Public Member Functions
InstrumentManager (const MCSubtargetInfo &STI, const MCInstrInfo &MCII, bool EnableInstruments=true)
virtual ~InstrumentManager ()=default
virtual bool shouldIgnoreInstruments () const
Returns true if llvm-mca should ignore instruments.
virtual bool supportsInstrumentType (StringRef Type) const
virtual UniqueInstrument createInstrument (StringRef Desc, StringRef Data)
Allocate an Instrument, and return a unique pointer to it.
virtual SmallVector< UniqueInstrument > createInstruments (const MCInst &Inst)
Return a list of unique pointers to Instruments, where each Instrument is allocated by this function.
virtual unsigned getSchedClassID (const MCInstrInfo &MCII, const MCInst &MCI, const SmallVector< Instrument * > &IVec) const
Given an MCInst and a vector of Instrument, a target can return a SchedClassID.
virtual bool canCustomize (const ArrayRef< Instrument * > IVec) const
virtual void customize (const ArrayRef< Instrument * > IVec, llvm::mca::InstrDesc &Desc) const

This class allows targets to optionally customize the logic that resolves scheduling class IDs.

Targets can use information encoded in Instrument objects to make more informed scheduling decisions.

◆ getSchedClassID()

Given an MCInst and a vector of Instrument, a target can return a SchedClassID.

This can be used by a subtarget to return a PseudoInstruction SchedClassID instead of the one that belongs to the BaseInstruction This can be useful when a BaseInstruction does not convey the correct scheduling information without additional data. By default, it returns the SchedClassID that belongs to MCI.

Reimplemented in llvm::mca::RISCVInstrumentManager.
