[llvm-dev] [RFC] Error handling in LLVM libraries.

[Lang Hames via llvm-dev]

Hi All,

An updated version of this proposal has been committed as r263609. Thanks
very much for all the discussion and feedback.

Once the dust has settled and any issues that survived pre-commit review
are cleared up I'll start writing a more thorough usage document.

Cheers,
Lang.
