* 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.
