This fixes the missed handling of external/constant mask SLP operations, for the testcase in particular masked loads. The patch adjusts the vect_check_scalar_mask API to reflect the required vect_is_simple_use SLP compatible API plus adjusts for the special handling of masked loads in SLP discovery. The issue is likely latent. 2021-06-30 Richard Biener <rguenther@suse.de> PR tree-optimization/101267 * tree-vect-stmts.c (vect_check_scalar_mask): Adjust API and use SLP compatible interface of vect_is_simple_use. Reject not vectorized SLP defs for callers that do not support that. (vect_check_store_rhs): Handle masked stores and pass down the appropriate operator index. (vectorizable_call): Adjust. (vectorizable_store): Likewise. (vectorizable_load): Likewise. Handle SLP pecularity of masked loads. (vect_is_simple_use): Remove special-casing of masked stores. * gfortran.dg/pr101267.f90: New testcase.
