--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Steven Sun from comment #3) > By the way, does anyone know other magics like g:hash? rNNNN works for the old Subversion revisions "PRNNNN" and "bug NNNN" (maybe one more) puts a link to the other bug. rN-NNNN (and rN-NNNN-HHHHH) works if you know the new scheme of git revisions (git gcc-descr can find that for you and you can undo them with gcc-undescr) I think those are all of the ones which we added to bugzilla, everything else is standard (e.g. comment #0 works).
