* tccgen: nodata_wanted fix, default ONE_SOURCE, etc...grischka2017-07-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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: --config-musl/-uClibc switch & misc cleanupsgrischka2017-05-131-116/+72
| | | | | | | | | | | | | | | - configure: - add --config-uClibc,-musl switch and suggest to use it if uClibc/musl is detected - make warning options magic clang compatible - simplify (use $confvars instead of individual options) - Revert "Remove some unused-parameter lint" 7443db0d5f841b81a55e918bf8c228dd20f9ddb2 rather use -Wno-unused-parameter (or just not -Wextra) - #ifdef functions that are unused on some targets - tccgen.c: use PTR_SIZE==8 instead of (X86_64 || ARM64) - tccpe.c: fix some warnings - integrate dummy arm-asm better
* Improve musl and uclibc detectionMarc Vertes2017-05-081-1/+8
| | | | | | | Do not enable musl or uclibc native support if a GNU linker is already present. This avoids interference for example on a Debian platform with musl-dev installed. More work is required to select musl libc in that case, with additional configure flags.

* configure: fix permissionsgrischka2017-04-261-0/+0
| | | | | There must be something with git on windows that it messes up x permissions sometimes.
* final adjustments for releasegrischka2017-04-251-15/+19
| | | | | | | | | | | | | | | | | | | | | - 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
* tcc: early OSX native supportAndrei Warkentin2017-04-251-0/+8
| | | | | | | | | | | | - build scripts - working '-run' mode, e.g.: ./tcc -B. -I./include -I. -I.. -D_ANSI_SOURCE -run examples/ex1.c Note: we don't bother parsing Mach-O/Fat images yet. We blindly dlopen the image. Signed-off-by: Andrei Warkentin <andrey.warkentin@gmail.com>
* Add support of musl-libcMarc Vertes2017-04-201-0/+2
| | | | The port is functional. Bound checking is not supported yet.
* tcc: re-enable correct option -r supportgrischka2017-02-201-5/+5
| | | | | | | | | | | | | | | Forgot about it. It allows to compile several sources (and other .o's) to one single .o file; tcc -r -o all.o f1.c f2.c f3.S o4.o ... Also: - option -fold-struct-init-code removed, no effect anymore - (tcc_)set_environment() moved to tcc.c - win32/lib/(win)crt1 minor fix & add dependency - debug line output for asm (tcc -c -g xxx.S) enabled - configure/Makefiles: x86-64 -> x86_64 changes - README: cleanup

| | | | | Also remove bitfield test from tcctest.c because gcc versions don't agree among each other.

* build: win: detect also mingw64 in msys2 setupAvi Halachmi (:avih)2016-10-101-1/+1
| | | | | | | | | | MSYS2 installs 3 environments, with uname (e.g. on win8.1 64) as follows: - MINGW32_NT-6.3 gcc -> stand-alone native i686 binaries - MINGW64_NT-6.3 gcc -> stand-alone native x86_64 binaries - MSYS_NT-6.3 gcc -> posix-ish binaries which can only run in this env Therefore 'MINGW' is more generic and detects both 32/64 native environments, where previously 'MINGW32' detected only the 32 one.
* build: win32: don't use mklink - use ln or fallback to cpAvi Halachmi (:avih)2016-10-101-5/+2
| | | | | | | | | | | | | | | | | For the following reasons: - Native windows links are rarely used in general. - Require elevated privileges even if the current user has administrator privileges (needs further "run as administrator"). - Most/all windows shell environments capable of running configure already support ln (msys[1], msys2, most probably cygwin too). - If cross building tcc on linux for windows then native mklink is not available, as well as 'cmd' (in this scenario the build later fails for other reasons, but at least configures succeeds now). - cp is good enough as fallback since we only copy 5 makefiles anyway. - The only environment I'm aware of which doesn't support ln -s is busybox for windows, and with this patch it falls back to cp and completes configure successfully (and the build later succeeds, assuming valid $CC and $AR).

