--- Comment #8 from irar at gcc dot gnu.org 2012-02-05 05:58:22 UTC --- Author: irar Date: Sun Feb 5 05:58:18 2012 New Revision: 183902 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=183902 Log: PR tree-optimization/52091 * tree-vectorizer.h (vect_is_simple_use): Add an argument. (vect_is_simple_use_1): Likewise. * tree-vect-loop.c (vectorizable_reduction): Update calls to vect_is_simple_use_1 and vect_is_simple_use. (vectorizable_live_operation): Likewise. * tree-vect-patterns.c (widened_name_p, vect_recog_vector_vector_shift_pattern, check_bool_pattern): Likewise. * tree-vect-stmts.c (process_use, vect_get_vec_def_for_operand, vectorizable_call, vectorizable_conversion, vectorizable_assignment, vectorizable_shift, vectorizable_operation, vectorizable_store, vectorizable_load): Likewise. (vect_is_simple_cond): Add an argument, pass it to vect_is_simple_use_1. (vectorizable_condition): Update calls to vect_is_simple_cond, vect_is_simple_use. (vect_is_simple_use): Add an argument, the statement in which OPERAND is used. Check that if OPERAND's def stmt is a double reduction phi node, the use is a phi node too. (vect_is_simple_use_1): Add an argument, pass it to vect_is_simple_use. * tree-vect-slp.c (vect_get_and_check_slp_defs): Update a call to vect_is_simple_use.
