	(lra-eliminate): Ditto.
	* lra.c (lra_invalidate_insn_data): Set sp_offset.
	(setup_sp_offset): New.
	(lra_process_new_insns): Call setup_sp_offset.
	(lra): Add argument to lra_eliminate calls.
	* lra-constraints.c (get_equiv_substitution): Rename to get_equiv.
	(get_equiv_with_elimination): New.
	(process_addr_reg): Call get_equiv_with_elimination instead of
	get_equiv_substitution.

	(loc_equivalence_callback, lra_constraints): Ditto.
	(curr_insn_transform): Ditto.  Print the sp offset
	(process_alt_operands): Prevent stack pointer reloads.
	(lra_constraints): Remove one argument from lra_eliminate call.
	Move it up.  Mark used hard regs bfore it.  Use
	get_equiv_with_elimination instead of get_equiv_substitution.
	* lra-eliminations.c (lra_eliminate_regs_1): Add parameter and
	assert for param values combination.  Use sp offset.  Add argument
	to lra_eliminate_regs_1 calls.
	(lra_eliminate_regs): Add argument to lra_eliminate_regs_1 call.
	(curr_sp_change): New static var.
	(mark_not_eliminable): Add parameter.  Update curr_sp_change.
	Don't prevent elimination to sp if we can calculate its change.
	Pass the argument to mark_not_eliminable calls.
	(eliminate_regs_in_insn): Add a parameter.  Use sp offset.  Add
	argument to lra_eliminate_regs_1 call.
	(update_reg_eliminate): Move calculation of hard regs for spill
	lower.  Switch off lra_in_progress temporarily to generate regs
	involved into elimination.
	(lra_init_elimination): Rename to init_elimination.  Make it
	static.  Set up insn sp offset, check the offsets at the end of
	BBs.
	(process_insn_for_elimination): Add parameter.  Pass its value to
	eliminate_regs_in_insn.
	(lra_eliminate): : Add parameter.  Pass its value to
	process_insn_for_elimination.  Add assert for param values
	combination.  Call init_elimination.  Don't update offsets in
	equivalence substitutions.
	* lra-spills.c (assign_mem_slot): Don't call lra_eliminate_regs_1
	for created stack slot.
	(remove_pseudos): Call lra_eliminate_regs_1 before changing memory
	onto stack slot.
