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.

◆ 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).
