--- Comment #51 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Andrew Macleod <amacl...@gcc.gnu.org>: https://gcc.gnu.org/g:8db155ddf8cec9e31f0a4b8d80cc67db2c7a26f9 commit r12-7692-g8db155ddf8cec9e31f0a4b8d80cc67db2c7a26f9 Author: Andrew MacLeod <amacl...@redhat.com> Date: Thu Mar 17 10:52:10 2022 -0400 Always use dominators in the cache when available. This patch adjusts range_from_dom to follow the dominator tree through the cache until value is found, then apply any outgoing ranges encountered along the way. This reduces the amount of cache storage required. PR tree-optimization/102943 * gimple-range-cache.cc (ranger_cache::range_from_dom): Find range via dominators and apply intermediary outgoing edge ranges.
