Detailed Description

template<typename AllocatorTy>
class llvm::parallel::PerThreadAllocator< AllocatorTy >

PerThreadAllocator wraps a thread-unsafe allocator (e.g.

BumpPtrAllocator) for lock-free concurrent allocation: each thread receives its own sub-allocator on first allocation, and the PerThreadAllocator owns all sub-allocators. Recommended to used with the thread pool in Parallel.h even if there is no dependency on it.
