[PATCH] D42082: Add DWARF for discriminated unions

[Tom Tromey via Phabricator via llvm-commits]

tromey added a comment.

Another thing to consider is that this is really just the first patch in a larger project.  There are other things in Rust that will require new debuginfo.  Some of these can be mapped to existing DWARF (e.g., traits can probably use `DW_TAG_interface` pretty comfortably); but some cannot (e.g., the distinction between tuples and structs).
