Chris Lattner 4de2c76542 Fix m_Not and m_Neg to not match random ConstantInt's. Before ... these would try hard to match constants by inverting the bits and recursively matching. There are two problems with this: 1) some patterns would match when we didn't want them to (theoretical) 2) this is insanely expensive to do, and most often pointless. This was apparently useful in just 2 instcombine cases, which I added code to handle explicitly. This change speeds up 'opt' time on 176.gcc by 1% and produces bitwise identical code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123518 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-15 05:52:27 +00:00
