...become available); also, we plan to eventually contribute everything to the clang trunk (initial patches have already been committed). This implementation supports 3.1 version of OpenMP standard in full; it passes all OpenMP tests we tried with it so far (this includes OpenMP Validation Suite from OpenUH Research Compiler, SPEC OMP2012 and internal Intel test suites). Performance-wise, it demonstrates similar gains and scalability as other compilers with OpenMP support. (Sorry, I can’t be more specific here, as properly reporting performance results is a precise and laborious process. You are welco...

Another potential solution would be to take the validation suite from the OpenUH compiler http://web.cs.uh.edu/~openuh/download/ (which is BSD licensed), and start to build a more comprehensive set of tests from that. Since it is BSD I believe we could take it without asking, however I'd like to get an ACK from the authors before doing that. The other issues to consider...

Now that we've kick-started the LLVM OpenMP runtime discussion, I want to make a concrete proposal to get a test suite up and running for the LLVM OpenMP runtime. I don't think the current setup as an LLVM subproject is sustainable going forward without some form of testing support, automated or otherwise. The motivation: It's difficult to make changes to the source without some
