Chandler Carruth 6bb093bbe7 [x86] Rewrite a core part of the new vector shuffle lowering to handle one pesky test case correctly. This test case caused the old code to infloop occilating between solving the low-half and the high-half. The 'side balancing' part of single-input v8 shuffle lowering didn't handle the one pattern which can cause it to occilate. Fortunately the fuzz testing found this case. Unfortuately it was terrible to handle. I'm really sorry for the amount and density of the code here, I'd love suggestions on how to simplify it. I feel like there must be a simpler form here, but after a lot of days I've not found it. This is the only one I've found that even works. I've added the one pesky test case along with some nice comments explaining the core problem that we have to solve here. So far this has survived approximately 32k test cases. More strenuous fuzzing commencing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215519 91177308-0d34-0410-b5e6-96231b3b80d8		2014-08-13 01:25:45 +00:00
