--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:82a9c3b4850be48ed1ed5cc471720a2445d50443 commit r17-5736-g82a9c3b4850be48ed1ed5cc471720a2445d50443 Author: Richard Biener <[email protected]> Date: Thu Oct 29 10:02:35 2026 +0100 tree-optimization/128277 - simple latches for CCP With CCP we really want less latch edges because those eventually trigger re-simulation of the header PHI separately, so initialize loops with LOOPS_HAVE_SIMPLE_LATCHES. This causes gcc.dg/tree-ssa/loop-25.c to regress because we now disambiguate earlier. PR tree-optimization/128277 * tree-ssa-ccp.cc (do_ssa_ccp): Initialize loops with LOOPS_HAVE_SIMPLE_LATCHES. * gcc.dg/tree-ssa/loop-25.c: Adjust.
