        PR rtl-optimization/44919
        * sel-sched.c (move_cond_jump): Remove assert, check that
        the several blocks case can only happen with mutually exclusive
        insns instead.  Rewrite the movement code to support moving through
        several basic blocks.

        * g++.dg/opt/pr44919.C: New.
