token for asm label but directly the asm label.
Implement C99 Variable Length Arrays in tinycc:
- Support VLA with multiple level (nested vla)
- Update documentation with regards to VT_VLA
- Add a testsuite in tcctest.c
