shared::WrapperFunctionResult doJITDispatch(
    const void* FnTag,
    const char* ArgData,
    size_t ArgSize)

Declared at: llvm/include/llvm/ExecutionEngine/Orc/TargetProcess/SimpleRemoteEPCServer.h:152

Parameters

const void* FnTag
const char* ArgData
size_t ArgSize

uint64_t getNextSeqNo()

Declared at: llvm/include/llvm/ExecutionEngine/Orc/TargetProcess/SimpleRemoteEPCServer.h:159

void handleCallWrapper(
    uint64_t RemoteSeqNo,
    llvm::orc::ExecutorAddr TagAddr,
    llvm::orc::SimpleRemoteEPCArgBytesVector
        ArgBytes)

Declared at: llvm/include/llvm/ExecutionEngine/Orc/TargetProcess/SimpleRemoteEPCServer.h:148

Parameters

uint64_t RemoteSeqNo
llvm::orc::ExecutorAddr TagAddr
llvm::orc::SimpleRemoteEPCArgBytesVector ArgBytes

void handleDisconnect(llvm::Error Err)

Description

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).

Declared at: llvm/include/llvm/ExecutionEngine/Orc/TargetProcess/SimpleRemoteEPCServer.h:138

Parameters

llvm::Error Err

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

Description

Call to handle an incoming message. Returns 'Disconnect' if the message is a 'detach' message from the remote otherwise returns 'Continue'. If the server has moved to an error state, returns an error, which should be reported and treated as a 'Disconnect'.
