Chris Lattner bf5d8a8270 Three changes: ... 1. Teach GetConstantInType to handle boolean constants. 2. Teach instcombine to fold (compare X, CST) when X has known 0/1 bits. Testcase here: set.ll:test22 3. Improve the "(X >> c1) & C2 == 0" folding code to allow a noop cast between the shift and and. More aggressive bitfolding for other reasons was turning signed shr's into unsigned shr's, leaving the noop cast in the way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26131 91177308-0d34-0410-b5e6-96231b3b80d8		2006-02-12 02:07:56 +00:00
