tree-vect-loop.c (vect_analyze_loop_operations): Also analyze reduction PHIs.
2016-07-03 Richard Biener <rguenther@suse.de>
* tree-vect-loop.c (vect_analyze_loop_operations): Also analyze
reduction PHIs.
(vect_force_simple_reduction): Record reduction def -> phi mapping.
(vectorizable_reduction): Perform reduction PHI creation when
visiting a reduction PHI and adjust and simplify code generation
phase of the reduction op. Cache dts, use fold_binary, not fold_build2.
(vect_transform_loop): Visit reduction PHIs.
* tree-vect-slp.c (vect_get_and_check_slp_defs): Record reduction
defs into the SLP tree.
(vect_build_slp_tree): Reduction defs terminate the recursion.
* tree-vect-stmts.c (vect_get_vec_def_for_operand_1): Allow lookup
of reduction defs.
(vect_get_vec_defs_for_stmt_copy): Export.
(vect_get_vec_defs): Likewise.
* tree-vectorizer.h (struct _stmt_vec_info): Amend reduc_def
purpose.
(vect_get_vec_defs_for_stmt_copy): Declare.
(vect_get_vec_defs): Likewise.
