--- Comment #25 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
We have this now:
if (tmp.3_3 > 0)
goto <bb 3>; [59.00%]
else
goto <bb 4>; [41.00%]
<bb 3> [local count: 633507679]:
_10 = _12 == 0;
<bb 4> [local count: 1073741824]:
# iftmp.2_5 = PHI <_10(3), 0(2)>
I suspect what we could do is in isel change that to:
iftmp.2_5 = tmp.3_3 > 0 ? _12 == 0 : 0;
(which itself gets optimized to:
iftmp.2_5 = (tmp.3_3 > 0) & (_12 == 0)
Which should produce better code at least.
