Member Variables

public const llvm::InstrInfoQuery IIQ

public bool CanUseUndef = true

Controls whether simplifications are allowed to constrain the range of possible values for uses of undef. If it is false, simplifications are not allowed to assume a particular value for a use of undef for example.
