Re: [Tinycc-devel] x86-64 port

Hi,

I pushed all of my patch into mob branch.

Most patches are trivial. Replacing Elf32 to ElfW or int to long or using 
sizeof(ElfW(Dyn)) instead of 8 or something. The main change, which introduces 
x86-64 support, is the following change. This change is mostly done inside 
TCC_TARGET_X86_64. So, I think it doesn't make sense to split this change into 
smaller pieces.

Another change I should mention is the following change. This change introduces 
__builtin_frame_address(0), which is one of GCC extension. I think introducing 
this extension is the simplest way to implement stdarg.h (in GCC x86-64 ABI, 
integers and floating point values are passed by registers, and the address of 
the last argument isn't sufficient). I think this extension is useful (e.g., 
obtain stack trace) and the change is relatively small. So, I didn't enclose 
this change with #ifdef TCC_TARGET_X86_64.

Please tell me if there are something wrong, and I'll fix them.

Thanks,
