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

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

371 reference type. This loses type information (breaking GDB's
372 `ptype' command, among other things) just to describe a location
373 which stabs can represent correctly in other ways.

422 (WINT_TYPE, INTMAX_TYPE, UINTMAX_TYPE): Define.
423 (c_common_nodes_and_builtins): Create string_type_node,
424 const_string_type_node, wint_type_node, intmax_type_node,
