Hi @homerdin,

Great to see you taking the effort to make the test-suite more relevant!
I think it'd be helpful if you could also add a little explanation of how adding this code makes the test-suite more relevant.
I'm assuming that this kind of code is common in some domain (HPC?) and that there is no other benchmark already in the test-suite with similar enough properties?

With my experience so far on using the test-suite to track the performance evolution of LLVM, an execution time of about 1 second should be roughly what we aim for to have a good balance between not having too much noise in the execution time vs the benchmark producing results quickly. I'm just wondering roughly what the characteristics of your machine is?

Other than that, I just think that you'll also need to add this new directory as an exception near the end of top-level LICENSE.TXT file.
