Public Member Functions
	MicroOpQueueStage (unsigned Size, unsigned IPC=0, bool ZeroLatencyStage=true)
bool	isAvailable (const InstRef &IR) const override
	Returns true if it can execute IR during this cycle.
bool	hasWorkToComplete () const override
	Returns true if some instructions are still executing this stage.
Error	execute (InstRef &IR) override
	The primary action that this stage performs on instruction IR.
Error	cycleStart () override
	Called once at the start of each cycle.
Error	cycleEnd () override
	Called once at the end of each cycle.

◆ cycleEnd()

Error llvm::mca::MicroOpQueueStage::cycleEnd ( )	overridevirtual

Error llvm::mca::MicroOpQueueStage::cycleStart ( )	overridevirtual

Called once at the start of each cycle.

This can be used as a setup phase to prepare for the executions during the cycle.

Reimplemented from llvm::mca::Stage.
