--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> ---
The trunk branch has been updated by Andrew Pinski <pinskia@gcc.gnu.org>:
https://gcc.gnu.org/g:64d90d06d2db43538c8a45adbb3d74842f7868ae
commit r14-1597-g64d90d06d2db43538c8a45adbb3d74842f7868ae
Author: Andrew Pinski <apinski@marvell.com>
Date: Wed May 24 07:08:45 2023 +0000
Add match patterns for `a ? onezero : onezero` where one of the two
operands are constant
This adds a match pattern that are for boolean values
that optimizes `a ? onezero : 0` to `a & onezero` and
`a ? 1 : onezero` to `a | onezero`.
This was reported a few times and I thought I would finally
add the match pattern for this.
This hits a few times in GCC itself too.
Notes on the testcases:
* phi-opt-2.c: This now is optimized to `a & b` in phiopt rather than
ifcombine
* phi-opt-25b.c: The test part that was failing was parity which now gets
`x & y` treatment.
* ssa-thread-21.c: there is no longer a threading opportunity, so need to
disable phiopt.
Note PR 109957 is filed for the now missing optimization in that testcase
too.
