Detailed Description

Class which can be overriden by targets to modify the mca::Instruction objects before the pipeline starts.

A common usage of this class is to add immediate operands to certain instructions or to remove Defs/Uses from an instruction where the schedulinng model is incorrect.

This method can be overriden by targets to modify the mca::Instruction object after it has been lowered from the MCInst.

This is generally a less disruptive alternative to modifying the scheduling model.

Reimplemented in llvm::mca::AMDGPUInstrPostProcess, and llvm::mca::X86InstrPostProcess.
