--- Comment #18 from Luke Geeson <luke.geeson at cs dot ucl.ac.uk> --- Indeed that is a plus - I have 167k concurrency tests that I feed through LLVM/GCC -O1/2/3/fast and for GCC -Og that test compilation from the C/C++ to PPC memory models. If you are interested I can provide them publicly (although I understand given the above that you may like to wait until I have ensured there are no more issues).
