Methods

¶static Expected<
    std::unique_ptr<FDSimpleRemoteEPCTransport>>
Create(
    llvm::orc::SimpleRemoteEPCTransportClient& C,
    int InFD,
    int OutFD)

Description

Create a FDSimpleRemoteEPCTransport using the given FDs for reading (InFD) and writing (OutFD).

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:107

Parameters

llvm::orc::SimpleRemoteEPCTransportClient& C

int InFD

int OutFD

¶static Expected<
    std::unique_ptr<FDSimpleRemoteEPCTransport>>
Create(
    llvm::orc::SimpleRemoteEPCTransportClient& C,
    int FD)

Description

Create a FDSimpleRemoteEPCTransport using the given FD for both reading and writing.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:112

Parameters

llvm::orc::SimpleRemoteEPCTransportClient& C

int FD

¶FDSimpleRemoteEPCTransport(
    llvm::orc::SimpleRemoteEPCTransportClient& C,
    int InFD,
    int OutFD)

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:126

Parameters

llvm::orc::SimpleRemoteEPCTransportClient& C

int InFD

int OutFD

¶void disconnect()

Description

Trigger disconnection from the transport. The implementation should respond by calling handleDisconnect on the client once disconnection is complete. May be called more than once and from different threads.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:123

¶void listenLoop()

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:132

¶llvm::Error readBytes(char* Dst,
                      size_t Size,
                      bool* IsEOF = nullptr)

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:130

Parameters

char* Dst

size_t Size

bool* IsEOF = nullptr

¶llvm::Error sendMessage(
    llvm::orc::SimpleRemoteEPCOpcode OpC,
    uint64_t SeqNo,
    llvm::orc::ExecutorAddr TagAddr,
    ArrayRef<char> ArgBytes)

Description

Send a SimpleRemoteEPC message. This function may be called concurrently. Subclasses should implement locking if required for the underlying transport.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:120

Parameters

llvm::orc::SimpleRemoteEPCOpcode OpC

uint64_t SeqNo

llvm::orc::ExecutorAddr TagAddr

ArrayRef<char> ArgBytes

¶llvm::Error start()

Description

Called during setup of the client to indicate that the client is ready to receive messages. Transport objects should not access the client until this method is called.

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:118

¶int writeBytes(const char* Src, size_t Size)

Declared at: llvm/include/llvm/ExecutionEngine/Orc/Shared/SimpleRemoteEPCUtils.h:131

Parameters

const char* Src

size_t Size
