Nick Lewycky 3e63076980 Add 'umax' similar to 'smax' SCEV. Closes PR2003. ... Parse reversed smax and umax as smin and umin and express them with negative or binary-not SCEVs (which are really just subtract under the hood). Parse 'xor %x, -1' as (-1 - %x). Remove dead code (ConstantInt::get always returns a ConstantInt). Don't use getIntegerSCEV(-1, Ty). The first value is an int, then it gets passed into a uint64_t. Instead, create the -1 directly from ConstantInt::getAllOnesValue(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47360 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-20 06:48:22 +00:00
