        PR debug/65779
        * shrink-wrap.c: Include valtrack.h.
        (move_insn_for_shrink_wrap): Add DEBUG argument.  If
        MAY_HAVE_DEBUG_INSNS, call dead_debug_add on DEBUG_INSNs
        in between insn and where it will be moved to.  Call
        dead_debug_insert_temp.
        (prepare_shrink_wrap): Adjust caller.  Call dead_debug_local_init
        first and dead_debug_local_finish at the end.
        For uses and defs bitmap, handle all regs in between REGNO and
        END_REGNO, not just the first one.

        * gcc.dg/pr65779.c: New test.
