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
