Sanjay Patel efd8885772 [InstSimplify] fold negation of sign-bit ... 0 - X --> X, if X is 0 or the minimum signed value 0 - X --> 0, if X is 0 or the minimum signed value and the sub is NSW I noticed this pattern might be created in the backend after the change from D25485, so we'll want to add a similar fold for the DAG. The use of computeKnownBits in InstSimplify may be something to investigate if the compile time of InstSimplify is noticeable. We could replace computeKnownBits with specific pattern matchers or limit the recursion. Differential Revision: https://reviews.llvm.org/D25785 llvm-svn: 284649		2016-10-19 21:23:45 +00:00
