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

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

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

3822 * recog.c (preprocess_constraints) [case 'p']: Set it.
3824 2000-10-27 Zack Weinberg <zack@wolery.stanford.edu>
3826 * configure.in: If not NO_MINUS_C_MINUS_O, substitute

3830 $outputs. Do not run configure.lang from config.status.
3831 Rearrange warning-flag logic to correspond to what the
3832 makefile wants. Put special vax stage1 options in
3833 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything
3834 with extra_c_objs, extra_cxx_objs, or extra_cpp_objs.

3842 warning options via a three level scheme so that -pedantic and
3843 -Wtraditional are not used for non-C front ends: LOOSE_WARN,
3844 STRICT1_WARN, STRICT2_WARN -> $(@D)-warn, GCC_WARN_CFLAGS ->
3845 WARN_CFLAGS. Distinguish STAGE1_CFLAGS from BOOT_CFLAGS.
3846 Add -I$(@D) and -I$(srcdir)/$(@D) to INCLUDES.
3847 Set OUTPUT_OPTION, ZLIB, ZLIBINC. Do not set P,
3848 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
3849 generation rules. Wrap all rules that change the current
3850 directory in parentheses; pmake doesn't spawn a new shell for
3851 each command. Expunge all references to $(P). When one
3852 command depends on another and they're run all at once, use &&
3853 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
3854 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
3857 * objc/Make-lang.in: Wrap all rules that change the current
3858 directory in parentheses. Expunge all references to $(P).
