From 1272573a6b2257a7ed525a81e26862a563fb68a0 Mon Sep 17 00:00:00 2001 From: Richard Biener Date: Wed, 4 Nov 2020 11:37:52 +0100 Subject: add costing to SLP vectorized PHIs I forgot to cost vectorized PHIs. Scalar PHIs are just costed as scalar_stmt so the following costs vector PHIs as vector_stmt. 2020-11-04 Richard Biener * tree-vectorizer.h (vectorizable_phi): Adjust prototype. * tree-vect-stmts.c (vect_transform_stmt): Adjust. (vect_analyze_stmt): Pass cost_vec to vectorizable_phi. * tree-vect-loop.c (vectorizable_phi): Do costing. --- gcc/tree-vect-loop.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'gcc/tree-vect-loop.c') diff --git a/gcc/tree-vect-loop.c b/gcc/tree-vect-loop.c index 6cb2286..5e7188a 100644 --- a/gcc/tree-vect-loop.c +++ b/gcc/tree-vect-loop.c @@ -7548,7 +7548,7 @@ vectorizable_lc_phi (loop_vec_info loop_vinfo, bool vectorizable_phi (vec_info *, stmt_vec_info stmt_info, gimple **vec_stmt, - slp_tree slp_node) + slp_tree slp_node, stmt_vector_for_cost *cost_vec) { if (!is_a (stmt_info->stmt) || !slp_node) return false; @@ -7577,6 +7577,8 @@ vectorizable_phi (vec_info *, "incompatible vector types for invariants\n"); return false; } + record_stmt_cost (cost_vec, SLP_TREE_NUMBER_OF_VEC_STMTS (slp_node), + vector_stmt, stmt_info, vectype, 0, vect_body); STMT_VINFO_TYPE (stmt_info) = phi_info_type; return true; } -- cgit v1.1
