[cfe-dev] Forwards/backwards compatibility of libc++ on Mac OS X

[Dallman, John]

I have Xcode 4.1 with Clang 2.1 on Mac OS X 10.7, and Xcode 4.4 with Clang 4.0 on
Mac OS X 10.8. Both OSes have a /usr/lib/libc++.1.dylib run-time provided.

Are those run-times compatible? In particular, is building C++ with Clang 4.0 on
10.8 and running the resulting program on 10.7 with that older libc++.1.dylib
supported?

The filenames tend to indicate this, but I'd like to be sure it's supposed to
work before I start basing plans on that.

thanks,
