[PATCH] D11740: ABI versioning macros for libc++

[Eric Fiselier via cfe-commits]

EricWF added a comment.

I don't think the tricky part of this patch is actually implementing the ABI macros. The tricky part is defining how libc++ should use the macros.  Some questions I would like to see answered:

1. How long is a major and minor ABI version supported?
2. When is the major and minor ABI version bumped?
3. How will maintaining multiple ABI versions affect code complexity and maintainability?

I would want to see documentation accompany this patch that anwsers some of these questions. It could we written in reStructured text after http://reviews.llvm.org/D12129 lands.
