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

908 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
909 invisible reference in registers, but then spilled to the stack.
910 Remove code to emit a second stab for such parameters; it attempts
911 to describe the value's location by introducing a synthetic C++
912 `reference' type, and then saying the stack slot has that
913 reference type. This loses type information (breaking GDB's
914 `ptype' command, among other things) just to describe a location
915 which stabs can represent correctly in other ways.
