Guess you want it in x86 (not the fastest method, just to show you an
example):
asm volatile
(
"cld
movl $10,%%ecx
rep
stosb"
:
: "S"(source), "D"(dest)
: "esi", "edi", "ecx"
);
BTW I had to change the declaration of the arrays from:
int source[10], dest[10];
to:
int *source = new int[10], *dest = new int[10];
to avoid an "inconsistent operand constraints in an `asm'" error at
compile time... if someone knows why, i'm interested.
You can find pointers on AT&T syntax and DJGPP inline assembly in the
DJGPP FAQ, section 18.13
