Inverse bisect says: fd8dd6c0384969170e594be34da278a072d5eb76 is the first bad commit commit fd8dd6c0384969170e594be34da278a072d5eb76 Author: Richard Biener <rguent...@suse.de> Date: Tue Nov 29 12:56:22 2022 +0100 tree-optimization/107852 - missed optimization with PHIs i.e. r13-4389-gfd8dd6c0384969. It doesn't revert cleanly on trunk so I can't test if it's sane or not.
