Hi all; quick question: Is there a list of x86 register
names for the asm() extension? I've figured out from
reading other posts that:
a eax
b ebx
c ecx
d edx
S esi
D edi
but what about the rest? Also, is there a syntax for the
16-bit and 8-bit registers? E.g. could I do something like
asm( "blahblah" : "=al" (x), "=ah" (y) ) ;
Apologies if there's a better group to ask this in; I couldn't
think of any.
