Please install on the trunk. hmz, according to https://www.debian.org/ports/netbsd/ the debian knetbsd port is abandoned since about 2002. If this is true (please confirm) then we should probably remove knetbsd from - upstream config repo - GCC - binutils-gdb instead of the above patchlet. This would work equally well for me WRT config-list.mk builds.. [I should have checked this earlier, sorry..] > > THanks, > Jeff >

Actually that page refers to the GNU/NetBSD port, which was based on NetBSD's libc, the GNU/kNetBSD port (based on glibc), was started at the same time as GNU/kFreeBSD but was short-lived and put into hibernation to try to focus the effort on GNU/kFreeBSD. But that has been a very long winter… > If this is true (please confirm) then we should probably remove knetbsd from > - upstream config repo > - GCC > - binutils-gdb The difference between removing support in the toolchain and in the upstream config repo is that for the former it will just need forward porting the patches, but for the latter it takes a very long time and lots of prodding to get upstream projects to update to current config.* scripts. (In Debian we have been switching to always update the config.* scripts at build time so it would probably not be too bad going forward for us, but it would when using projects directly from upstream.) Although I always find it a bit sad to remove ports support, I have the impression the GNU/kNetBSD port is not coming to live any time soon. So you might want to wait a bit for comments from others, perhaps someone has been working on such port that we are not aware of, but otherwise I think removal would be fine. Thanks, Guillem

It's often the case that we mark it as deprecated and issue an explicit error if someone tries to build the port. That seems wise here. jeff

That seems wise here. I will apply the abovementioned patch ASAP and let somebody else with janitorial spare cleanup cycles propose removal of *-knetbsd-* then. Given previous discussion in https://gcc.gnu.org/ml/gcc-patches/2015-04/msg00582.html someone may also be in a position to remove *-openbsd3-* support, FWIW. I personally cannot take care of these due to limited (essentially non-existing ;) spare time. Same, BTW for Ultrix support which was officially removed from GCC last cycle, IIRC -- unless config entries are meant to be sticky from a GNU tool chain support POV per design/decision? Either way, cannot clean these up properly ATM and not familiar with those policies, so punting for now.. Cheers, > >jeff

I'll try to get to it before the end of stage 1. Its pretty easy really, you just add the triple you want to obsolete to the switch in config.gcc at about line 240, and then wait for the next release. btw thanks for cleaning up config-list.mk :) > Same, BTW for Ultrix support which was officially removed from GCC last cycle, IIRC -- unless config entries are meant to be sticky from a GNU tool chain support POV per design/decision? It looks like most of the ultrix references are in config.guess / config.sub / configure so from upstream repositories. THere's a few references in gcc/doc/ that could probably be cleaned up, and a little bit of something in fixincludes I think.
