        * sel-sched-ir (sel_init_new_insn): New parameter old_seqno.
        Default it to -1.  Pass it down to init_simplejump_data.
        (init_simplejump_data): New parameter old_seqno.  Pass it down
        to get_seqno_for_a_jump.
        (get_seqno_for_a_jump): New parameter old_seqno.  Use it for
        initializing new jump seqno as a last resort.  Add comment.
        (sel_redirect_edge_and_branch): Save old seqno of the conditional
        jump and pass it down to sel_init_new_insn.
        (sel_redirect_edge_and_branch_force): Likewise.

	* gcc.dg/pr60866.c: New test.
