[PATCH] D27721: Add a c_str() member to StringLiteral

[Zachary Turner via Phabricator via llvm-commits]

zturner added a comment.

Probably should take this discussion to a thread specifically about `StringRefZ`, but fwiw I think that would complicate the logic of `StringRef` considerably while also introducing thread synchronization issues and potentially increasing the size of a `StringRef`.  It's possible seeing the actual implementation would change my mind, but so far it doesn't sound like a good candidate for `StringRef`.

Back to this patch, anyone have any other thoughts?  FWIW I changed my usage so I'm now storing a `StringRef` instead of a `StringLiteral` (because it actually needed to be constructed without a literal in some scenarios), but the API still seems to make sense here to me (and the attribute seems like a good addition regardless)
