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

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

935 (WINT_TYPE, INTMAX_TYPE, UINTMAX_TYPE): Define.
936 (c_common_nodes_and_builtins): Create string_type_node,
937 const_string_type_node, wint_type_node, intmax_type_node,
