734 Move some of the setup code into schedule_region. Get head/tail
735 from current_sched_info, and update it when done.
736 (schedule_region): Slightly rearranged, some code moved here from
737 schedule_block. Call no_real_insns_p to avoid doing work for a

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

970 (c_common_nodes_and_builtins): Create string_type_node,
