◆ needsCleanup()

bool APValue::needsCleanup ( ) const

Returns whether the object performed allocations.

If APValues are constructed via placement new, needsCleanup() indicates whether the destructor must be called in order to correctly free all allocated memory.

◆ Profile()

void APValue::Profile ( llvm::FoldingSetNodeID & ID ) const

profile this value.

There is no guarantee that values of different types will not produce the same profiled value, so the type should typically also be profiled if it's not implied by the context.
