re PR target/53914 (poor code generated for offset addressing on ppc32)
PR target/53914
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.
