Once OSF/1 and IRIX are gone, I hope all of the ECOFF/mdebug debug format support can go as well (mipsread.c, mdebugread.c etc.) ... The process documented in the Wiki is a bit weird (adding OBSOLETE to *every line* of those files ???) and it seems we didn't follow it in the last major round of obsoleting code either: https://sourceware.org/ml/gdb-announce/2007/msg00000.html I think using a process along similar lines might be best.
