* Favor arm hardfloat over arm softfloat.Thomas Preud'homme2013-01-291-4/+4
| | | | | | | Favor ARM hardfloat over ARM softfloat calling convention. In particular, this solve the problem of the raspbian distribution where the softfloat ld.so pathname (lib/ld-linux.so.3) is actually a symlink to the hardfloat ld.so pathname (/lib/arm-linux-gnueabihf/ld-2.13.so).
* Fix overflow detection in ARM relocationThomas Preud'homme2013-01-281-2/+2
| | | | | | Fix overflow detection for R_ARM_CALL, R_ARM_PC24, R_ARM_JUMP24 and R_ARM_PLT32 relocations on ARM. 26 bits means 25 bits for positive and negative offsets !
* Fix stack alignment on 8 bytes at function callThomas Preud'homme2013-01-271-3/+3
| | | | | Ensure stack pointer is correctly adjusted in prolog to be aligned on 8 bytes after the change of frame linking.
* Don't do builtin_frame_address test with ARM gccThomas Preud'homme2013-01-261-0/+2
| | | | | | | | gcc fails the builtin_frame_address test on ARM so we disable it. As a consequence, the diff between gcc and tcc's output is unecessarily bigger. Given the big size of the diff currently, this doesn't make a big difference but may allow to detect a regression in tcc's implementation of builtin_frame_address.
* Organize frames in a real linked list on ARMThomas Preud'homme2013-01-261-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the linking of the frames on ARM. Instead of having fp points 12 bytes above where the old fp is stored, let fp points where the old fp is stored. That is, we switch from: | . | | . | | . | | | | params | <-- fp -------- | oldlr | -------- | oldip | -------- | oldfp | -------- to: | . | | . | | . | | | | params | -------- | oldlr | -------- | oldip | -------- | oldfp | <-- fp --------
* Use gcc to generate tcctest.gccThomas Preud'homme2013-01-251-1/+1

* Link STT_GNU_IFUNC into STT_FUNC in executable.Thomas Preud'homme2013-01-251-2/+11
| | | | | | | | Indirect functions shall have STT_FUNC type in executable dynsym section. Indeed, a dlsym call following a lazy resolution would pick the symbol value from the executable dynsym entry. This would contain the address of the function wanted by the caller of dlsym instead of the address of the function that would return that address.
* win32: _mingw.h: do not undef NULLgrischka2013-01-242-2/+1
| | | | | | | | | Not wise if stddef.h was already included. This is related to commit 3aa26a794e24a298493a2bc9d70fbd9aebf6437a Instead hack stddef.h to have identical definition and thus avoid the issue mentionned there.
* Fix [f]getc return value usage in 40_stdio testThomas Preud'homme2013-01-241-1/+1
| | | | | | Store [f]getc return value into an int instead of char, as per prototype. This fix an issue when char is unsigned (as is on arm for both tcc and gcc).
* Revert "Optimize vswap()"grischka2013-01-142-33/+8
| | | | | | | | | | This reverts commit 63193d1794b037eb4f3b6551596fa8a6d423e0c3. Had some problems (_STATIC_ASSERT) and was too ugly anyway. For retry, I'd suggest to implement a general function static inline void memswap (void *p1, void* p2, size_t n); and then use that. If you do so, please keep the original code as comment.
* Revert mistake in "win32: malloc.h: fix win32 ... _STATIC_ASSERT"grischka2013-01-142-69/+0
| | | | | | | from commit fc574f14984d11f1ead50560d1bdc5ae0eaf6d8d. The files from include are copied to win32/include with make install or build-tcc.bat.
* Fix out-of-tree build with relative path to rootThomas Preud'homme2013-01-141-2/+2
| | | | | Fix path of Makefile symlinks in a out-of-tree build where the root directory of the source is given as a relative path.
* Install libtcc.h when invoking make installThomas Preud'homme2013-01-141-0/+2
| | | | This fix commit e79281f58ec302e8cc9dfc7d00e06f426fcd2acd

| | | | | | | | monolitic executable or library that contains all needed to compile programs, truly tinycc portable." This reverts commit 59e18aee0e509a3ca75dbe6f909e18c1d17893d1. tcc is being stabilized now in order to do a new release soon. Therefore, such a change is not appropriate now.
* Revert "pe: fix tcc not linking to user32 and gdi32"Thomas Preud'homme2013-01-141-1/+1
| | | | | | This reverts commit 943574aba54713ca4a17fe33aadde5abee233b53. The empty string in "libs" was intended behavior, as can be seen from the "if (0 == *p)" below.
* Stop setting -Wno-unused-result switch in MakefileThomas Preud'homme2013-01-131-11/+0
| | | | | | | | | | This commit revert commit 061b5799cc1feb15014da589ea98057deda14a23 and subsequent commits to detect whether -Wno-unused-result is supported or not by the compiler used to compile tcc. No warning about unused results is issued in a normal build and thus this switch is only needed if calling make with extra switches in CFLAGS or CPPFLAGS. It should thus be added with the extra switches when calling make and not in the Makefile.
* Fix C99ism in vswap()Thomas Preud'homme2013-01-131-1/+2
| | | | | Declare vtopl in vswap at the beginning of the function before any assignments. Doing otherwise means C99 is assumed when compiling.
* Added what I call virtual io to tinycc this way we can make a monolitic ↵mingodad2013-01-1112-62/+903
| | | | | | executable or library that contains all needed to compile programs, truly tinycc portable. Tested under linux exec the "mk-it" shell script and you'll end up with a portable tinycc executable that doesn't depend on anything else.
* Fix "Optimize cstr_reset() to only reset string to empty"grischka2013-01-061-1/+1
| | | | | | This fixes commit 8eb92e605200b1fe8d570ad309e28245c3f1af0a Remove memory leak.
* tccpp: alternative fix for #include_next infinite loop buggrischka2013-01-064-78/+39
| | | | | | | | | | | | | | | This replaces commit 3d409b08893873b917ccb8c34398bc41a4e84d7c - revert old fix in libtcc.c - #include_next: look up the file in the include stack to see if it is already included. Also: - streamline include code - remove 'type' from struct CachedInclude (obsolete because we check full filename anyway) - remove inc_type & inc_filename from struct Bufferedfile (obsolete) - fix bug with TOK_FLAG_ENDIF not being reset - unrelated: get rid of an 'variable potentially uninitialized' warning
* Stop returning 0 in cmp_comparison_testThomas Preud'homme2013-01-061-1/+0
| | | | cmp_comparison_test has no return value and should thus not return 0.
* Honor CC when testing for -Wno-unused-resultThomas Preud'homme2013-01-061-1/+1
| | | | | | The compiler used for compiling tcc is the one referenced in the CC variable. As such, the check for -Wno-unused-result presence should be done on CC.
