--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
After my patch for PR 92342, we get:
_4 = a_9(D) == b_10(D) ? c_11(D) : 0;
_8 = a_9(D) != b_10(D) ? d_12(D) : 0;
_13 = _4 | _8;
A few patterns are needed here really:
One pattern simple is:
(simplify
(bit_ior:c
(cond @0 @1 integer_zero_p)
(cond @0 integer_zero_p @2))
(cond @0 @1 @2))
But the next one is harder and requires a double for loop. I will handle it
soon.
