The following Clang compilers are supported:

Clang C/C++ Compiler v 6.0

The avx2 intrinsic headers are not supported.
The avx512 intrinsic headers are not supported
This version has been tested with GCC 6 and newer. Pairing this compiler with older versions of GCC is unsupported.

Clang C/C++ Compiler v 8.0 (x86_64)

C++20 features are not supported.
Clang is a multitarget compiler. This configuration only supports the x86_64 architecture and is not suitable for any other target.
This version has been tested with the clang target x86_64-linux-gnu and the clang libc++ standard library.

This version has been tested with the clang target x86_64-linux-gnu and the clang libc++ standard library.

The following compiler configuration is now deprecated:

By default, clang is used to link inside of C++test. If errors occur during linking that relate to missing c++ libraries, then change the linker in the build settings from clang to clang++.
Only the x86_64 target has been tested. If the clang 5.0 compiler is built as a multi-target compiler, C/C++test code analysis may not function as expected on cross-compilation targets.
C++17 is not currently supported.
The avx512 intrinsic headers are not supported
This version has been tested with GCC 6 and newer. Pairing this compiler with older versions of GCC is unsupported.

Extended: Support has been validated with extended testing and is approved for use in safety-critical software development.
Standard: Support has been validated with standard testing and is approved for use in non-safety critical software development.
