I filed the following, and CC'ed you:

Which settings do you suggest? I ran:
  ~/llvm/sandbox/bin/lnt runtest nt --sandbox SANDBOX --cc
/home/user/llvm/install/bin/armv7-unknown-linux-gnueabihf-clang --cxx
/home/user/llvm/install/bin/armv7-unknown-linux-gnueabihf-clang++
--llvm-src ../llvm --llvm-obj ./ --test-suite ../test-suite -j2
--optimize-option=-O0

FWIW it looks like --small is broken on some tests.
