Instances of this class represent a single low-level machine instruction.

Base class for classes that define behaviour that is specific to both the target and the object forma...

Generic base class for all target subtargets.

LLVM Value Representation.

This class implements an extremely fast bulk output stream that can only output to a stream.

This is an optimization pass for GlobalISel generic memory operations.
