[PATCH] D116817: [IRBuilder] Simplify 'or 0, RHS' -> RHS on creation.

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

IRBuilder accepts a Folder that currently gives you the choice between no folding, target-independent constant folding and target-dependent constant folding. If we change the API to not be restricted to Constants, we could add a SimplifyFolder that calls into InstSimplify instead.

Maybe that would help more generally for what you're currently doing? We could generate code in the straightforward way, but let IRBuilder fold away trivial identities via simplification, without having to reimplement them.
