Methods

¶DispatchStage(
    const llvm::MCSubtargetInfo& Subtarget,
    const llvm::MCRegisterInfo& MRI,
    unsigned int MaxDispatchWidth,
    llvm::mca::RetireControlUnit& R,
    llvm::mca::RegisterFile& F)

Declared at: llvm/include/llvm/MCA/Stages/DispatchStage.h:69

Parameters

const llvm::MCSubtargetInfo& Subtarget

const llvm::MCRegisterInfo& MRI

unsigned int MaxDispatchWidth

llvm::mca::RetireControlUnit& R

llvm::mca::RegisterFile& F

¶llvm::Error cycleStart()

Description

Called once at the start of each cycle. This can be used as a setup phase to prepare for the executions during the cycle.

Declared at: llvm/include/llvm/MCA/Stages/DispatchStage.h:78

¶void dump() const

Declared at: llvm/include/llvm/MCA/Stages/DispatchStage.h:82

¶llvm::Error execute(llvm::mca::InstRef& IR)

Description

The primary action that this stage performs on instruction IR.

Declared at: llvm/include/llvm/MCA/Stages/DispatchStage.h:79

Parameters

llvm::mca::InstRef& IR

¶bool hasWorkToComplete() const

Description

Returns true if some instructions are still executing this stage.

Declared at: llvm/include/llvm/MCA/Stages/DispatchStage.h:77

¶bool isAvailable(
    const llvm::mca::InstRef& IR) const

Description

Returns true if it can execute IR during this cycle.

Declared at: llvm/include/llvm/MCA/Stages/DispatchStage.h:73

Parameters

const llvm::mca::InstRef& IR
