        * sel-sched-ir.c (merge_history_vect): Factor out from ...
        (merge_expr_data): ... here.
        (av_set_intersect): Rename to av_set_code_motion_filter.
        Update all callers.  Call merge_history_vect when an
        expression is found in both sets.
        * sel-sched-ir.h (av_set_code_motion_filter): Add prototype.
