New Revision: 128753

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=128753
Log:
	* config/rs6000/rs6000.c (rs6000_emit_sync): For QI or HI mode
	used_m, even if it is 32-bit aligned, adjust used_m MEM to have
	SImode and update m.  Don't run gen_lowpart_common on arbitrary
	memory address, force it to register first.

	* gcc.dg/sync-2.c (AI_ALIGN): Define if not defined.
	(AI): Add AI_ALIGN.
	* gcc.dg/sync-3.c: New test.
