	PR target/54009
	* config/rs6000/constraints.md (Y): Use mem_operand_gpr.
	* config/rs6000/predicates.md (word_offset_memref_operand): Delete.
	Adjust all rs6000_legitimate_offset_address_p calls.
	* config/rs6000/rs6000-protos.h (mem_operand_gpr): Declare.
	(rs6000_secondary_reload_gpr): Declare.
	(rs6000_legitimate_offset_address_p): Update prototype.
	(rs6000_offsettable_memref_p): Delete.
	(rs6000_secondary_reload_ppc64): Delete.
	* config/rs6000/rs6000.c (address_offset): New function.
	(mem_operand_gpr): Likewise.
	(rs6000_legitimate_offset_address_p): Add worst_case param.  When
	not worst_case assume class of regs with least restrictive offsets.
	Adjust all calls.
	(legitimate_lo_sum_address_p): Simplify register mode tests.
	(rs6000_legitimize_address): Likewise.  Assume best case offset
	addressing.  Combine ELF and MACHO lo_sum code.
	(rs6000_mode_dependent_address): Correct offset addressing limits.
	(rs6000_offsettable_memref_p): Make static, add reg_mode param.
	Use reg_mode to help rs6000_legitimate_offset_address_p.
	(rs6000_secondary_reload): Use address_offset.  Handle 32-bit multi
	gpr load/store when offset too large.
	(rs6000_secondary_reload_gpr): Renamed rs6000_secondary_reload_ppc64.
	(rs6000_split_multireg_move): Adjust rs6000_offsettable_memref_p calls.
	* config/rs6000/rs6000.md (movdf_hardfloat32): Use 'Y' constraint
	for gpr load/store.  Order alternatives as r->Y,Y->r,r->r and
	d->m,m->d,d->d.  Correct size of gpr load/store.
	(movdf_softfloat32): Use 'Y' constraint for gpr load/store.  Order
	alternatives.
	(movti_ppc64): Likewise.
	(movdi_internal32): Likewise.  Also disparage fprs.
	(movdi_mfpgpr, movdi_internal64): Likewise.
	(movtf_internal): Use 'm' for fpr load/store.  Order alternatives.
	(movtf_softfloat): Order alternatives.
	(extenddftf2_internal): Use 'm' and 'Y' for store.
	(movti_power, movti_string): Use 'Y' for gpr load/store.  Order.
	(stack_protect_setdi, stack_protect_testdi): Likewise.
	(movdf_hardfloat64_mfpgpr, movdf_hardfloat64): Order alternatives.
	(movdf_softfloat64): Likewise.
	(reload_<mode>_store): Adjust reload_di_store to provide
	reload_si_store as well.
	(reload_<mode>_load): Likewise.
