7778 (schedule_insns): Always call init_alias_analysis.
7779 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
7780 mark return value from such functions as a pointer and keep track of
7781 them for alias analysis. If a return value from a function is a
7782 pointer, mark it as such.
7783 * combine.c (distribute_notes): Handle REG_NOALIAS.
7784 * cse.c (struct write_data): Delete. No longer needed.
7785 (invalidate): Don't call set_nonvarying_address_components anymore.
7786 Use true_dependence to decide if an entry should be removed from
7788 (invalidate_memory): Remove WRITES argument, simplify appropriately.
7790 (note_mem_written): Similarly for WRITE_PTR argument.
7791 (invalidate_from_clobbers): Similarly for W argument.

7795 cse_rtx_addr_varies_p.
7796 (cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
7797 Don't call note_mem_written anymore. Stack pushes invalidate the stack
7798 pointer if PUSH_ROUNDING is defined. No longer need to call
7799 cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
7800 (skipped_writes_memory): Remove variable.
7801 (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
7802 (invalidate_skipped_block): Simplify for new alias analysis code.

7821 (final_giv_value): Likewise.
7822 (find_splittable_regs): Likewise. Only create one new pseudo
7823 if we have multiple address GIVs that were combined with the same
7824 dst_reg GIV. Note when a new register is created due to unrolling.
7825 * rtl.c (reg_note_name): Add REG_NOALIAS.
7826 * rtl.h (enum reg_note): Similarly.
7827 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
7828 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.

7832 (mark_user_reg, mark_reg_pointer): Likewise.
7835 * Integrate reload bugfix from Wilon which enables the PA port
7837 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
7838 OPERAND_ADDRESS when computing how many registers an insn needs.
7839 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
7841 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
7843 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
7844 in reload_reg_use_in_op_addr do not reach the end.
7845 do not reach the end.
7846 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
7847 RELOAD_FOR_OPERAND_ADDRESS.
