Thank you for sharing this, it is an excellent reference to have bookmarked. (Found it via Google.)

Xcode 5 final release is clang-500.2.76

Really?
This is no change from "500.2.75" where is my.

any chance you know what version of LIBC++ they are shipping with each one of these Apple LLVM versions?

I don't record the libc++.

After today's update of command line tools/xcode I get:

About Xcode:
Version 6.2 (6C131e)

/usr/bin/clang++ --version
Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.1.0
Thread model: posix

Thanks.

After today's update of command line tools/xcode I get:

About Xcode:

/usr/bin/clang++ --version
Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.1.0
Thread model: posix

(The bug preventing having debug symbols with C++ code containing C++14 type-deduced (auto) functions seems to be corrected. Hooray! :-))

EDIT: I see now that this update was already included in the list above. Sorry for the duplicate.

Xcode 7.0 beta (7A120f) after xcode-select'ing it:
Apple LLVM version 7.0.0 (clang-700.0.53)
Target: x86_64-apple-darwin14.4.0
Thread model: posix

Thanks @karies.
I update this page with your information.

Does anyone know how to change the compiler version on an xcode target? I can only select 'latest llvm' from the build settings.

Xcode 7,1 beta
Apple LLVM version 7.0.0 (clang-700.1.74)
Target: x86_64-apple-darwin14.4.0
Thread model: posix

Xcode 7.0 (7A220)
$ clang --version
Apple LLVM version 7.0.0 (clang-700.0.72)

Thanks @LogicalKnight.

Xcode 7.2 beta (7C46l)
Apple LLVM version 7.0.0 (clang-700.1.78)
Target: x86_64-apple-darwin15.0.0
Thread model: posix

Is Xcode 7's LLVM based on 3.7? I assume it is since they were both released around the same time, but I'm curious why clang --version no longer reports this.

Xcode 7.1.1 (7B1005)
Apple LLVM version 7.0.0 (clang-700.1.76)
Target: x86_64-apple-darwin14.5.0
Thread model: posix
(Same as Xcode 7.1)

Any ideas when Apple is going to release clang-700.0.72 sources?

Xcode Version 7.2 (7C68)
Apple LLVM version 7.0.2 (clang-700.1.81)

More detailed version of previous post:

Xcode Version 7.2 (7C68)
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin15.2.0
Thread model: posix

Xcode 7.3 beta 2 (7D129n)
Apple LLVM version 7.3.0 (clang-703.0.16.1)
Target: x86_64-apple-darwin15.3.0
Thread model: posix

@ikantor clang-700.0.72 is finally out - http://opensource.apple.com/release/developer-tools-70/

The reported Target is based on the OS being used and has little to do with the clang version. The thread model is hard-coded as 'posix'. Neither of these need to be recorded.

Xcode 7.3 (7D175)
Apple LLVM version 7.3.0 (clang-703.0.29)
Target: x86_64-apple-darwin15.4.0
Thread model: posix

What about versions of the vanilla LLVM/Clang for clang-7xx.x.xx versions?

Apple LLVM passes from 7.0 to 7.3??? why? there is no 7.1 nor 7.2?

Which version of LLVM is Apple LLVM 7.3 based on?

Apple LLVM 7.0 looks like based on LLVM 3.7.0svn (I'm guessing from http://opensource.apple.com/source/clang/clang-700.0.72/src/configure)

Xcode 7.3.1 (7D1014)
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.4.0
Thread model: posix

+1 for how can i know the vanilla clang version apple is using basis

Looking at the sources (src/CMakeLists.txt), it appears AppleClang is based on (approximately) the following LLVM branches:
clang-700.0.72 => LLVM 3.7.0
clang-700.1.76 => LLVM 3.7.0
clang-700.1.81 => LLVM 3.7.0
clang-703.0.29 => LLVM 3.8.0
clang-703.0.31 => LLVM 3.8.0

Xcode 8 beta
Apple LLVM version 8.0.0 (clang-800.0.31)
Target: x86_64-apple-darwin16.0.0
Thread model: posix

Xcode 8
Apple LLVM version 8.0.0 (clang-800.0.38)
Target: x86_64-apple-darwin15.6.0
Thread model: posix

Any idea the llvm version for clang-800.0.38?
