[PATCH] D71219: Fix conflict value for metadata "Objective-C Garbage Collection" in the mix of swift and Objective-C bitcode

[Steven Wu via Phabricator via llvm-commits]

steven_wu added a comment.

Breaking part the meta data sounds like a good idea. You will probably need to combine the value in the backend to generate the field in the object file.

Also, please add test case. If you go down the route of splitting the value, you need:

- codegen tests for correct value in the object file
- llvm-link tests for combining objc and swift bitcode
- auto upgrade test if you want to support the old bitcode
