Even more funny with the variant using ctr % 64:
test ()
{
unsigned int ivtmp.28;
int pretmp.27;
int pretmp.26;
uint8_t pretmp.25;
uint8_t ctr;
int D.1293;
int D.1292;
<bb 0>:
ctr = 0;
<L0>:;
__asm__ __volatile__("nop"::);
xx = ctr;
ctr = ctr + 1;
if (ctr != 64) goto <L0>; else goto <L1>;
<L1>:;
return;
}
Lots of variables ivtmp.*, but the counter handling and modulo is done
on the ctr, compared to the less-than, where counter handling and
comparison is done on one of the ivtmp.* variables.
