Author: bernds Date: Mon Aug 2 10:06:47 2010 New Revision: 162815 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=162815 Log: 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. testsuite/ PR target/40457 * gcc.target/arm/pr40457-1.c: New test. * gcc.target/arm/pr40457-2.c: New test.
