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 1d5e386b0a78393ac6b670c209a185849ec798a1.
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
add some features for more complete 'long' support tcc.h: - use LONG_SIZE=4/8 instead of TCC_LONG_ARE_64_BIT tccgen.c: - add ptrdiff_type, update size_type - support shift and ?: operations - support long enum types - display 'long' from type_to_str - nwchar_t is unsigned short on windows - unrelated: use memcpy in init_putv for long doubles to avoid random bytes in the image (if tcc was compiled by gcc) for diff purposes. tccpp.c: - make parse_number return correct types - improve multi-character-constants 'XX' 'abcd' Changelog: - update
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_...
- configure/Makefiles: minor adjustments - build-tcc.bat: add -static to gcc options (avoids libgcc_s*.dll dependency with some mingw versions) - tccpe.c/tcctools.c: eliminate MAX_PATH (not available for cross compilers) - tccasm.c: use uint64_t/strtoull in unary() (unsigned long sometimes is only uint32_t, as always on windows) - tccgen.c: Revert (f077d16c) "tccgen: gen_cast: cast FLOAT to DOUBLE" Was a rather experimental, tentative commit, not really necessary and somewhat ugly too. - cleanup recent osx support: - Makefile/libtcc.c: cleanup copy&paste code - tccpp.c: restore deleted function
since configure supports only native configuration
a file 'cross-tcc.mak' needs to be created manually.
It is included in the Makefile if present.
# ----------------------------------------------------
# Example config-cross.mak:
#
# windows -> i386-linux cross-compiler
# (it expects the linux files in <prefix>/i386-linux)
ROOT-i386 = {B}/i386-linux
CRT-i386 = $(ROOT-i386)/usr/lib
LIB-i386 = $(ROOT-i386)/lib:$(ROOT-i386)/usr/lib
INC-i386 = {B}/lib/include:$(ROOT-i386)/usr/include
DEF-i386 += -D__linux__
# ----------------------------------------------------
Also:
- use libtcc1-<target>.a instead of directories
- add dummy arm assembler
- remove include dependencies from armeabi.c/lib-arm64.c
- tccelf/ld_add_file: add SYSROOT (when defined) to absolute
filenames coming from ld-scripts
usage:
tcc -ar [rcsv] lib files...
tcc -impdef lib.dll [-v] [-o lib.def]
also:
- support more files with -c: tcc -c f1.c f2.c ...
- fix a bug which caused tcc f1.c f2.S to produce no asm
- allow tcc -ar @listfile too
- change prototype: _void_ tcc_set_options(...)
- apply -Wl,-whole-archive when a librariy is given
as libxxx.a also (not just for -lxxx)
- lib/Makefile: add (win)crt1_w.o - crt1.c/_runtmain: return to tcc & only use for UNICODE (because it might be not 100% reliable with for example wildcards (tcc *.c -run ...) - tccrun.c/tccpe.c: load -run startup_code only if called from tcc_run(). Otherwise main may not be defined. See libtcc_test.c - tests2/Makefile: pass extra options in FLAGS to allow overriding TCC Also: - tccpe.c: support weak attribute. (I first tried to solve the problem above by using it but then didn't)
'-run' suported. argvs are converted. But don't use compliled Unicode CLI exe-file to get inputs interactively in other codepage! Please add other compliling supports than 'build-tcc.bat' (Who is good at them).
- tcc-doc.texi: commandline option info update - Changelog/TODO: update - tests/tcctest.py: removed - tests/Makefile: weaktest fixed - tests/tests2: some files renamed and/or converted to unix LF - configure/Makefile: --enable-static option (no dll on win32) - win32/build-tcc.bat: msvc support - win32/tcc-win32.txt: build info update - win32/vs2015/: VS solution removed - win32/include/tcc/tcc_libm.h: #include statement fixed - tcc.c: -include <file> option help info - .gitignore: cleanup
