From 7aa0d35066596b3c0fefb385bbe1ee43f75f8ec1 Mon Sep 17 00:00:00 2001 From: irar Date: Sun, 12 Jul 2009 07:09:07 +0000 Subject: * tree-parloops.c (loop_parallel_p): Call vect_is_simple_reduction with additional argument. * tree-vectorizer.h (enum vect_def_type): Add vect_double_reduction_def. (vect_is_simple_reduction): Add argument. * tree-vect-loop.c (vect_determine_vectorization_factor): Fix indentation. (vect_analyze_scalar_cycles_1): Detect double reduction. Call vect_is_simple_reduction with additional argument. (vect_analyze_loop_operations): Handle exit phi nodes in case of double reduction. (reduction_code_for_scalar_code): Handle additional codes by returning ERROR_MARK for them. Fix comment and indentation. (vect_is_simple_reduction): Fix comment, add argument to specify double reduction. Detect double reduction. (get_initial_def_for_induction): Fix indentation. (get_initial_def_for_reduction): Fix comment and indentation. Handle double reduction. Create initial definitions that do not require adjustment if ADJUSTMENT_DEF is NULL. Handle additional cases. (vect_create_epilog_for_reduction): Fix comment, add argument to handle double reduction. Use PLUS_EXPR in case of MINUS_EXPR in epilogue result extraction. Create double reduction phi node and replace relevant uses. (vectorizable_reduction): Call vect_is_simple_reduction with additional argument. Fix indentation. Update epilogue code treatment according to the changes in reduction_code_for_scalar_code. Check for double reduction. Call vect_create_epilog_for_reduction with additional argument. * tree-vect-stmts.c (process_use): Handle double reduction, update documentation. (vect_mark_stmts_to_be_vectorized): Handle double reduction. (vect_get_vec_def_for_operand): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@149526 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-parloops.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'gcc/tree-parloops.c') diff --git a/gcc/tree-parloops.c b/gcc/tree-parloops.c index 5f11fc77a1b..28c96a26f59 100644 --- a/gcc/tree-parloops.c +++ b/gcc/tree-parloops.c @@ -284,13 +284,15 @@ loop_parallel_p (struct loop *loop, htab_t reduction_list, { gimple phi = gsi_stmt (gsi); gimple reduc_stmt = NULL; + bool dummy; /* ???
