Constructor & Destructor Documentation

◆ EPCGenericJITLinkMemoryManager()

llvm::orc::EPCGenericJITLinkMemoryManager::EPCGenericJITLinkMemoryManager	(	ExecutorProcessControl &	EPC,
		SymbolAddrs	SAs
	)

inline

Create an EPCGenericJITLinkMemoryManager instance from a given set of function addrs.

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.
