[PATCH] D100630: [Debug-Info][DBX] DW_TAG_rvalue_reference_type should not be generated when dwarf version is smaller than 4

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added a comment.

If gracefully lowering rvalue references to references needs knowledge about the Clang typesystem (or depends on LLVM IR type uniquing to be efficient, as @dblaikie points out) then we should do it in the Clang frontend. As much as we can we should avoid encoding debug info format specific knowledge in the Clang frontend, but that's not always possible. I'm fine with taking this patch.
