Benjamin Kramer f5b75932b8 While SimplifyDemandedBits constant folds this, we can't rely on it here. ... It's possible to craft an input that hits the recursion limits in a way that SimplifyDemandedBits doesn't simplify the icmp but ComputeMaskedBits can infer which bits are zero. No test case as it depends on too many other things. Fixes PR9609. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128777 91177308-0d34-0410-b5e6-96231b3b80d8		2011-04-02 18:50:58 +00:00
