Removing the LDC compiler from ppc64el / IEEE quad ABI support?
[ Please keep me in CC, I am not subscribed to this list ] Hi! I was investigating issue #907239 (LDC ftbfs on ppc64el), filing an upstream issue for it[1]. Upstream now suggests to drop support for the powerpc/ppc64el architecture entirely, due to the maintenance cost and the fact the issue won't likely be solved soon. However, they might support ppc64el again it in case the architecture switched to IEEE quad ABI. Is that likely to happen anytime soon in Debian by default? Cheers, Matthias [1]: https://github.com/ldc-developers/ldc/issues/2824 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907239 -- I welcome VSRE emails. See http://vsre.info/

Hmm, ok. I was aware of that package being for powerpc, which is not a release-arch. The upload is just for completeness - as for many other d-i packages, to update the alioth URLs in debian/control to Salsa: yaboot-installer (1.1.40) unstable; urgency=medium * Team upload [ Cyril Brulebois ] * Update Vcs-{Browser,Git} to point to salsa (alioth's replacement). -- Holger Wansing Mon, 27 Aug 2018 19:37:28 +0200 Which looked to me as a change of no harm.

I should let you know that cleaning out the modules from many many build revisions also lightens the disk load under /lib/modules. Dennis

It could be that a module in the kernel got split into two and hence the Debian kernel configuration needs to be updated. Again, if upstream makes some changes, it’s our duty in Debian to adapt these changes by updating our configuration. It can also be a bug, of course. > If it is a bug, it’s a minor one, and it’s easily worked around by the > addition to /etc/modules. But I’m curious to know what changed?

So… Why? Adrian hinted that it has something to do with a name change, but I’m unable to figure out what that change could be??? If it is a bug, it’s a minor one, and it’s easily worked around by the addition to /etc/modules. But I’m curious to know what changed? If it is a name change, as Adrian suggests, I’m curious to know what changed and why it was changed…
