New kit, lllvm-kit now added. It consist of small numbers of ebuilds that are directly related to the sys-devel/llvm. The rationale behind this is that ebuilds for llvm had no update for very long time and are problematic to maintain due to those ebuilds were spread all over different kits. Now they are from one kit. This kit is enabled by default and involves following update steps: ego sync emerge -C llvm:0 clang:0 emerge -1 llvm mesa emerge -auDN @world emerge @preserved-rebuild

I'm working on a new funtoo install on an older core2 machine, running nicely so far, but I can't seem to rebuild sys-devel/llvm-3.9.1 or sys-devel/llvm-3.9.1-r1. Oddly, I was somehow able to build this version initially, but am now having segfaults in which the emerge fails with (e.g.), /var/tmp/portage/sys-devel/llvm-3.9.1/work/llvm-3.9.1.src/include/llvm/ADT/iterator.h:178:73: internal compiler error: Segmentation fault I've posted more of the tail of the build.log here: https://dolomit.geo.uni-bremen.de/owncloud/index.php/s/7kfsyL9faRQhCaI The message asks that I Please submit a full bug report, with preprocessed source if appropriate. See <http://bugs.funtoo.org> for instructions." but I wanted to inquire if anyone had any suggestions before proceeding. I've tried rebuilding several times (also tried setting MAKEOPTS="-j1"), always failing, although not necessarily at the same place. My funtoo profile is # epro show === Enabled Profiles: === arch: x86-64bit build: current subarch: core2_64 flavor: server mix-ins: kde-plasma-5 mix-ins: console-extras mix-ins: dvd mix-ins: print === All inherited flavors from server flavor: === core (from server flavor) minimal (from core flavor) and /etc/make.conf is fairly empty: MAKEOPTS="-j3" VIDEO_CARDS="nouveau" INPUT_DEVICES="evdev" USE="X pdf jpeg" CHOST="x86_64-pc-linux-gnu" The complete build log is of course too large to post, but again is available in the folder linked here https://dolomit.geo.uni-bremen.de/owncloud/index.php/s/7kfsyL9faRQhCaI emerge.info is here emerge.info.txt build.log tail is here llvm.txt Thanks for any ideas any one can offer.

I'm curious if there is any current effort to track packages not building under Clang/LLVM. FreeBSD switched as a default, and I've heard that Debian was considering a switch at one point. Gentoo seemed to have an effort to track packages, but it seems like it may have fallen off the radar. There are some major blockers, like glibc, but the list already seems fairly small. Are there any formal plans for support Clang/LLVM as a system compiler going forward?
