Hello,

I have 13.0-CURRENT and trying to build world for 13.1-releng
FreeBSD goodhost 13.0-CURRENT FreeBSD 13.0-CURRENT r339587 GENERIC  amd64


I've got following error in while buildword was compiling LLVM part:

Comment 2 Brooks Davis freebsd_committer freebsd_triage 2022-05-26 19:14:41 UTC 
This is quite an old CURRENT to upgrade from in one go (you have LLVM 6.0.1, but FreeVSD 13.0 shipped with 11.0.0 and even FreeBSD 11.4 has LLVM 10.0.0). I don't have any way to test 6.0.1 and there aren't going to be fixes for it. You may need to do this upgrade in multiple steps.

A few other thoughts:

clang just reporting "Killed" often means out of memory. Check dmesg or logs to see if that might have happened.

If you have a newer llvm installed by ports you may be able to use it with CROSS_TOOLCHAIN=llvm##, however if your ports are old enough you may need a to install one of the xtoolchain-llvm## ports (now obsolete) to make that work or do the equivalent by hand (see an example below):

/usr/local/share/toolchains/llvm13.mk:
XCC=/usr/local/bin/clang13
XCXX=/usr/local/bin/clang++13
XCPP=/usr/local/bin/clang-cpp13
XLD=/usr/local/bin/ld.lld13
CROSS_BINUTILS_PREFIX=/var/empty
X_COMPILER_TYPE=clang

^Triage: Closing as likely resource exhaustion.

@Alex Don't hesitate to re-open this issue with additional information if you are able to isolate/reproduce a specific bug in supported FreeBSD versions (including up to date CURRENT)
