OpenMPI Users - Is Anyone Using openmpi-clang33 or openmpi-clang34?

[Ken Cunningham]

There is one issue with that.

qt5-qtcreator needs clang-10 on arm for it’s libraries (that is actually the only reason why I initially fixed clang-10 to work on arm64 in the first place).

qt5-qtcreator cannot (could not) use any newer clang when I checked six months ago.

So — we still need clang-10 on arm64 even if we don’t use it as a compiler there.

I just noticed the buildbots building the clang-9.0 version for arm, but its worth noting that clang 9.0 and 10 are not reliable for arm, I have seen them generate bad code, fail with ICEs, so really there is little point in providing all but the clang11(and newer) version which is the first version with reliable arm support.
