tree-vectorizer.h (struct _slp_oprnd_info): Remove first_const_oprnd field, rename first_def_type to first_op_type.
2013-04-10 Richard Biener <rguenther@suse.de> * tree-vectorizer.h (struct _slp_oprnd_info): Remove first_const_oprnd field, rename first_def_type to first_op_type. * tree-vect-slp.c (vect_create_oprnd_info): Adjust. (vect_get_and_check_slp_defs): Always use the type of the operand. Allow mixed vect_external_def, vect_constant_def types. (vect_get_constant_vectors): Handle mixed vect_external_def, vect_constant_def types. * gcc.dg/vect/slp-39.c: New testcase. From-SVN: r197669
