5272 (final_biv_value): Likewise.
5273 (final_giv_value): Likewise.
5274 (find_splittable_regs): Likewise. Only create one new pseudo
5275 if we have multiple address GIVs that were combined with the same
5276 dst_reg GIV. Note when a new register is created due to unrolling.
5277 * rtl.c (reg_note_name): Add REG_NOALIAS.
5278 * rtl.h (enum reg_note): Similarly.
5279 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
5280 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
5281 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
5282 (true_dependence, read_dependence, anti_dependence): Likewise.
5283 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
5284 (mark_user_reg, mark_reg_pointer): Likewise.
5287 * Integrate reload bugfix from Wilon which enables the PA port
5289 * reload1.c (reload): Sum needs for both OPADDR_ADDR and and
5290 OPERAND_ADDRESS when computing how many registers an insn needs.
5291 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
5293 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
5295 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
5296 in reload_reg_use_in_op_addr do not reach the end.
5297 do not reach the end.
5298 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
5299 RELOAD_FOR_OPERAND_ADDRESS.
