targhooks.c (default_builtin_vectorized_conversion): Handle vec_construct, using vectype to base cost on subparts.
2012-06-13 Bill Schmidt <wschmidt@linux.ibm.com>
* targhooks.c (default_builtin_vectorized_conversion): Handle
vec_construct, using vectype to base cost on subparts.
* target.h (enum vect_cost_for_stmt): Add vec_construct.
* tree-vect-stmts.c (vect_model_load_cost): Use vec_construct
instead of scalar_to-vec.
* config/spu/spu.c (spu_builtin_vectorization_cost): Handle
vec_construct in same way as default for now.
* config/i386/i386.c (ix86_builtin_vectorization_cost): Likewise.
* config/rs6000/rs6000.c (rs6000_builtin_vectorization_cost):
Handle vec_construct, including special case for 32-bit loads.
