failures in test-suite for make TEST=simple

I'm getting three failures.

TEST-FAIL: exec /home/rkotler/llvmpb3/build/projects/test-suite/SingleSource/UnitTests/Vector/SSE/sse.expandfft

I forgot to mention that you can also run "make TEST=simple report" which will generate a nice report.

Do you know why these tests fail ? You can step into the test directory and run 'make TEST=simple' from there. It will save you some time.

The first one failed on a diff:
******************** TEST (simple) 'sse.expandfft' FAILED!

when I create the report, there are no failures in it. so maybe these are being filtered for known failures.

I use the 'make TEST=simple' as a pre-commit test. I think that everybody should run these tests before committing to LLVM.

Is "simple" pretty comprehensive?

What is the largest test I can run from linux ?
