2008-09-11 Richard Guenther <rguenther@suse.de>
* tree-vectorizer.c (slpeel_add_loop_guard): Fix types.
(set_prologue_iterations): Likewise.
* tree-vect-transform.c (vect_create_addr_base_for_vector_ref):
Likewise.
(vect_update_init_of_dr): Likewise.
* tree-ssa-forwprop.c (forward_propagate_addr_expr_1): Fix
type verification.
* fold-const.c (fold_unary): Do not generate calculations
in sub-types.
