4319 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
4320 Don't call note_mem_written anymore. Stack pushes invalidate the stack
4321 pointer if PUSH_ROUNDING is defined. No longer need to call
4322 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
4323 (skipped_writes_memory): Remove variable.
4324 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
4325 (invalidate_skipped_block): Simplify for new alias analysis code.
4326 (cse_set_around_loop): Likewise.
4327 (cse_main): Call init_alias_analysis.
4328 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
4329 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
4330 (f_options): Add new alias checking arguments.
4331 (main): Set flag_alias_check when optimizing.
4332 * local_alloc (validate_equiv_mem_from_store): Add new arguments
4334 (memref_referenced_p): Likewise.
4335 * loop.c (NUM_STORES): Increase to 30.
4336 (prescan_loop): Only non-constant calls set unknown_address_altered.
4337 (invariant_p): Add new arguments to true_dependence.
4338 (record_giv): Initialize unrolled and shared fields.
4339 (emit_iv_add_mult): Call record_base_value as needed.
4340 * loop.h (struct induction): Add unrolled and shared fields.
4341 * unroll.c (unroll_loop): Call record_base_value as needed.
4342 (copy_loop_body): Likewise.
4343 (final_biv_value): Likewise.
4344 (final_giv_value): Likewise.
4345 (find_splittable_regs): Likewise. Only create one new pseudo
4346 if we have multiple address GIVs that were combined with the same
4347 dst_reg GIV. Note when a new register is created due to unrolling.
4348 * rtl.c (reg_note_name): Add REG_NOALIAS.
4349 * rtl.h (enum reg_note): Similarly.
4350 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
4351 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
4352 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
4353 (true_dependence, read_dependence, anti_dependence): Likewise.
4354 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
4355 (mark_user_reg, mark_reg_pointer): Likewise.
4358 * Integrate reload bugfix from Wilon which enables the PA port
4360 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
4361 OPERAND_ADDRESS when computing how many registers an insn needs.
4362 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
4364 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
4366 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
4367 in reload_reg_use_in_op_addr do not reach the end.
4368 do not reach the end.
4369 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
4370 RELOAD_FOR_OPERAND_ADDRESS.
