[PATCH] D117965: [AlwaysInliner] Enable call site inlining to make flatten attribute working again (PR53360)

[Arthur Eubanks via Phabricator via cfe-commits]

aeubanks added a comment.

The existing implementation only inlines top level call sites, which doesn't match gcc where all calls are recursively inlined [1]. gcc's implementation makes more sense IMO, only inlining top level call sites doesn't seem super useful.

I'd vote for properly implementing [1] or removing our support for flatten.
