* fix for the #include_next, v4 (final)seyko2015-10-201-19/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This version looks rigth. Comparing to the original algorithm: 1) Loop breaking. We remember a start point after wich we can try next path. Do not search include stack after this. 2) But compare next file patch with the start point. Skip if it the same. Remove "./" before comparing. PS: a problems with compaling a coreutils-8.24.51-8802e remain. There are errors messages like: src/chgrp src/chown-core.c:42: multiple definition of `make_timespec' src/chgrp.c:42: first defined here A problem is in the lib/config.h #define _GL_INLINE_ extern inline // gcc #define _GL_INLINE_ inline // tcc A long description from the lib/config.h * suppress extern inline with HP-UX cc, as it appears to be broken * suppress extern inline with Sun C in standards-conformance mode * suppress extern inline on configurations that mistakenly use 'static inline' to implement functions or macros in standard C headers like <ctype.h>. GCC and Clang are excluded from this list. Why not tcc?
* fix for the #include_next, v3seyko2015-10-191-14/+4
| | | | | | | | | | don't give an error and simply ingnore directive if we detect a loop of the #include_next. With this aproach coreutils-8.24.51-8802e compiles, but with errors: lib/libcoreutils.a: error: 'xnmalloc' defined twice lib/libcoreutils.a: error: 'xnrealloc' defined twice
* fix for the #include_next, v2seyko2015-10-171-1/+15
| | | | | | | | | A more correct fix. This one don't break old logic. But if include file is not found, we try to search again with the new compare rule. A description of the problem: http://permalink.gmane.org/gmane.comp.compilers.tinycc.devel/2769

| | | | | | | | | don't panic with error: '.' expected if there is only two '.' chars. Return tok='.' in such case. An asm code to test: jz do_move0 # .. then we have a normal low # .. or else we have a high
* tccelf.c: Reset sym after call to build_got.Edmund Grimley Evans2015-10-161-1/+3
| | | | | | | | The call to build_got can cause symtab_section->data to be reallocated (build_got -> add_elf_sym -> put_elf_sym -> section_ptr_add -> section_realloc -> tcc_realloc). This is not obvious on a cursory inspection, but fortunately Valgrind spotted it immediately. Are there other, similar bugs that Valgrind did not detect?

* Reorganize the source tree.gus knight2015-07-2745-91/+90
| | | | | | | | | | * Documentation is now in "docs". * Source code is now in "src". * Misc. fixes here and there so that everything still works. I think I got everything in this commit, but I only tested this on Linux (Make) and Windows (CMake), so I might've messed something up on other platforms...

* fix-mixed-struct (patch by Pip Cet)seyko2015-05-148-228/+452
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jsut for testing. It works for me (don't break anything) Small fixes for x86_64-gen.c in "tccpp: fix issues, add tests" are dropped in flavor of this patch. Pip Cet: Okay, here's a first patch that fixes the problem (but I've found another bug, yet unfixed, in the process), though it's not particularly pretty code (I tried hard to keep the changes to the minimum necessary). If we decide to actually get rid of VT_QLONG and VT_QFLOAT (please, can we?), there are some further simplifications in tccgen.c that might offset some of the cost of this patch. The idea is that an integer is no longer enough to describe how an argument is stored in registers. There are a number of possibilities (none, integer register, two integer registers, float register, two float registers, integer register plus float register, float register plus integer register), and instead of enumerating them I've introduced a RegArgs type that stores the offsets for each of our registers (for the other architectures, it's simply an int specifying the number of registers). If someone strongly prefers an enum, we could do that instead, but I believe this is a place where keeping things general is worth it, because this way it should be doable to add SSE or AVX support. There is one line in the patch that looks suspicious: } else { addr = (addr + align - 1) & -align; param_addr = addr; addr += size; - sse_param_index += reg_count; } break; However, this actually fixes one half of a bug we have when calling a function with eight double arguments "interrupted" by a two-double structure after the seventh double argument: f(double,double,double,double,double,double,double,struct { double x,y; },double); In this case, the last argument should be passed in %xmm7. This patch fixes the problem in gfunc_prolog, but not the corresponding problem in gfunc_call, which I'll try tackling next.

| | | | | | | | just for testing. Is it needed? I'm not a MSYS citizen. run4flat is a tcc fork by David Mertens that knows how to work with multiple symbol tables. Excelent work. A good descriptions of the tcc internals inside a code comments.
