Wikipedia says that VAX production ceased in 2005. The last VAX-specific patch I can see being submitted to gdb-patches is us mentioning support for VAX floats in the Ada mode (which we removed in 2010). VAX VMS was removed in 2010 from BFD. There seems to be some regular activity around VAX on the GCC side, though, but Ultrix itself seems to be no longer be supported. So this seems to indicate that we will be able to remove support for Ultrix. > Below's the table I was building, listing the full set of > supported hosts, according to configure.host, mapping OS to triplet. > | HP-UX | hppa*-*-hpux* | > | HP-UX | ia64-*-hpux* | I suspect that HP-UX will no longer find any takers. AdaCore had to step-up many many years go to keep those alive. The situation is different today, and we are stepping down. -- Joel
