12944 (find_splittable_regs): Likewise. Only create one new pseudo
12945 if we have multiple address GIVs that were combined with the same
12946 dst_reg GIV. Note when a new register is created due to unrolling.
12947 * rtl.c (reg_note_name): Add REG_NOALIAS.
12948 * rtl.h (enum reg_note): Similarly.
12949 (rtx_varies_p, may_trap_p, side_effects_p): Declare.
12950 (volatile_refs_p, volatile_insn_p, remove_note): Likewise.
12951 (note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
12952 (true_dependence, read_dependence, anti_dependence): Likewise.
12953 (output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
12954 (mark_user_reg, mark_reg_pointer): Likewise.
12957 * Integrate reload bugfix from Wilon which enables the PA port
12958 to bootstrap again.
12959 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
12960 OPERAND_ADDRESS when computing how many registers an insn needs.
12961 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
12963 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
12964 OPADDR_ADDR reload.
12965 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
12966 in reload_reg_use_in_op_addr do not reach the end.
12967 do not reach the end.
12968 (reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
12969 RELOAD_FOR_OPERAND_ADDRESS.
