8217 (true_dependence, read_dependence, anti_dependence): Likewise.
8218 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
8219 (mark_user_reg, mark_reg_pointer): Likewise.
8222 * Integrate reload bugfix from Wilon which enables the PA port
8224 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
8225 OPERAND_ADDRESS when computing how many registers an insn needs.
8226 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
8228 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
8230 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
8231 in reload_reg_use_in_op_addr do not reach the end.
8232 do not reach the end.
8233 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
8234 RELOAD_FOR_OPERAND_ADDRESS.
