Methods

¶ExecuteStage(llvm::mca::Scheduler& S)

Declared at: llvm/include/llvm/MCA/Stages/ExecuteStage.h:50

Parameters

llvm::mca::Scheduler& S

¶ExecuteStage(llvm::mca::Scheduler& S,
             bool ShouldPerformBottleneckAnalysis)

Declared at: llvm/include/llvm/MCA/Stages/ExecuteStage.h:51

Parameters

llvm::mca::Scheduler& S

¶llvm::Error cycleEnd()

Description

Called once at the end of each cycle.

Declared at: llvm/include/llvm/MCA/Stages/ExecuteStage.h:72

¶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/ExecuteStage.h:71

¶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/ExecuteStage.h:73

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/ExecuteStage.h:61

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

Description

Returns true if it can execute IR during this cycle.
