[Bug tree-optimization/110937] (bool0 ? bool1^1 : bool1) is not optimized to bool0 ^ bool1
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110937 --- Comment #3 from CVS Commits --- The trunk branch has been updated by Andrew Pinski : https://gcc.gnu.org/g:7fb65f102851248bafa0815401d8bdcea6d7626c commit r14-3110-g7fb65f102851248bafa0815401d8bdcea6d7626c Author: Andrew Pinski Date: Mon Aug 7 10:47:09 2023 -0700 MATCH: [PR110937/PR100798] (a ? ~b : b) should be optimized to b ^ -(a) This adds a simple match pattern for this case. I noticed it a couple of different places. One while I was looking at code generation of a parser and also while I was looking at locations where bitwise_inverted_equal_p should be used more. Committed as approved after bootstrapped and tested on x86_64-linux-gnu with no regressions. PR tree-optimization/110937 PR tree-optimization/100798 gcc/ChangeLog: * match.pd (`a ? ~b : b`): Handle this case. gcc/testsuite/ChangeLog: * gcc.dg/tree-ssa/bool-14.c: New test. * gcc.dg/tree-ssa/bool-15.c: New test. * gcc.dg/tree-ssa/phi-opt-33.c: New test. * gcc.dg/tree-ssa/20030709-2.c: Update testcase so `a ? -1 : 0` is not used to hit the match pattern.
