re PR target/40457 (use stm and ldm to access consecutive memory words)
PR target/40457
* config/arm/arm.h (arm_regs_in_sequence): Declare.
* config/arm/arm-protos.h (emit_ldm_seq, emit_stm_seq,
load_multiple_sequence, store_multiple_sequence): Delete
declarations.
(arm_gen_load_multiple, arm_gen_store_multiple): Adjust
declarations.
* config/arm/ldmstm.md: New file.
* config/arm/arm.c (arm_regs_in_sequence): New array.
(load_multiple_sequence): Now static. New args SAVED_ORDER,
CHECK_REGS. All callers changed.
If SAVED_ORDER is nonnull, copy the computed order into it.
If CHECK_REGS is false, don't sort REGS. Handle Thumb mode.
(store_multiple_sequence): Now static. New args NOPS_TOTAL,
SAVED_ORDER, REG_RTXS and CHECK_REGS. All callers changed.
If SAVED_ORDER is nonnull, copy the computed order into it.
If CHECK_REGS is false, don't sort REGS. Set up REG_RTXS just
like REGS. Handle Thumb mode.
(arm_gen_load_multiple_1): New function, broken out of
arm_gen_load_multiple.
(arm_gen_store_multiple_1): New function, broken out of
arm_gen_store_multiple.
(arm_gen_multiple_op): New function, with code from
arm_gen_load_multiple and arm_gen_store_multiple moved here.
(arm_gen_load_multiple, arm_gen_store_multiple): Now just
wrappers around arm_gen_multiple_op. Remove argument UP, all callers
changed.
(gen_ldm_seq, gen_stm_seq, gen_const_stm_seq): New functions.
* config/arm/predicates.md (commutative_binary_operator): New.
(load_multiple_operation, store_multiple_operation): Handle more
variants of these patterns with different starting offsets. Handle
Thumb-1.
* config/arm/arm.md: Include "ldmstm.md".
(ldmsi_postinc4, ldmsi_postinc4_thumb1, ldmsi_postinc3, ldmsi_postinc2,
ldmsi4, ldmsi3, ldmsi2, stmsi_postinc4, stmsi_postinc4_thumb1,
stmsi_postinc3, stmsi_postinc2, stmsi4, stmsi3, stmsi2 and related
peepholes): Delete.
* config/arm/ldmstm.md: New file.
* config/arm/arm-ldmstm.ml: New file.
