7774 (schedule_insns): Always call init_alias_analysis.
7775 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
7776 mark return value from such functions as a pointer and keep track of
7777 them for alias analysis. If a return value from a function is a
7778 pointer, mark it as such.
7779 * combine.c (distribute_notes): Handle REG_NOALIAS.
7780 * cse.c (struct write_data): Delete. No longer needed.
7781 (invalidate): Don't call set_nonvarying_address_components anymore.
7782 Use true_dependence to decide if an entry should be removed from
7784 (invalidate_memory): Remove WRITES argument, simplify appropriately.
7786 (note_mem_written): Similarly for WRITE_PTR argument.
7787 (invalidate_from_clobbers): Similarly for W argument.

7792 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
7793 Don't call note_mem_written anymore. Stack pushes invalidate the stack
7794 pointer if PUSH_ROUNDING is defined. No longer need to call
7795 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
7796 (skipped_writes_memory): Remove variable.
7797 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.

7817 (final_giv_value): Likewise.
7818 (find_splittable_regs): Likewise. Only create one new pseudo
7819 if we have multiple address GIVs that were combined with the same
7820 dst_reg GIV. Note when a new register is created due to unrolling.
7821 * rtl.c (reg_note_name): Add REG_NOALIAS.
7822 * rtl.h (enum reg_note): Similarly.
7823 (rtx_varies_p, may_trap_p, side_effects_p): Declare.

7833 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
7834 OPERAND_ADDRESS when computing how many registers an insn needs.
7835 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
7837 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
7839 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
7840 in reload_reg_use_in_op_addr do not reach the end.
7841 do not reach the end.
7842 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
7843 RELOAD_FOR_OPERAND_ADDRESS.
