From 9bd51351c175d345b8a9b3c19ba49ba358940272 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Tue, 2 Jul 2024 09:33:29 +0200 Subject: [PATCH] tree-optimization/115741 - ICE with VMAT_CONTIGUOUS_REVERSE and gap When we determine overrun we have to consider VMAT_CONTIGUOUS_REVERSE the same as VMAT_CONTIGUOUS. PR tree-optimization/115741 * tree-vect-stmts.cc (get_group_load_store_type): Also handle VMAT_CONTIGUOUS_REVERSE when determining overrun. --- gcc/tree-vect-stmts.cc | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gcc/tree-vect-stmts.cc b/gcc/tree-vect-stmts.cc index aab3aa59962..20b84515446 100644 --- a/gcc/tree-vect-stmts.cc +++ b/gcc/tree-vect-stmts.cc @@ -2099,7 +2099,8 @@ get_group_load_store_type (vec_info *vinfo, stmt_vec_info stmt_info, If there is a combination of the access not covering the full vector and a gap recorded then we may need to peel twice. */ if (loop_vinfo - && *memory_access_type == VMAT_CONTIGUOUS + && (*memory_access_type == VMAT_CONTIGUOUS + || *memory_access_type == VMAT_CONTIGUOUS_REVERSE) && SLP_TREE_LOAD_PERMUTATION (slp_node).exists () && !multiple_p (group_size * LOOP_VINFO_VECT_FACTOR (loop_vinfo), nunits))
