New Revision: 162390

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=162390
Log:
	PR bootstrap/44970
	PR middle-end/45009
	* postreload.c: Include "target.h".
	(reload_combine_closest_single_use): Don't take DEBUG_INSNs
	into account.
	(fixup_debug_insns): Don't copy the rtx.
	(reload_combine_recognize_const_pattern): DEBUG_INSNs can't
	have uses.  Don't copy when replacing.  Call fixup_debug_insns
	in the case where we merged one add with another.
	(reload_combine_recognize_pattern): Fail if there aren't any
	uses.  Try harder to determine whether we're picking a valid
	index register.  Don't set store_ruid for an insn we're going
	to scan in the next iteration.
	(reload_combine): Remove unused code.
	(reload_combine_note_use): When updating use information for
	an old insn, ignore a use that occurs after store_ruid.
	* Makefile.in (postreload.o): Update dependencies.
