2011-10-24 Richard Guenther <rguenther@suse.de>
* tree-vect-stmts.c (vect_get_vec_def_for_operand): Convert constants
to vector element type.
(vectorizable_assignment): Bail out for non-mode-precision operations.
(vectorizable_shift): Likewise.
(vectorizable_operation): Likewise.
(vectorizable_type_demotion): Likewise.
(vectorizable_type_promotion): Likewise.
(vectorizable_store): Handle non-mode-precision stores.
(vectorizable_load): Handle non-mode-precision loads.
(get_vectype_for_scalar_type_and_size): Return a vector type
for non-mode-precision integers.
* tree-vect-loop.c (vectorizable_reduction): Bail out for
non-mode-precision reductions.
* gcc.dg/vect/vect-bool-1.c: New testcase.
