The following avoids blindly trusting bool pattern recog here and verifies things more thoroughly in vectorizable_phi. A bool pattern recog fix is for GCC 13. 2021-11-30 Richard Biener <rguent...@suse.de> PR tree-optimization/103489 * tree-vect-loop.c (vectorizable_phi): Verify argument vector type compatibility to mitigate bool pattern recog bug. * gcc.dg/torture/pr103489.c: New testcase.
