Member Function Documentation

allocate()

void llvm::orc::EPCGenericJITLinkMemoryManager::allocate ( const jitlink::JITLinkDylib * JD, jitlink::LinkGraph & G, OnAllocatedFunction OnAllocated )

overridevirtual

Start the allocation process.

If the initial allocation is successful then the OnAllocated function will be called with a std::unique_ptr<InFlightAlloc> value. If the assocation is unsuccessful then the OnAllocated function will be called with an Error.

Implements llvm::jitlink::JITLinkMemoryManager.

static

Create an EPCGenericJITLinkMemoryManager using the given implementation symbol names.

These will be looked up in the given ExecutionSession's Bootstrap JITDylib.

deallocate()

void llvm::orc::EPCGenericJITLinkMemoryManager::deallocate ( std::vector< FinalizedAlloc > Allocs, OnDeallocatedFunction OnDeallocated )

overridevirtual

Deallocate a list of allocation objects.

Dealloc actions will be run in reverse order (from the end of the vector to the start).
