FreeBSD 11.2-STABLE #0 r344143
Maybe similar to 206179
References to emmintrin.h make both system and port builds to fail.

Can you add the output of:
% clang --version
% ls /usr/lib/clang/
emmintrin.h should be in /usr/lib/clang/<version>/include/emmintrin.h
Too late I'm afraid, in the middle of an update to my precious home workstation.
What I did after the failing builds
Made sure that I had not run make delete-old and delete-old-libs after the normal update steps - confirmed - it was done after a Feb 15 update.
I am positive I did not rm anything manually
Ran svnlite up /usr/src again
Tried make buildworld again - failed
Checked /usr/lib/clang/ - empty!
Did cp -Rp /usr/local/llvm<version>/lib/clang/ /usr/lib/clang
Then everything worked fine - I suppose we have to assume I *did* something, however, I cannot see what it was unfortunately. This bug can probably be closed unless someone else have similar problems.
There is a message on todays freebsd-stable from email@example.com exactly what I experienced.
Thank you for your time,

Thanks for the update.
This comes up every now and then so there must be come common set of steps/process that folks are following that leads to this case.
I have a system in this state doing an update from stable/12 to HEAD if you want to chase this to ground.
root@12:/usr/src # clang --version
FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM 6.0.1)
Thread model: posix
root@12:/usr/src # ls /usr/lib/clang/

Right, but the actual question is: how did it get into this state? After a normal installation, this directory should exist, and it should have the clang internal headers under (in this case) a subdirectory 6.0.1.
Is this when people install a system using WITHOUT_CLANG, and then copy a /usr/bin/clang executable by hand onto it, or something?
(In reply to Dimitry Andric from comment #6)
I ran into this before on a frankeninstall where I did a make install in usr.bin/clang but not lib/clang (i.e., I had some 11.x installation but tried installing just the new compiler from a stable/11 build).
In my case this system has an empty /etc/src-conf and /etc/make.conf with the exception of META_MODE and was following head until stable/12 branched, I followed stable/12 for a while and am now trying to get it to head again.

To your question, I suspect that while folks perform a tidy-up of their environment, you know like "cd /usr/src && make delete-old" they proceed with something like "find -anewer /usr/lib/ -delete;" which inadvertently blows away the /usr/lib/clang/$VER/include - ta dah, kaput!
I know, because its a curse being tidy! ;)
If this happens to you, here's a hint do NOT copy
because you'll duplicate things like stddef.h and the compile will fail. You might be able to get by with just copying *intrin.h, but I was impatient.
I know this is tedious but much better to either:
- read the Makefile to identify only what you need; or
It really threw me to find that the build required something outside either /usr/obj or /usr/src. Learning something new everyday... Hmm I wonder why
pkg-static isn't part of a buildworld, I do after all build from source; perhaps, for tomorrow ;)
