Chandler, is this reasonable?</div></blockquote></div><br class="">My inclination would be to follow the testing structure of vector-shuffle-512-v8.ll and extend it. Those aren't generated by my fuzzer directly. I have a number of scripts that help generate these style of test cases some I have mailed out (shufle_test_gen.py) but never really got consensus on submitting (its terrible python code I'm afraid). I also have a script that takes an existing test of the form of these shuffle tests and re-computes the file-check portions. I can mail that out if I haven't already.</div></div>
