builtins.c (get_pointer_alignment_1): Handle POINTER_PLUS_EXPR.
2015-07-02 Richard Biener <rguenther@suse.de>
* builtins.c (get_pointer_alignment_1): Handle POINTER_PLUS_EXPR.
* fold-const.c (get_pointer_modulus_and_residue): Remove.
(fold_binary_loc): Implement (T)ptr & CST in terms of
get_pointer_alignment_1.
* tree-vect-loop-manip.c (vect_gen_niters_for_prolog_loop):
Make sure to build the alignment test on a SSA name without
final alignment info valid only after the prologue.
