A.6 Clang and LLVM documentation
ARM® Compiler is based on Clang and LLVM compiler technology.
The ARM Compiler documentation describes features that are specific to, and supported by, ARM Compiler. Any features specific to ARM Compiler that are not documented are not supported and are used at your own risk. Although open-source Clang features are available, they are not supported by ARM and are used at your own risk. You are responsible for making sure that any generated code using unsupported features is operating correctly.
