775 Move some of the setup code into schedule_region. Get head/tail
776 from current_sched_info, and update it when done.
777 (schedule_region): Slightly rearranged, some code moved here from
778 schedule_block. Call no_real_insns_p to avoid doing work for a
779 block that consists only of notes and labels.

912 (*tablejump_rjmp, *tablejump_lib, *tablejump_enh, *tablejump):
913 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
914 MEM for program memory word reference. Do not add the label to
915 the table index in each of the asm output templates, instead ...

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

4320 makefile wants. Put special vax stage1 options in
4321 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything
4322 with extra_c_objs, extra_cxx_objs, or extra_cpp_objs.

4330 warning options via a three level scheme so that -pedantic and
4331 -Wtraditional are not used for non-C front ends: LOOSE_WARN,
4332 STRICT1_WARN, STRICT2_WARN -> $(@D)-warn, GCC_WARN_CFLAGS ->

4336 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
4337 generation rules. Wrap all rules that change the current
4338 directory in parentheses; pmake doesn't spawn a new shell for
4339 each command. Expunge all references to $(P). When one
4340 command depends on another and they're run all at once, use &&
4341 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
4342 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
