◆ DeinitializeProxy

using llvm::orc::EPCGenericJITLinkMemoryManager::DeinitializeProxy = Proxy<Error(ExecutorAddr, ArrayRef<ExecutorAddr>)>

Deinitialize the allocations with the given base addresses (running their deallocation actions) without releasing their memory.

Definition at line 47 of file EPCGenericJITLinkMemoryManager.h.

◆ InitializeProxy

using llvm::orc::EPCGenericJITLinkMemoryManager::InitializeProxy

Initial value:

Proxy<Expected<ExecutorAddr>(ExecutorAddr, tpctypes::FinalizeRequest)>

llvm::orc::ExecutorAddr

Represents an address in the executor process.

Definition ExecutorAddress.h:34

llvm::orc::Proxy

Definition Proxy.h:51

llvm::orc::tpctypes::FinalizeRequest

Definition TargetProcessControlTypes.h:56

Apply a finalize request; returns a key for the initialized allocation.

Definition at line 42 of file EPCGenericJITLinkMemoryManager.h.

◆ ReleaseProxy

using llvm::orc::EPCGenericJITLinkMemoryManager::ReleaseProxy = Proxy<Error(ExecutorAddr, ArrayRef<ExecutorAddr>)>

Release the allocations with the given base addresses.

Definition at line 50 of file EPCGenericJITLinkMemoryManager.h.

◆ ReserveProxy

using llvm::orc::EPCGenericJITLinkMemoryManager::ReserveProxy = Proxy<Expected<ExecutorAddr>(ExecutorAddr, uint64_t)>

Reserve an address range of the given size; returns its base.

Constructor & Destructor Documentation

◆ EPCGenericJITLinkMemoryManager()

llvm::orc::EPCGenericJITLinkMemoryManager::EPCGenericJITLinkMemoryManager	(	ExecutionSession &	ES,
		Bindings	B )

inline

Create an EPCGenericJITLinkMemoryManager instance from a given set of memory-manager bindings.

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.
