10146 dst_reg GIV. Note when a new register is created due to unrolling.
10147 * rtl.c (reg_note_name): Add REG_NOALIAS.
10148 * rtl.h (enum reg_note): Similarly.
10149 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
10150 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
10151 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
10152 (true_dependence, read_dependence, anti_dependence): Likewise.
10153 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
10154 (mark_user_reg, mark_reg_pointer): Likewise.
10157 * Integrate reload bugfix from Wilon which enables the PA port
10158 to bootstrap again.
10159 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
10160 OPERAND_ADDRESS when computing how many registers an insn needs.
10161 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
10163 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
10164 OPADDR_ADDR reload.
10165 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
10166 in reload_reg_use_in_op_addr do not reach the end.
10167 do not reach the end.
10168 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
10169 RELOAD_FOR_OPERAND_ADDRESS.
