-# When building a software that depends on LLVM, utility llvm-config should be

-Subject: [PATCH] Ensure that variant part discriminator is read by
- MetadataLoader
-
-https://reviews.llvm.org/D42082 introduced variant parts to debug info
-in LLVM. Subsequent work on the Rust compiler has found a bug in that
-patch; namely, there is a path in MetadataLoader that fails to restore
-the discriminator.
-
-This patch fixes the bug.
