                    307:        instruction, or have a clobbered register to load the large
                    308:        constant into.  This is instead of using $1 to hold the
                    309:        intermeidate value.  Set the safe attribute to yes for the cases
                    310:        where we need to load the integer.  Add define_split's to break
                    311:        the large logical operations into the separate pieces.

                   2780:        * cp-tree.h:  Add entry for $vb and $vf so that NO_DOLLAR_IN_LABEL
                   2781:        works.
                   2782:        * cp-class.c (finish_struct):  Use the new macros from cp-tree.h.

                   2794:        we're not inside a class anymore) just report an error rather than
                   2795:        crashing in popclass (if there wasn't a previous parse error, as the
                   2796:        message suggests, we should get reports; this closes gcc/p0000525.)

                   2802: 
                   2803:        Workaround for p869:
                   2804:         1) grokdeclarator (around cp-decl.c:7462) is using popclass(1)
                   2805:         uses popclass(1) to close the pushclass(3) done by
                   2806:         build_push_scope; however, it's coming around another time and
                   2807:         popping all the way out, which leads to the core dump when
                   2808:         do_friend is called from global scope (do_friend uses
                   2809:         current_class_name to figure out whose friendship it is
                   2810:         bestowing.) Current workaround: if (friendp) don't allow
                   2811:         popping all the way out. We still need to figure out how to
                   2812:         make sure it only gets called the *right* time; we also need
                   2813:         to figure out if the correct scope is being used, but that's a
                   2814:         matter of regression testing.
                   2815:

                   2820:        * cp-decl.c: Cleanup binding_levels_sane related code.  Deleted
                   2821:        argument, and changed to void type.  Removed extraneous asserts.
                   2822:

                   2830: 
                   2831:        * mips.c (output_movstrsi): If one of our temporary registers is
                   2832:        used as an address register, don't use it and emit a warning.  This
                   2833:        is a temporary measure.

                   2856:        registers; it resulted in poor code.

                   2858:        float->fix->float conversions.
                   2859:        * sparc.c (output_move_double): Clean up ldd/std code.  Don't emit

                   2881:        as that is what varasm.c does now.  This really maybe should go

                   2883:        maintainability.

                   2904:        constant so we don't convert negative values into positive values;
