        PR middle-end/66133
        * omp-low.c (expand_omp_taskreg): For GIMPLE_OMP_TASK expansion,
        make sure it is never noreturn, even when the task body does not
        return.
        (lower_omp_taskreg): For GIMPLE_OMP_TASK, emit GIMPLE_OMP_CONTINUE
        right before GIMPLE_OMP_RETURN.
        * tree-cfg.c (make_edges): Accept GIMPLE_OMP_CONTINUE as ->cont
        for GIMPLE_OMP_TASK.  For GIMPLE_OMP_RETURN corresponding to
        GIMPLE_OMP_TASK add an EDGE_ABNORMAL edge from entry to exit.

        * testsuite/libgomp.c/pr66133.c: New test.
