Like so:
#include <stdio.h>
#define __str_1(x) #x
#define __str(x) __str_1(x)
/* x86-64 */
#define bne_ptr(_a, _b, _label) \
asm goto ( \
"cmpq %[a], %[b]\n\t" \
"jne %l[" __str(_label) "]\n\t" \
: : [a] "r" (_a), [b] "r" (_b) \
: : _label)
int x;
int v[2];
int main(void)
{
bne_ptr(v, v + 1, label_same);
x = 1;
label_same:
Note that this label should probably be called "label_ne".
I flipped the macro logic without changing the labels.
Thanks,
Mathieu
printf("%d\n", x);
return 0;
