Detailed Description

This file provides utility for Memory Model Relaxation Annotations (MMRAs).

Those annotations are represented using Metadata. The MMRATagSet class offers a simple API to parse the metadata and perform common operations on it. The MMRAMetadata class is a simple tuple of MDNode that provides easy access to all MMRA annotations on an instruction.
