ChangeLog:

2013-11-14  Ulrich Weigand  <Ulrich.Weigand@de.ibm.com>

	* config/rs6000/rs6000.c (rs6000_emit_prologue): Do not place a
	RTX_FRAME_RELATED_P marker on the UNSPEC_MOVESI_FROM_CR insn.
	Instead, add USEs of all modified call-saved CR fields to the
	insn storing the result to the stack slot, and provide an
	appropriate REG_FRAME_RELATED_EXPR for that insn.
	* config/rs6000/rs6000.md ("*crsave"): New insn pattern.
	* config/rs6000/predicates.md ("crsave_operation"): New predicate.
