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

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

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

3821 makefile wants. Put special vax stage1 options in
3822 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything

3831 warning options via a three level scheme so that -pedantic and
3832 -Wtraditional are not used for non-C front ends: LOOSE_WARN,
3833 STRICT1_WARN, STRICT2_WARN -> $(@D)-warn, GCC_WARN_CFLAGS ->

3837 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
3838 generation rules. Wrap all rules that change the current
3839 directory in parentheses; pmake doesn't spawn a new shell for
3840 each command. Expunge all references to $(P). When one
3841 command depends on another and they're run all at once, use &&
3842 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
3843 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
3846 * objc/Make-lang.in: Wrap all rules that change the current
3847 directory in parentheses. Expunge all references to $(P).
