If you don't want to submit the results to an LNT server you can also just run the test-suite directly without going through LNT.

You should be able to do something like:
cmake -DCMAKE_C_COMPILER=/path/to/my/clang -DTEST_SUITE_SPECXXX_ROOT -DTEST_SUITE_SUBDIRS=External/SPECXXX -GNinja /path/to/test-suite
# NOte: use ccmake or cmake -L to see a list of variables you can tweak.

to build and run SPEC via the test-suite infrastructure.

I experimented a bit and cannot get it to work right.  However, it isn't really documented anywhere so maybe I didn't set it up properly.  Plus there's all the mention of llvmgcc...
