Shinichiro Hamaji 0ed7ba3f5e Support struct arguments with stdarg.h 
- add __builtin_va_arg_types to check how arguments were passed
- move most code of stdarg into libtcc1.c
- remove __builtin_malloc and __builtin_free
- add a test case based on the bug report

Shinichiro Hamaji 07fd82b411 Make alignments for struct arguments 8 bytes 
The ABI (http://www.x86-64.org/documentation/abi.pdf) says
"The size of each argument gets rounded up to eightbytes"

Shinichiro Hamaji 45e1ae2896 One more fix for tcc -run 
We don't need r_addend for addresses in PLT.

Shinichiro Hamaji d457addfc3 Fix for the previous commit. 
R_X86_64_PLT32 for .so doesn't need DLL relocation.

Shinichiro Hamaji 0ae39f1957 Handle r_addend and R_X86_64_PLT32 properly. 
- r_addend should be applied for PLT entries as well
- R_X86_64_PLT32 should be handled just like R_X86_64_PC32
- spec says GLOB_DAT and JUMP_SLOT don't need r_addend (not tested)

Now we can -run ELF objects generated by GCC.

Shinichiro Hamaji f2d7998a96 Copy tcclib.h to tests directory so GCC uses its own headers. 
http://repo.or.cz/w/tinycc.git/commit/86ffc4812952f11a35afa19b24a3e6d1a12f4490

removed this cp command. However, it was necessary to pass tests on x86-64
because include/stdarg.h is different from GCC's definition on x86-64.

Shinichiro Hamaji c31dc7aa0c Fix casts from 32bit integer types to 64bit integer types. 
This bug was reported in
http://lists.gnu.org/archive/html/tinycc-devel/2010-08/msg00050.html

In this case, we should not emit any code when we cast from VT_FUNC to VT_PTR.

Shinichiro Hamaji 9d347f8742 Probably wrong stack alignment for struct on Win64 2010-08-27 02:49:09 +09:00
Shinichiro Hamaji 1f6781f0ee Fix alignment around struct for SSE. 
- Fix a wrong calculation for size of struct
- Handle cases where struct size isn't multple of 8
- Recover vstack after memcpy for pushing struct
- Add a float parameter for struct_assign_test1 to check SSE alignment
