        * config/bfin/bfin.c (workaround_speculation): Correct algorithm to
        not lose track of the number of NOPs needed.  Number of NOPs needed
        for sync vs. loads workaround was switched; corrected.  Run second
        pass for all workarounds.  No NOPs needed after call insns.  Change
        second pass to use find_next_insn_start and find_load helpers in order
        to properly detect parallel insns.
