Detailed Description
template<typename LeafTy>
class llvm::UnivariateLinearPolyBase< LeafTy >
UnivariateLinearPolyBase is a base class for ElementCount and TypeSize.
Like LinearPolyBase it tries to represent a linear polynomial where only one dimension can be set at any time, e.g. 0 * scale0 + 0 * scale1 + ... + cJ * scaleJ + ... + 0 * scaleK The dimension that is set is the univariate dimension.
