PR tree-optimization/111115 gcc/ * tree-vectorizer.h (vect_slp_child_index_for_operand): New. * tree-vect-data-refs.cc (can_group_stmts_p): Also group .MASK_STORE. * tree-vect-slp.cc (arg3_arg2_map): New. (vect_get_operand_map): Handle IFN_MASK_STORE. (vect_slp_child_index_for_operand): New function. (vect_build_slp_tree_1): Handle statements with no LHS, masked store ifns. (vect_remove_slp_scalar_calls): Likewise. * tree-vect-stmts.cc (vect_check_store_rhs): Lookup the SLP child corresponding to the ifn value index. (vectorizable_store): Likewise for the mask index. Support masked stores. (vectorizable_load): Lookup the SLP child corresponding to the ifn mask index. gcc/testsuite/ * lib/target-supports.exp (check_effective_target_vect_masked_store): Supported with check_avx_available. * gcc.dg/vect/slp-mask-store-1.c: New testcase.
