Create closure destructors with internal linkage #86013
Conversation
This makes these symbols visible in backtraces, at the cost of binary size. The long-term goal is to generate these functions with LinkOnceODRLinkage, using the contents of the HeapLayout to produce a mangled name, so they can be deduplicated across modules. rdar://149084103

We should do the same for partial apply forwarders too. Today they're generated once per |
Does that mean we should change those to have internal linkage in the short term as well? This PR is just meant as a short-term fix for rdar://149084103. I will be away until after Christmas. |

I think this comment is about the long term plan to deduplicate these functions. |
