3831 if we have multiple address GIVs that were combined with the same
3832 dst_reg GIV. Note when a new register is created due to unrolling.
3833 * rtl.c (reg_note_name): Add REG_NOALIAS.
3834 * rtl.h (enum reg_note): Similarly.
3835 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
3836 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
3837 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
3838 (true_dependence, read_dependence, anti_dependence): Likewise.
3839 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
3840 (mark_user_reg, mark_reg_pointer): Likewise.
3843 * Integrate reload bugfix from Wilon which enables the PA port
3845 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
3846 OPERAND_ADDRESS when computing how many registers an insn needs.
3847 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
3849 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
3851 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
3852 in reload_reg_use_in_op_addr do not reach the end.
3853 do not reach the end.
3854 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
3855 RELOAD_FOR_OPERAND_ADDRESS.
