[PATCH] D96838: Add GNU attribute 'retain'

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

GCC 11 hasn't been released yet, so can we still engage with GCC about the semantics of this attribute?  This is a very low-level attribute, and I don't understand why it was made separate instead of just having `used` add the appropriate section flag on targets that support it.
