r152769 - in /branches/reload-v2/gcc: ChangeLog...


Author: law
Date: Wed Oct 14 14:56:32 2009
New Revision: 152769

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=152769
Log:
	* ira-reload.c (no_uses_after_last_set): New bitmap.
	(identify_singleton_sets): Set it appropriately.
	(emit_localizing_stores): More aggressively replace a pseudo
	with its equivalent memory location.  Indicate that INSN
	should be deleted in certain cases.
	(localize_pseudos): Allocate and free no_uses_after_last_set.
	Fix SET/USE processing order for no_uses_after_last_set.
	If emit_localizing_stores requests an insn be deleted, do it.
Another tiny space/speed improvement
