Assembler code syntax: Visual Studio vs G++

Question

0.00/5 (No votes)

See more:

I'm porting some code over to Linux (well, building it on Linux anyway) and I've hit a problem.

In VS you mark out some inline asm like this:

__asm
{
  mov eax, something
}

but for G++ it would need:

asm (
  "mov eax, something"
);

Neither compiler seems to be able to use the other syntax, is there anything I can do to avoid having duplicate copies with slightly different syntax?

Note: I'm also aware of the Intel / AT&T syntax differences, which I can already set options for.

Is it a question? This is what it is, nothing else.

AFAIK, assembly is the least portable code ever.

something as crusty as ...

// ASM abstracting header
#ifdef GPLUSPLUS

#define BEGIN_INLINE_ASM asm{
#define END_INLINE_ASM };
#define MNEM2(a,b) "a,b"

#endif

#ifdef VSTUDIO

#define BEGIN_INLINE_ASM __asm{
#define END_INLINE_ASM }
#define MNEM2(a,b) a,b

#endif

then in your 'code'

BEGIN_INLINE_ASM 
MNEM(mov eax,something)
END_INLINE_ASM

.. maybe?

Failing that, have the asm in files of another extension, and a parser that sorts them out into 'c', and build rule that runs that parser before the compiler?

Really depends how much code you're in-lining
