* tccgen: nodata_wanted fix, default ONE_SOURCE, etc...grischka2017-07-231-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | 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_...
* tcc -dt -run ... : simpler is bettergrischka2017-07-201-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * -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 ... */
* Fix cross compilersMichael Matz2017-07-161-0/+2
| | | | Only native compilers support -run and hence the new -dT.
* tccgen: nodata_wantedgrischka2017-07-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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

* tccgen/win32: let __declspec(dllimport) imply externgrischka2017-04-041-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Also, retain storage qualifiers in type_decl, in particular also for function pointers. This allows to get rid of this very early hack in decl() type.t |= (btype.t & VT_STATIC); /* Retain "static". */ which was to fix the case of int main() { static int (*foo)(); ... Also: - missing __declspec(dllimport) is an error now - except if the symbol is "_imp__symbol" - demonstrate export/import of data in the dll example (while 'extern' isn't strictly required with dllimport anymore) - new function 'patch_storage()' replaces 'weaken_symbol()' and 'apply_visibility()' - new function 'update_storage()' applies storage attributes to Elf symbols. - put_extern_sym/2 accepts new pseudo section SECTION_COMMON - add -Wl,-export-all-symbols as alias for -rdynamic - add -Wl,-subsystem=windows for mingw compatibility - redefinition of 'sym' error for initialized global data

* cross-compilers: allow individual configurationgrischka2017-02-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* tcc: re-enable correct option -r supportgrischka2017-02-201-25/+27
| | | | | | | | | | | | | | | 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

* tcc: don't use pstrcpy, fix win32 spanwn quotinggrischka2017-02-081-18/+50
| | | | | | | | | | | | - we're now exporting tcc_prefixed symbols from libtcc only - On windows, the msvcrt startup code would remove backslashes from commandline arguments such as -DFOO=\"foo\" which would appear in argv as -DFOO="foo" Therefor before passing these to spawnvp, we need to restore the backslashes.

| | | | | | | | | | | handle mms-bitfields as sub-options of -m. (-mfloat-abi is still special because it requires arguments) tcc.c: help(): - list -mms-bitfields under 'Target specific options' libtcc.c/MEM_DEBUG - add check for past buffer writes
* Change dependency file format a bitMichael Matz2016-12-151-1/+1
| | | | | | | The linux fixdep parse is very stupid and only recognizes a target token when ':' is part of it. A space is permitted in Makefile syntax, but it's easier to change our emitter than all fixdep parsers out there.

* Revert "--whole-archive support"grischka2016-10-011-16/+2
| | | | | | | | | | | | - would parse linker args in two different places - would mess up "tcc -v ..." output: tcc -v test.c -> test.c +> test.c - would use function "tcc_load_alacarte()" to do the contrary of what its name suggests. This reverts commit 19a169ceb896f78205bc23b847938c58f14d1dda.
* --whole-archive supportseyko2016-05-201-2/+16
| | | | | | | | | | | | | | | A patch is implemented as suggested in tinycc-devel mail list. From: Reuben Thomas Date: Thu, 31 Jul 2014 16:52:53 +0100 Subject: [PATCH] Add --{no,}-whole-archive support I resurrected the patch supplied to the mailing list in 2009 Since --whole-archive is a useful flag to get tcc working with autotools, and of course in its own right, I suggest you have a look at the patch and see if it is acceptable. I cannot see any suggestion that it was actively rejected last time round, just no evidence that it was ever added.

* Improve hash performanceVlad Vissoultchev2016-04-171-3/+4
| | | | | | | | | | | | - better `TOK_HASH_FUNC` - increases `hash_ident` initial size to 16k (from 8k) - `cstr_cat` uses single `realloc` + `memcpy` - `cstr_cat` can append terminating zero - `tok_str_realloc` initial size to 16 (from 8) - `parse_define` uses static `tokstr_buf` - `next` uses static `tokstr_buf` - fixes two latent bugs (wrong deallocations in libtcc.c:482 and tccpp.c:2987)

* Allow tcc arguments to be read from @listfilesseyko2016-04-131-0/+1
| | | | | | | | | | | | | | | | | From: Vlad Vissoultchev Date: Tue, 12 Apr 2016 20:43:15 +0300 Subject: Allow tcc arguments to be read from @listfiles This allows all @ prefixed arguments to be treated as listfiles containing list of source files or tcc options where each one is on a separate line. Can be used to benchmark compilation speed with non-trivial amount of source files. The impl of `tcc_parse_args` had to be moved to a new function that is able to be called recursively w/ the original one remaining as a driver of the new one. Listfiles parsing happens in a new `args_parser_add_listfile` function that uses `tcc_open`/`tcc_close/inp` for buffered file input.

| | | | | | | | | | | | | | From: Vlad Vissoultchev Date: Mon, 11 Apr 2016 01:26:32 +0300 Subject: Fix pragma once guard when compiling multiple source files When compiling multiple source files directly to executable cached include files guard was incorrectly checked for TOK_once in ifndef_macro member. If two source files included the same header guarded by pragma once, then the second one erroneously skipped it as `cached_includes` is not cleared on second `tcc_compile`

* Skip math library if not found when -lm option is usedVlad Vissoultchev2016-04-081-2/+5
| | | | | | This only silences "cannot find library" error and allows Makefiles targeting gcc to not complain about missing libraries If there is custom libm then standard handling applies.
* Implement -dM preprocessor option as in gccVlad Vissoultchev2016-04-061-0/+3
| | | | | | There was already support for -dD option but in contrast -dM dumps only `#define` directives w/o actual preprocessor output. The original -dD output differs from gcc output by additional comment in front of `#define`s so this quirk is left for -dM as well.
