--- Comment #12 from Daniel Fruzynski <bugzi...@poradnik-webmastera.com> ---
One more test case. Code compiled with TEST defined is branchless, without it
has branch.
[code]
#include <stdint.h>
#define TEST
void test(uint64_t* a)
{
uint64_t n = *a / 8;
if (0 == n)
n = 1;
#ifdef TEST
*a += n;
#else
*a += 1 << n;
#endif
}
[/code]
