void llvm::AMDGPU::SendMsg::decodeMsg ( unsigned  Val,
uint16_t MsgId,
uint16_t OpId,
uint16_t StreamId,
const MCSubtargetInfo STI 
)

◆ encodeMsg()

LLVM_READNONE uint64_t llvm::AMDGPU::SendMsg::encodeMsg ( uint64_t  MsgId,
uint64_t  OpId,
uint64_t  StreamId 
)

Definition at line 1962 of file AMDGPUBaseInfo.cpp.

References OP_SHIFT_, and STREAM_ID_SHIFT_.

◆ getMsgId()

int64_t llvm::AMDGPU::SendMsg::getMsgId ( StringRef  Name,
const MCSubtargetInfo STI 
)

Map from a symbolic name for a msg_id to the message portion of the immediate encoding.

A negative return value indicates that the Name was unknown or unsupported on this target.
