    * config/pa/pa.c (branch_to_delay_slot_p): Use next_active_insn instead
    of next_real_insn.  Search forward checking for both ASM_INPUT and
    ASM_OPERANDS asms until exit condition is found.
    (branch_needs_nop_p): Likewise.
    (use_skip_p): New function.
    (output_cbranch): Use use_skip_p.
    (output_bb, output_bvb): Likewise.
