The following Clang compilers are supported:

Clang C/C++ Compiler v 3.9

Additional Notes

Only the x86_64 target has been tested. If the clang 3.9 compiler is built as a multi-target compiler, C++test code analysis may not function as expected on cross-compilation targets.
The pre-built cpptest runtime is not supported for dynamic analysis (unit testing and application monitoring). The runtime must be built during the execution of the test configuration by setting autoBuildDefault="true" in the test execution flow.
The xmm intrinsic headers are not supported for dynamic analysis.
Clang is used to link inside of C++test by default. If errors occur during linking that relate to missing C++ libraries, then change the linker in the Build Settings from clang to clang++.
The clang_3_9 compiler configuration does not use the default GCC for selecting headers. As a result, problems can occur during compilation of instrumented source code during unit testing and application monitoring.

C++test does not support C++17 features accepted by clang
Only the x86_64 target has been tested. If the clang 4.0 compiler is built as a multi-target compiler, C++test code analysis may not function as expected on cross-compilation targets.

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++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.

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.

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.

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.
