The patch exclude a case from zero check skip in
CTLZ idiom recognition (r303102).
Summary:
The following case:
i = 1;
if(n)
while (n >>= 1)
i++;
use(i);
Was converted to:
i = 1;
if(n)
i += builtin_ctlz(n >> 1, false);
use(i);
Which is not correct. The patch make it:
i = 1;
if(n)
i += builtin_ctlz(n >> 1, true);
use(i);
