◆ callWrapperAsync()

void llvm::orc::SimpleRemoteEPC::callWrapperAsync	(	ExecutorAddr	WrapperFnAddr,
		IncomingWFRHandler	OnComplete,
		ArrayRef< char >	ArgBuffer
	)

overridevirtual

Run a wrapper function in the executor.

The given WFRHandler will be called on the result when it is returned.

The wrapper function should be callable as:

CWrapperFunctionResult fn(uint8_t *Data, uint64_t Size);

inlinestatic

Create a SimpleRemoteEPC using the given transport type and args.

References llvm::orc::ExecutorProcessControl::D, and llvm::joinErrors().

◆ disconnect()

Error llvm::orc::SimpleRemoteEPC::disconnect ( )

overridevirtual

Disconnect from the target process.

This should be called after the JIT session is shut down.

Implements llvm::orc::ExecutorProcessControl.

Definition at line 110 of file SimpleRemoteEPC.cpp.

References llvm::orc::ExecutorProcessControl::D.

◆ handleDisconnect()

void llvm::orc::SimpleRemoteEPC::handleDisconnect ( Error Err )

overridevirtual

Handle a disconnection from the underlying transport.

No further messages should be sent to handleMessage after this is called. Err may contain an Error value indicating unexpected disconnection. This allows clients to log such errors, but no attempt should be made at recovery (which should be handled inside the transport class, if it is supported at all).

Implements llvm::orc::SimpleRemoteEPCTransportClient.

Definition at line 176 of file SimpleRemoteEPC.cpp.

References llvm::orc::shared::WrapperFunctionResult::createOutOfBandError(), llvm::dbgs(), llvm::joinErrors(), LLVM_DEBUG, and std::swap().

◆ handleMessage()

Expected< SimpleRemoteEPCTransportClient::HandleMessageAction > llvm::orc::SimpleRemoteEPC::handleMessage	(	SimpleRemoteEPCOpcode	OpC,
		uint64_t	SeqNo,
		ExecutorAddr	TagAddr,
		SimpleRemoteEPCArgBytesVector	ArgBytes
	)

overridevirtual

Handle receipt of a message.

Returns an Error if the message cannot be handled, 'EndSession' if the client will not accept any further messages, and 'ContinueSession' otherwise.

Implements llvm::orc::SimpleRemoteEPCTransportClient.

Definition at line 119 of file SimpleRemoteEPC.cpp.

◆ loadDylib()

Expected< tpctypes::DylibHandle > llvm::orc::SimpleRemoteEPC::loadDylib ( const char * DylibPath )

overridevirtual

Load the dynamic library at the given path and return a handle to it.

If LibraryPath is null this function will return the global handle for the target process.

Implements llvm::orc::ExecutorProcessControl.

Definition at line 28 of file SimpleRemoteEPC.cpp.

◆ lookupSymbols()

Expected< std::vector< tpctypes::LookupResult > > llvm::orc::SimpleRemoteEPC::lookupSymbols ( ArrayRef< LookupRequest > Request )

overridevirtual

Search for symbols in the target process.

The result of the lookup is a 2-dimentional array of target addresses that correspond to the lookup order. If a required symbol is not found then this method will return an error. If a weakly referenced symbol is not found then it be assigned a '0' value.

Implements llvm::orc::ExecutorProcessControl.

Run function with a int (*)(void) signature.
