[Mingw-users] asm in MSC and in GCC

[Soren A. <so...@wo...>]

Hello,

Please, I think somebody on this List knows how this might work ..

I have a Perl module written by a fellow who has only built it using M$ 
tools. It uses _asm{  stuff .. }  and the gcc preprocessor chokes on it. I have 
taken a look at the manual for gcc and I don't think gcc supports this, but 
does support certain uses of `asm'. First of all, I don't know what the M$C 
syntax is doing, precisely. If I understood why they get away with using the 
curly braces but gcc users cannot, and what an equivalent way of doing such 
code in gcc might by, I think I could fix up this module (Win32::API) with 
protective #defines and make a contribution. The first instance in the xs file 
(that generated the C file when make is run) of this problem is pasted here:

---- code -- watch for wrapping ---

void AbstractCallback() {

	LPBYTE self;
	_asm {
		pop		eax
		mov     dword ptr self, eax
	}
	printf("AbstractCallback: got eax=%ld\n", self);
}

---- end code ----------------------

Looking forward to help on this.
