Detailed Description

template<typename T, size_t ItemsGroupSize = 512>
class llvm::dwarf_linker::parallel::ArrayList< T, ItemsGroupSize >

This class is a simple list of T structures.

It keeps elements as pre-allocated groups to save memory for each element's next pointer. It allocates internal data using specified per-thread BumpPtrAllocator. Method add() can be called asynchronously.
