Legalize the Machine IR a function s Machine IR

This file defines the retire stage of a default instruction pipeline.

Subclass of Error for the sole purpose of identifying the success path in the type system.

Lightweight error class with error context and mandatory checking.

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

An InstRef contains both a SourceMgr index and Instruction pair.

SmallVectorImpl< WriteState > & getDefs()

An instruction propagated through the simulated instruction pipeline.

void notifyEvent(const EventT &Event) const

Notify listeners of a particular hardware event.

This is an optimization pass for GlobalISel generic memory operations.
