Detailed Description

template<typename T>
struct llvm::CalculateSmallVectorDefaultInlinedElements< T >

Helper class for calculating the default number of inline elements for SmallVector<T>.

This should be migrated to a constexpr function when our minimum compiler support is enough for multi-statement constexpr functions.
