[Piotr Padlewski via Phabricator via llvm-commits]

Prazek created this revision.
Prazek added reviewers: rsmith, sanjoy, amharc, kuhar.
Herald added a subscriber: hiraditya.

This feature is not needed, but it might be usefull in the future
to use metadata to mark what which function should support it
(and strip it when not).
