4801 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
4802 mark return value from such functions as a pointer and keep track of
4803 them for alias analysis. If a return value from a function is a
4804 pointer, mark it as such.
4805 * combine.c (distribute_notes): Handle REG_NOALIAS.
4806 * cse.c (struct write_data): Delete. No longer needed.
4807 (invalidate): Don't call set_nonvarying_address_components anymore.
4808 Use true_dependence to decide if an entry should be removed from
4810 (invalidate_memory): Remove WRITES argument, simplify appropriately.
4812 (note_mem_written): Similarly for WRITE_PTR argument.
4813 (invalidate_from_clobbers): Similarly for W argument.
4814 (invalidate_for_call): Remove memory elements from the hash table.
4815 (refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
4816 (cse_rtx_varies_p): New function. Derived from old
4817 cse_rtx_addr_varies_p.
4818 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
4819 Don't call note_mem_written anymore. Stack pushes invalidate the stack
4820 pointer if PUSH_ROUNDING is defined. No longer need to call
4821 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
4822 (skipped_writes_memory): Remove variable.
4823 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
4824 (invalidate_skipped_block): Simplify for new alias analysis code.
4825 (cse_set_around_loop): Likewise.
4826 (cse_main): Call init_alias_analysis.
4827 * flags.h (flag_alias_check, flag_argument_noalias): Declare.
4828 * toplev.c (flag_alias_check, flag_argument_noalias): Define.
4829 (f_options): Add new alias checking arguments.
4830 (main): Set flag_alias_check when optimizing.
4831 * local_alloc (validate_equiv_mem_from_store): Add new arguments
4833 (memref_referenced_p): Likewise.
4834 * loop.c (NUM_STORES): Increase to 30.
4835 (prescan_loop): Only non-constant calls set unknown_address_altered.
4836 (invariant_p): Add new arguments to true_dependence.
4837 (record_giv): Initialize unrolled and shared fields.
4838 (emit_iv_add_mult): Call record_base_value as needed.
4839 * loop.h (struct induction): Add unrolled and shared fields.
4840 * unroll.c (unroll_loop): Call record_base_value as needed.
4841 (copy_loop_body): Likewise.
4842 (final_biv_value): Likewise.
4843 (final_giv_value): Likewise.
4844 (find_splittable_regs): Likewise. Only create one new pseudo
4845 if we have multiple address GIVs that were combined with the same
4846 dst_reg GIV. Note when a new register is created due to unrolling.
4847 * rtl.c (reg_note_name): Add REG_NOALIAS.
4848 * rtl.h (enum reg_note): Similarly.
4849 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
4850 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
4851 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
4852 (true_dependence, read_dependence, anti_dependence): Likewise.
4853 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
4854 (mark_user_reg, mark_reg_pointer): Likewise.
4857 * Integrate reload bugfix from Wilon which enables the PA port
4859 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
4860 OPERAND_ADDRESS when computing how many registers an insn needs.
4861 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
4863 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
4865 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
4866 in reload_reg_use_in_op_addr do not reach the end.
4867 do not reach the end.
4868 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
4869 RELOAD_FOR_OPERAND_ADDRESS.
