Called once at the end of each cycle.
Reimplemented in llvm::mca::EntryStage.
◆ cycleStart()

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 in llvm::mca::DispatchStage, llvm::mca::ExecuteStage, llvm::mca::EntryStage, and llvm::mca::RetireStage.
◆ execute()
The primary action that this stage performs on instruction IR.
Implemented in llvm::mca::DispatchStage, llvm::mca::ExecuteStage, llvm::mca::EntryStage, llvm::mca::InstructionTables, and llvm::mca::RetireStage.

Returns true if some instructions are still executing this stage.
Implemented in llvm::mca::DispatchStage, llvm::mca::ExecuteStage, llvm::mca::EntryStage, llvm::mca::InstructionTables, and llvm::mca::RetireStage.

◆ isAvailable()
Returns true if it can execute IR during this cycle.
