--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jeff Law <[email protected]>: https://gcc.gnu.org/g:8cd878a2f0a56059cac99c260771c283091d0601 commit r16-6527-g8cd878a2f0a56059cac99c260771c283091d0601 Author: Jeff Law <[email protected]> Date: Tue Jan 6 16:16:56 2026 -0700 [PR target/123269] Adjust predcomm testcases to avoid vectorization Thankfully this "bug" is just a case where after Robin's change we're vectorizing cases we weren't before which in turn doesn't give predcom the opportunity to optimize the code. Like on existing predcom test we can restore the test's intent by using -fno-tree-vectorize. Tested x86_64 and the various crosses to ensure nothing regressed. Pushing to the trunk. PR target/123269 gcc/testsuite * gcc.dg/tree-ssa/predcom-dse-4.c: Disable vectorization. * gcc.dg/tree-ssa/predcom-dse-7.c: Likewise.
