[PATCH] D126694: [C++20][Modules] Implementation of GMF decl elision.

[Chuanqi Xu via Phabricator via cfe-commits]

ChuanqiXu added a comment.

I haven't looked into the details. But I feel the feature worth a sentence in ReleaseNotes. (Maybe in the potential-breaking-change section). Also I think it'll be better to have an option `-fenable-discarding-unreachable-decls-in-gmf` to control the behavior. It'll be helpful for debugging if we missed some point.
