commit r15-2302-gcfd3f06b4c65e15d4f6af8bd4862b835efd61a72 Author: Richard Biener <rguent...@suse.de> Date: Thu Jul 25 08:34:20 2024 +0200 tree-optimization/116081 - typedef vs. non-typedef in vectorization The following addresses a behavioral difference in vector type analysis for typedef vs. non-typedef. It doesn't fix the issue at hand but avoids a spurious difference in the dumps. PR tree-optimization/116081 * tree-vect-stmts.cc (vect_get_vector_types_for_stmt): Properly compare types.
