1221 if we have multiple address GIVs that were combined with the same
1222 dst_reg GIV. Note when a new register is created due to unrolling.
1223 * rtl.c (reg_note_name): Add REG_NOALIAS.

1233 * Integrate reload bugfix from Wilon which enables the PA port
5fa39bfe
JL		 1234 to bootstrap again.
1235 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
1236 OPERAND_ADDRESS when computing how many registers an insn needs.
1237 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
1238 conflict.
1239 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
1240 OPADDR_ADDR reload.
1241 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers

1243 do not reach the end.
1244 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
1245 RELOAD_FOR_OPERAND_ADDRESS.
