-Subject: [PATCH] Fix issue 57762
-
-Issue 57762 points out a compiler crash when the compiler was built
-using a stock LLVM 7.  LLVM 7 was released without a necessary fix for
-a bug in the DWARF discriminant code.
-
-This patch changes rustc to use the fallback mode on (non-Rust) LLVM 7.

-Closes #57762
