Bug ID: 71947
Summary: x ^ y not folded to 0 if x == y
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: prathamesh3492 at gcc dot gnu.org
Target Milestone: ---
Hi,
For the following case:
int f(int x, int y)
{
int ret;
if (x == y)
ret = x ^ y;
else
ret = 1;
return ret;
}
x ^ y does not get folded to 0.
From the discussion in:
https://gcc.gnu.org/ml/gcc-patches/2016-07/msg00385.html
r233207 must have regressed this test-case.
Thanks,
Prathamesh
