[llvm-dev] Is the CppBackend still supported?

[Stanislav Manilov via llvm-dev]

[-- I was, in fact, looking for a way to generate a global constant
representing a string literal, and that's when (even the broken) CppBackend
came in handy. I don't think the IRBuilder can be used, but perhaps I'm
wrong. --] While writing this, I checked, and there are CreateGlobalString
and CreateGlobalStringPtr in IRBuilder, which seems to be what I needed.

Case in point. CppBackend taught me the wrong way to use the API.
