Note that this PR does not exhaustively port the logic in [clang]. Only the obviously correct portion and what is necessary to fix a regression from LLVM 12 that relates to `-Crelocation_model=static`. Fixes #83335 [clang]: https://github.com/llvm/llvm-project/blob/3001d080c813da20b329303bf8f45451480e5905/clang/lib/CodeGen/CodeGenModule.cpp#L945-L1039 2020-08-30T15:45:07+00:00 mark markm@cs.wisc.edu 2020-08-28T03:58:48+00:00 urn:sha1:9e5f7d5631b8f4009ac1c693e585d4b7108d4275
