llvm dev - Feb 2019 - debugging installation problem

Sorry in advance for the limited details.

I have a build of a recent (Monday) llvm/clang which I have installed in the
expected way in my environment but I am getting failures like this;

In file included from <some
directory>/lib/clang/stable/include/x86intrin.h:29:
In file included from <some
directory>/lib/clang/stable/include/immintrin.h:118:
<some directory>/lib/clang/stable/include/avx512cdintrin.h:37:20: error:
use of undeclared identifier '__builtin_ia32_vpconflictdi_512'
  return (__m512i) __builtin_ia32_vpconflictdi_512 ((__v8di) __A);
                   ^
<some directory>/lib/clang/stable/include/avx512cdintrin.h:59:20: error:
use of undeclared identifier '__builtin_ia32_vpconflictsi_512'
  return (__m512i) __builtin_ia32_vpconflictsi_512 ((__v16si) __A);
                   ^
Any suggestions on what might be messed up in the build/installation?
(In other contexts I would delete all build directories and restart but in this
workflow I know everything started from clean checkouts)

Thanks for any help
david

Your clang and your llvm don't match, they're often version locked and
you need to make sure both of them are the same-ish revision.

Given they in separate repos, is there a way to to verify which revisions go
together? Is it enough that the clang (shortly) after llvm in time?
