[Bug tree-optimization/101039] Some simple fold_cond_expr_with_comparison with CMP 0 is not simplified if expanded
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101039 --- Comment #3 from CVS Commits --- The master branch has been updated by Andrew Pinski : https://gcc.gnu.org/g:7d6979197274a662da7bdc564314afe8415865c1 commit r12-2041-g7d6979197274a662da7bdc564314afe8415865c1 Author: Andrew Pinski Date: Sat Jun 12 19:45:20 2021 -0700 Port most of the A CMP 0 ? A : -A to match To improve phiopt and be able to remove abs_replacement, this ports most of "A CMP 0 ? A : -A" from fold_cond_expr_with_comparison to match.pd. There is a few extra changes that are needed to remove the "A CMP 0 ? A : -A" part from fold_cond_expr_with_comparison: * Need to handle (A - B) case * Need to handle UN* comparisons. I will handle those in a different patch. Note phi-opt-15.c test needed to be updated as we get ABSU now instead of not getting ABS. When ABSU was added phiopt was not updated even to use ABSU instead of not creating ABS. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/ChangeLog: PR tree-optimization/101039 * match.pd (A CMP 0 ? A : -A): New patterns. * tree-ssa-phiopt.c (abs_replacement): Delete function. (tree_ssa_phiopt_worker): Don't call abs_replacement. Update comment about abs_replacement. gcc/testsuite/ChangeLog: PR tree-optimization/101039 * gcc.dg/tree-ssa/phi-opt-15.c: Update test to expect ABSU and still not expect ABS_EXPR. * gcc.dg/tree-ssa/phi-opt-23.c: New test. * gcc.dg/tree-ssa/phi-opt-24.c: New test.

Patch submitted here: https://gcc.gnu.org/pipermail/gcc-patches/2021-June/573785.html I guess I should add a few testcases to the patch.
