Ah OK.

Can you try running some of the failing lines manually and see if they
still fail?

Also are you doing these tests on LLVM 2.8, or trunk?

There's one caveat with running tests though:
if you have opt, llc, etc. in your path then 'make check' might use
those instead of the ones you just built.
IIRC I've bumped into that when I had an old LLVM 2.6 in /usr/local, and
2.7 tests failed.

make -j is fine, I do it all the time. I've never run make check
in parallel though.

Try 4.3 if SLES has it.
