Detailed Description

template<typename T, unsigned N, typename C = std::less<T>>
class llvm::SmallSet< T, N, C >

SmallSet - This maintains a set of unique values, optimizing for the case when the set is small (less than N).

In this case, the set can be maintained with no mallocs. If the set gets large, we expand to using an std::set to maintain reasonable lookup times.

◆ insert() [1/3]

insert - Insert an element into the set if it isn't already there.

Returns a pair. The first value of it is an iterator to the inserted element or the existing element in the set. The second value is true if the element is inserted (it was not in the set before).
