- 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
See also commit 9527c4949f
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.
- 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.
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)
Basically, with:
typedef __attribute__((aligned(16))) struct _xyz {
...
} xyz, *pxyz;
we want the struct aligned but not the pointer.
FIXME: This patch is a hack, waiting for someone in the knowledge
of correct __attribute__ semantics.
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.
which live in msvcrt.dll and need __declspec(import) which
works by now.
Also:
- _mingw.h: conditionally define WIN32_LEAN_AND_MEAN
- malloc.h: don't undef alloca
To make this the default, enable this line in libtcc.c:tcc_new:
#if defined(TCC_TARGET_PE) && 0
s->leading_underscore = 1;
and then recompile tcc and also libtcc1.a
This fixes the i386-win32-tcc cross-compiler on x86-64 linux
platform.
I verified that it produces identical binaries for 'hello_win.exe'
and 'tcc.exe' (tcc compiled by itself) compared to the output of
the native tcc on windows.
This reverts commit 433ecdfc9d.
The patch breaks e.g. with
for ((i = 10); --i;);
In particular to check for a type decl. this is not sufficient:
if (tok < TOK_UIDENT) {
A future approach to c99 loop variables might instead use:
if (parse_btype(...)) {
plus refactor function decl() accordingly.
This enables native unwind semantics with longjmp on
win64 by putting an entry into the .pdata section for
each compiled fuction.
Also, the function now use a fixed stack and store arguments
into X(%rsp) rather than using push.
