I'd be OK with that. Did the tests pass for you if you raise the limit?

Yes, re-running "gmake check-all" from the
rc2/Phase3/Release/llvmCore-3.6.0-rc2.obj subdirectory succeeds now:

                      -- Testing: 20187 tests, 4 threads --
Testing Time: 250.10s
  Expected Passes    : 19873
  Expected Failures  : 101
  Unsupported Tests  : 213

The hypervisor I'm running on is also much less busy, which is why the
testing time is now just 250 seconds... Virtualization is not always that great
:)

I've also uploaded the resulting binaries to the sftp area:

SHA256 (clang+llvm-3.6.0-rc2-i386-unknown-freebsd10.tar.xz) =
820a4bb750872ae4055cc9bc5305f7e1ef9e77e192812521ee5adfc0d2049461
SHA256 (clang+llvm-3.6.0-rc2-amd64-unknown-freebsd10.tar.xz) =
c6e59552a9c3ca3486d803438594467d7b0f740e36170fc597eec5e0d1a42859

Do you want to send a patch out to the list for raising the timeout?

Thanks,
