Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think ia64 uses registers up to r127. As http://gcc.gnu.org/r999 is from mid 1992, it is very unlikely too many bugzilla comments would like to refer to those commits and can use the URL syntax in that case, so I think just linkifying only r followed by 4+ digits would be best.
