--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Even in the gcc 13 -fdump-tree-ccp1-details I see PHI node value: CONSTANT 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffe2 (0x19) so that isn't exactly readable either, but my changes made it much worse.
