	* rtl.h (struct rtx_def): Add comment for field jump.
	(SUBREG_MATCH_RELOAD_P): New macro.
	* lra-constraints.c (curr_insn_set): New.
	(match_reload): Use SUBREG_MATCH_RELOAD_P.
	(check_and_process_move): Use curr_insn_set.  Process only single
	set insns.  Don't initialize sec_mem_p and change_p.
	(simplify_operand_subreg): Check SUBREG_MATCH_RELOAD_P.
	(process_alt_operands): Use #if HAVE_ATTR_enabled instead of
	#ifdef.  Add code to remove cycling.
	(process_address): Process even if non-null disp.  Reload inner
	instead of disp when base and index are null.
	(curr_insn_transform): Initialize sec_mem_p and change_p.  Set up
	curr_insn_set.  Call check_and_process_move only for single set
	insns.