* win32/64: msys2 supportgrischka2016-10-021-0/+1
| | | | | | | | | | | | Support ./configure && make under msys2 (a new msys fork) on win32 and win64. Get rid of CONFIG_WIN64 make-var. (On windows, WIN32 in general is used for both 32 and 64 bit platforms) Also: - cleanup win32/build-tcc.bat - adjust win32/(doc/)tcc-win32.tx

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * fix some macro expansion issues * add some pp tests in tests/pp * improved tcc -E output for better diff'ability * remove -dD feature (quirky code, exotic feature, didn't work well) Based partially on ideas / researches from PipCet Some issues remain with VA_ARGS macros (if used in a rather tricky way). Also, to keep it simple, the pp doesn't automtically add any extra spaces to separate tokens which otherwise would form wrong tokens if re-read from tcc -E output (such as '+' '=') GCC does that, other compilers don't. * cleanups - #line 01 "file" / # 01 "file" processing - #pragma comment(lib,"foo") - tcc -E: forward some pragmas to output (pack, comment(lib)) - fix macro parameter list parsing mess from a3fc54345949535524d01319e1ca6378b7c2c201 a715d7143d9d17da17e67fec6af1c01409a71a31 (some coffee might help, next time ;) - introduce TOK_PPSTR - to have character constants as written in the file (similar to TOK_PPNUM) - allow '\' appear in macros - new functions begin/end_macro to: - fix switching macro levels during expansion - allow unget_tok to unget more than one tok - slight speedup by using bitflags in isidnum_table Also: - x86_64.c : fix decl after statements - i386-gen,c : fix a vstack leak with VLA on windows - configure/Makefile : build on windows (MSYS) was broken - tcc_warning: fflush stderr to keep output order (win32)

This is because a __bound_init inside ".init" section is not called on Windows for unknown reason. * print on stderr a message when an illegal pointer is returned: there is no segmentation violation on Windows for a program compiled with "tcc -b" * remove "C:" subdir on clean if $HOST_OS = "Linux" * default CFLAGS="-Wall -g -O0" insteed CFLAGS="-Wall -g -O2" to speed up compilation and more precise debugging.

| | | | | | | | | | | | Not able to generate ELF files on NetBSD yet (lacks the note and crt1.o is actually named crt0.o on NetBSD), but -run works with these extra defines: -D__lint__ -D"__symbolrename(x)=asm(#x)" -D__NetBSD__ The -D__lint__ is an ugly hack, TCC should be able to emulate GCC just fine, but it seems TCC doesn't support __builtin_va_list yet? typedef __builtin_va_list __va_list; /usr/include/sys/ansi.h:72: error: ';' expected (got "__va_list")
* be stricter with aliasinggrischka2014-01-071-0/+0
| | | | | | | | | | | | | | Refactoring (no logical changes): - use memcpy in tccgen.c:ieee_finite(double d) - use union to store attribute flags in Sym Makefile: "CFLAGS+=-fno-strict-aliasing" basically not necessary anymore but I left it for now because gcc sometimes behaves unexpectedly without. Also: - configure: back to mode 100755 - tcc.h: remove unused variables tdata/tbss_section - x86_64-gen.c: adjust gfunc_sret for prototype
* i386: use __fixdfdi instead of __tcc_cvt_ftolgrischka2014-01-061-1/+1
| | | | | | | | | | | | Variants __fixsfdi/__fixxfdi are not needed for now because the value is converted to double always. Also: - remove __tcc_fpinit for unix as it seems redundant by the __setfpucw call in the startup code - avoid reference to s->runtime_main in cross compilers - configure: fix --with-libgcc help - tcctok.h: cleanup
* Use libtcc.a for static link even with USE_LIBGCCThomas Preud'homme2014-01-031-1/+1
| | | | | | | When statically linking, runtime library should be static as well. tcc could link with libgcc.a but it's in a gcc version specific directory. Another solution, followed by this patch, is to use libtcc.a when statically linking, even if USE_LIBGCC was configured.
* Fix lib, include, crt and libgcc search pathsThomas Preud'homme2013-09-071-1/+1

* Improved variable length array support.James Lyon2013-04-271-0/+7
| | | | | | | | | | | | | | | VLA storage is now freed when it goes out of scope. This makes it possible to use a VLA inside a loop without consuming an unlimited amount of memory. Combining VLAs with alloca() should work as in GCC - when a VLA is freed, memory allocated by alloca() after the VLA was created is also freed. There are some exceptions to this rule when using goto: if a VLA is in scope at the goto, jumping to a label will reset the stack pointer to where it was immediately after the last VLA was created prior to the label, or to what it was before the first VLA was created if the label is outside the scope of any VLA. This means that in some cases combining alloca() and VLAs will free alloca() memory where GCC would not.
