misc fixes including:
- tcc.c: fix "tcc -vv" for libtcc1.a on win32/PE
- tccelf.c: fix a crash when GOT has no relocs (witn -nostdlib)
- tccelf.c: fix stab linkage for zero n_strx
- tccgen.c: fix stdcall decoration for array parameters
int __stdcall func(char buf[10]) is _func@4 (was _func@12)
- tccgen.c: fix static variables with nocode/nodata_wanted
see tests2/96_nodata_wanted.c
- tccrun.c: align sections using sh_addralign (for reliable function_alignment)
- tests2/Makefile sort 100 after 99
- win32/include/sys/stat.h fix _stat and _wstat
- x86_64-gen.c: win64/gfunc_call: fix a bug with xmmN register args
previously overwrote valid other xmmN registers eventually
win32/Makefile ("for cygwin") removed
- On cygwin, the normal ./configure && make can be used with either
cygwin's "GCC for Win32 Toolchain"
./configure --cross-prefix=i686-w64-mingw32-
or with an existing tcc:
./configure --cc=<old-tccdir>/tcc.exe
tcctest.c:
- exclude test_high_clobbers() on _WIN64 (does not work)
tests2/95_bitfield.c:
- use 'signed char' for ARM (where default 'char' is unsigned)
tests:
- remove -I "expr" diff option to allow tests with
busybox-diff.
libtcc.c, tcc.c:
- removed -iwithprefix option. It is supposed to be
combined with -iprefix which we don't have either.
tccgen.c:
- fix assignments and return of 'void', as in
void f() {
void *p, *q;
*p = *q:
return *p;
}
This appears to be allowed but should do nothing.
tcc.h, libtcc.c, tccpp.c:
- Revert "Introduce VIP sysinclude paths which are always searched first"
This reverts commit 1d5e386b0a.
The patch was giving tcc's system includes priority over -I which
is not how it should be.
tccelf.c:
- add DT_TEXTREL tag only if text relocations are actually
used (which is likely not the case on x86_64)
- prepare_dynamic_rel(): avoid relocation of unresolved
(weak) symbols
tccrun.c:
- for HAVE_SELINUX, use two mappings to the same (real) file.
(it was so once except the RX mapping wasn't used at all).
tccpe.c:
- fix relocation constant used for x86_64 (by Andrei E. Warentin)
- #ifndef _WIN32 do "chmod 755 ..." to get runnable exes on cygwin.
tccasm.c:
- keep forward asm labels static, otherwise they will endup
in dynsym eventually.
configure, Makefile:
- mingw32: respect ./configure options --bindir --docdir --libdir
- allow overriding tcc when building libtcc1.a and libtcc.def with
make XTCC=<tcc program to use>
- use $(wildcard ...) for install to allow installing just
a cross compiler for example
make cross-arm
make install
- use name <target>-libtcc1.a
build-tcc.bat:
- add options: -clean, -b bindir
tccgen.c:
doubles need to be aligned, on ARM. The section_reserve()
in init_putv does not do that.
-D ONE_SOURCE: is now the default and not longer needed. Also,
tcc.h now sets the default native target. These both make
compiling tcc simple as "gcc tcc.c -o tcc -ldl" again.
arm-asm.c:
enable pseudo asm also for inline asm
tests/tests2/Makefile:
disable bitfield tests except on windows and x86_64
and don't generate-always
tcc.c:
fix a loop with -dt on errors
configure:
print compiler version (as recognized)
tccpp.c:
actually define symbols for tcc -dt
clear static variables (needed for -dt or libtcc usage)
96_nodata_wanted.c:
use __label__ instead of asm
lib/files:
use native symbols (__i386__ etc.) instead of TCC_TARGET_...
* -dt now with lowercase t
* test snippets now separated by real preprocessor statements
which is valid C also for other compilers
#if defined test_xxx
< test snippet x >
#elif defined test_yyy
< test snippet y >
#elif ...
#endif
* simpler implementation, behaves like -run if no 'test_...' macros
are seen, works with -E too
* for demonstration I combined some of the small tests for errors
and warnings (56..63,74) in "60_errors_and_warnings.c"
Also:
* libtcc.c:
put tcc_preprocess() and tcc_assemble() under the setjmp clause
to let them return to caller after errors. This is for -dt -E.
* tccgen.c:
- get rid of save/restore_parse_state(), macro_ptr is saved
by begin_macro anyway, now line_num too.
- use expr_eq for parsing _Generic's controlling_type
- set nocode_wanted with const_wanted. too, This is to keep
VT_JMP on vtop when parsing preprocessor expressions.
* tccpp.c: tcc -E: suppress trailing whitespace from lines with
comments (that -E removes) such as
NO_GOTPLT_ENTRY,\t /* never generate ... */
The existing variable 'nocode_wanted' is now used to control
output of static data too. So...
(nocode_wanted == 0)
code and data (normal within functions)
(nocode_wanted < 0)
means: no code, but data (global or static data)
(nocode_wanted > 0)
means: no code and no data (code and data suppressed)
(nocode_wanted & 0xC0000000)
means: we're in declaration of static data
Also: new option '-dT' to be used with -run
tcc -dT -run file.c
This will look in file.c for certain comment-boundaries:
/*-* test-xxx: ...some description */
and then for each test below run it from memory. This way
various features and error messages can be tested with one
single file. See 96_nodata_wanted.c for an example.
Also: tccgen.c: one more bitfield fix
