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

416 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
417 MEM for program memory word reference. Do not add the label to
418 the table index in each of the asm output templates, instead ...

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

3842 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
3843 generation rules. Wrap all rules that change the current
3844 directory in parentheses; pmake doesn't spawn a new shell for
3845 each command. Expunge all references to $(P). When one
3846 command depends on another and they're run all at once, use &&
