Get Apple clang version and corresponding upstream LLVM version

Question

I want to understand which version of clang Apple installed in my macbook, to see with c++11 and/or c++14 features are available. I typed this command:

clang --version  //----response Apple LLVM version 7.0.0 (clang-700.1.76)      Target: x86_64-apple-darwin15.0.0     Thread model: posix 

But I am not able to understand what (clang-700.1.76) mean. How can I convert this code to a clang version?

This is the site where you could check c++ features available in clang version http://clang.llvm.org/cxx_status.html

Answer 1

Wikipedia's Xcode page has a map of Apple to LLVM versions. The LLVM column has the open-source LLVM/Clang version. From this you can look up a language feature in cppreference's chart of compiler support for language features.

Answer 2

Here is the best listing I've found that correlates Apple's clang versions with the LLVM versions:

https://trac.macports.org/wiki/XcodeVersionInfo

Previous versions used to say what LLVM version they corresponded to, but starting with 7.0, Apple decided to no longer do that. They even define the __clang_version__ and related preprocessor macros to indicate the Apple version number, not the LLVM version. So they're useless for this as well.

Unfortunately, it looks like the only way to see if you have a feature is to try it and check if it works. e.g. 7.0.2 still doesn't have OpenMP enabled by default (although it's enable-able), so I guess it's still 3.6, not 3.7 yet.
