[PATCH] Remove (duplicate) build_addr_strip_iref


This removes build_addr_strip_iref in favor of build_fold_addr_expr.

Bootstrapped and regtested on x86_64-unknown-linux-gnu.

Ok for mainline?

Richard.


2005-05-19  Richard Guenther  <rguenth@gcc.gnu.org>

	* tree-ssa-loop-ivopts.c (build_addr_strip_iref): Remove.
	(find_interesting_uses_address): Use build_fold_addr_expr instead.
	(strip_offset_1): Likewise.
	(tree_to_aff_combination): Likewise.
