Richard Guenther - Sept. 6, 2012, 11:40 a.m.
This removes the MOVE_NONTEMPORAL tree flag which is nowhere set.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

2012-09-06  Richard Guenther  <rguenther@suse.de>

	* tree.h (MOVE_NONTEMPORAL): Remove.
	* tree-pretty-print.c (dump_generic_node): Remove
	MOVE_NONTEMPORAL handling.
	* expr.c (expand_expr_real_1): Likewise.
