--- Comment #27 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:d4d12a548f210371609e85f6d2f4f3ee0e2b04f2 commit r12-11079-gd4d12a548f210371609e85f6d2f4f3ee0e2b04f2 Author: Martin Jambor <mjam...@suse.cz> Date: Mon Apr 7 13:32:10 2025 +0200 sra: Clear grp_same_access_path of acesses created by total scalarization (PR118924) During analysis of PR 118924 it was discussed that total scalarization invents access paths (strings of COMPONENT_REFs and possibly even ARRAY_REFs) which did not exist in the program before which can have unintended effects on subsequent AA queries. Although not doing that does not mean that SRA cannot create such situations (see the bug for more info), it has been agreed that not doing this is generally better. This patch therfore makes SRA fall back on creating simple MEM_REFs when accessing components of an aggregate corresponding to what a SRA variable now represents. gcc/ChangeLog: 2025-03-26 Martin Jambor <mjam...@suse.cz> PR tree-optimization/118924 * tree-sra.cc (create_total_scalarization_access): Set grp_same_access_path flag to zero. (cherry picked from commit 40445711b8af113ef423d8bcac1a7ce1c47f62d7)
