Chandler Carruth adc58a657b [shuffle] Stand back! I'm about to (try to) do math! ... Especially with blends and large tree heights there was a problem with the fuzzer where it would end up with enough undef shuffle elements in enough parts of the tree that in a birthday-attack kind of way we ended up regularly having large numbers of undef elements in the result. I was seeing reasonably frequent cases of *all* results being undef which prevents us from doing any correctness checking at all. While having undef lanes is important, this was too much. So I've tried to apply some math to the probabilities of having an undef lane and balance them against the tree height. Please be gentle, I'm really terrible at math. I probably made a bunch of amateur mistakes here. Fixes, etc. are quite welcome. =D At least in running it some, it seems to be producing more interesting (for correctness testing) results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215540 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-13 12:27:18 +00:00
