From 81f3d963e05de8b17d4ccc7667ead9ed156193a4 Mon Sep 17 00:00:00 2001 From: Tejas Belagod Date: Wed, 6 Mar 2024 15:30:26 +0530 Subject: vect: Call vect_convert_output with the right vecitype [PR114108] This patch fixes a bug where vect_recog_abd_pattern called vect_convert_output with the incorrect vecitype for the corresponding pattern_stmt. vect_convert_output expects vecitype to be the vector form of the scalar type of the LHS of pattern_stmt, but we were passing in the vector form of the LHS of the new impending conversion statement. This caused a skew in ABD's pattern_stmt having the vectype of the following gimple pattern_stmt. 2024-03-06 Tejas Belagod gcc/ChangeLog: PR middle-end/114108 * tree-vect-patterns.cc (vect_recog_abd_pattern): Call vect_convert_output with the correct vecitype. gcc/testsuite/ChangeLog: * gcc.dg/vect/pr114108.c: New test. --- gcc/tree-vect-patterns.cc | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'gcc/tree-vect-patterns.cc') diff --git a/gcc/tree-vect-patterns.cc b/gcc/tree-vect-patterns.cc index d562f57..4f491c6 100644 --- a/gcc/tree-vect-patterns.cc +++ b/gcc/tree-vect-patterns.cc @@ -1576,9 +1576,8 @@ vect_recog_abd_pattern (vec_info *vinfo, && !TYPE_UNSIGNED (abd_out_type)) { tree unsign = unsigned_type_for (abd_out_type); - tree unsign_vectype = get_vectype_for_scalar_type (vinfo, unsign); - stmt = vect_convert_output (vinfo, stmt_vinfo, unsign, stmt, - unsign_vectype); + stmt = vect_convert_output (vinfo, stmt_vinfo, unsign, stmt, vectype_out); + vectype_out = get_vectype_for_scalar_type (vinfo, unsign); } return vect_convert_output (vinfo, stmt_vinfo, out_type, stmt, vectype_out); -- cgit v1.1
