--- Comment #12 from irar at gcc dot gnu.org 2010-11-02 12:13:01 UTC --- Author: irar Date: Tue Nov 2 12:12:56 2010 New Revision: 166175 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=166175 Log: PR tree-optimization/45902 * tree-vectorizer.h (enum stmt_vec_info_type): Add new value for shift. (vect_get_slp_defs): Add arguments. * tree-vect-stmts.c (cost_for_stmt): Handle shifts. (vect_get_vec_def_for_operand): Use operand's type to determine number of units in the created vector. (vect_get_vec_defs): Pass scalar operands to vect_get_slp_defs. (vectorizable_shift): New function. (vectorizable_operation): Move code that handles shifts to vectorizable_shift. (vectorizable_type_demotion): Pass scalar operands to vect_get_slp_defs. (vectorizable_type_promotion, vectorizable_store): Likewise. (vect_analyze_stmt): Call vectorizable_shift. (vect_transform_stmt): Likewise. * tree-vect-slp.c (vect_get_constant_vectors): Add new argument. Use it as the operand to create vectors except for stores. (vect_get_slp_defs): Add new arguments. Pass them to vect_get_constant_vectors.
