Methods

¶EntryStage(llvm::mca::SourceMgr& SM)

Declared at: llvm/include/llvm/MCA/Stages/EntryStage.h:39

Parameters

llvm::mca::SourceMgr& SM

¶llvm::Error cycleEnd()

Description

Called once at the end of each cycle.

Declared at: llvm/include/llvm/MCA/Stages/EntryStage.h:45

¶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.

¶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/EntryStage.h:43

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/EntryStage.h:42

¶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/EntryStage.h:41

Parameters

const llvm::mca::InstRef& IR
