677 from current_sched_info, and update it when done.
678 (schedule_region): Slightly rearranged, some code moved here from
679 schedule_block. Call no_real_insns_p to avoid doing work for a

855 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
856 invisible reference in registers, but then spilled to the stack.
857 Remove code to emit a second stab for such parameters; it attempts
858 to describe the value's location by introducing a synthetic C++

860 reference type. This loses type information (breaking GDB's
861 `ptype' command, among other things) just to describe a location
