12945 * combine.c (distribute_notes): Handle REG_NOALIAS.
12946 * cse.c (struct write_data): Delete. No longer needed.
12947 (invalidate): Don't call set_nonvarying_address_components anymore.
12948 Use true_dependence to decide if an entry should be removed from
12950 (invalidate_memory): Remove WRITES argument, simplify appropriately.
12952 (note_mem_written): Similarly for WRITE_PTR argument.
12953 (invalidate_from_clobbers): Similarly for W argument.
12954 (invalidate_for_call): Remove memory elements from the hash table.
12955 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
12956 (cse_rtx_varies_p): New function. Derived from old
12957 cse_rtx_addr_varies_p.
12958 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
12959 Don't call note_mem_written anymore. Stack pushes invalidate the stack
12960 pointer if PUSH_ROUNDING is defined. No longer need to call
12961 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
12962 (skipped_writes_memory): Remove variable.
12963 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
12964 (invalidate_skipped_block): Simplify for new alias analysis code.
12965 (cse_set_around_loop): Likewise.
12966 (cse_main): Call init_alias_analysis.
12967 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
12968 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
12969 (f_options): Add new alias checking arguments.
12970 (main): Set flag_alias_check when optimizing.
12971 * local_alloc (validate_equiv_mem_from_store): Add new arguments
12972 to true_dependence.
12973 (memref_referenced_p): Likewise.
12974 * loop.c (NUM_STORES): Increase to 30.
12975 (prescan_loop): Only non-constant calls set unknown_address_altered.
12976 (invariant_p): Add new arguments to true_dependence.
12977 (record_giv): Initialize unrolled and shared fields.
12978 (emit_iv_add_mult): Call record_base_value as needed.
12979 * loop.h (struct induction): Add unrolled and shared fields.
12980 * unroll.c (unroll_loop): Call record_base_value as needed.
12981 (copy_loop_body): Likewise.
12982 (final_biv_value): Likewise.
12983 (final_giv_value): Likewise.
12984 (find_splittable_regs): Likewise. Only create one new pseudo
12985 if we have multiple address GIVs that were combined with the same
12986 dst_reg GIV. Note when a new register is created due to unrolling.
12987 * rtl.c (reg_note_name): Add REG_NOALIAS.
12988 * rtl.h (enum reg_note): Similarly.
12989 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
12990 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
12991 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
12992 (true_dependence, read_dependence, anti_dependence): Likewise.
12993 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
12994 (mark_user_reg, mark_reg_pointer): Likewise.
12997 * Integrate reload bugfix from Wilon which enables the PA port
12998 to bootstrap again.
12999 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
13000 OPERAND_ADDRESS when computing how many registers an insn needs.
13001 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
13003 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
13004 OPADDR_ADDR reload.
13005 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
13006 in reload_reg_use_in_op_addr do not reach the end.
13007 do not reach the end.
13008 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
13009 RELOAD_FOR_OPERAND_ADDRESS.
