--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:25add4b65a3bac262685d290a4dc93884a022576 commit r13-8719-g25add4b65a3bac262685d290a4dc93884a022576 Author: Richard Biener <rguent...@suse.de> Date: Wed Dec 13 08:45:58 2023 +0100 tree-optimization/112991 - re-do PR112961 fix The following does away with the fake edge adding as in the original PR112961 fix and instead exposes handling of entry PHIs as additional parameter of the region VN run. PR tree-optimization/112991 PR tree-optimization/112961 * tree-ssa-sccvn.h (do_rpo_vn): Add skip_entry_phis argument. * tree-ssa-sccvn.cc (do_rpo_vn): Likewise. (do_rpo_vn_1): Likewise, merge with auto-processing. (run_rpo_vn): Adjust. (pass_fre::execute): Likewise. * tree-if-conv.cc (tree_if_conversion): Revert last change. Value-number latch block but disable value-numbering of entry PHIs. * tree-ssa-uninit.cc (execute_early_warn_uninitialized): Adjust. * gcc.dg/torture/pr112991.c: New testcase. * g++.dg/vect/pr112961.cc: Likewise.
