3009 (find_splittable_regs): Likewise. Only create one new pseudo
3010 if we have multiple address GIVs that were combined with the same
3011 dst_reg GIV. Note when a new register is created due to unrolling.
3012 * rtl.c (reg_note_name): Add REG_NOALIAS.
3013 * rtl.h (enum reg_note): Similarly.

3025 OPERAND_ADDRESS when computing how many registers an insn needs.
3026 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
3028 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
3030 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
3031 in reload_reg_use_in_op_addr do not reach the end.
3032 do not reach the end.
3033 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
3034 RELOAD_FOR_OPERAND_ADDRESS.
