On Mac OS, if I run clang --version, I get:
Apple LLVM version 6.0 (clang-600.0.34.4) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.0.0
Thread model: posix
Since LLVM official page suggests that the current LLVM version is 3.5, it seems that Apple clang versioning is distinct from the open-source LLVM. The output (based on LLVM 3.5svn) suggests that probably it is 3.5 on my machine as well.
Now I got here since I wanted to compile a C++14 file, using g++ -std=c++14 main.cc. This page suggests that this option should work on clang 3.5. However, it works only with -std=c++1y, which works on clang 3.4 or earlier.
So what is LLVM open-source version equivalent for Apple's version? It seems 3.5 but then why it doesn't work so?

The tests are located in two separate repositories. The unit and regression tests are in the main “llvm”/ directory under the directories llvm/unittests and llvm/test (so you get these tests for free with the main LLVM tree). Use make check-all to run the unit and regression tests after building LLVM.
Open a terminal window. Enter the command (clang — version) to confirm if the Clang Compilers had already been installed.
Enter the command clang --version to see if the Clang compilers are already installed.
LLVM is a set of compiler and toolchain technologies that can be used to develop a front end for any programming language and a back end for any instruction set architecture.
It is some Version of the llvm 3.5 svn branch before the official 3.5 release version.
Meaning that it probably should have all features of 3.4 plus some of the 3.5 features.
