A better way of looking at it would be that most LLVM developers only
"pre-test" their
patches on their own development machines, which tend to be either x86-64 or x86
machines. While ARM is mostly similar, there are things that are done
differently at
both the LLVM and clang levels (eg, the Itanium C++ ABI used does some
things differently
to the x86 based ABIs.) In a way they're a lot more of a first line of
defence, trying to
ensure that all commits get at least superficial ARM testing
regardless of what platform
the developer is using.

It is a bit annoying that none of the available ARM boards suitable
for putting in a board
farm have quite the reliability level that would be ideal for buildbot use.
