I find the naming conventions for the matchers kind of weird, but I see that they're meant to be familiar to users of the IR level matcher APIs so I suppose they at least make sense. Let's get this in and start using it.


IIRC someone was saying they wanted to use this outside of GISel as well. Should this be hoisted up into CodeGen rather than being part of GISel?


Remove these comments. It'll be obvious what's missing as people start using these APIs, and people can just add things as needed.

Yes - I think Hal mentioned that. However, there is only GISel matchers right now, and I figured (also due to the GISel Utils include in this file), we can move the file later when there's a use case for it.


Good point. Will remove.

Committed in r323400.
Thanks for the review.

Does this need to be static inline?
