I read the documentation and it says "Arm Compiler for Embedded FuSa is built on LLVM technology and preserves the functionality of that technology where possible".
There is no cross reference between the versions. Is there a way to find out Which version of LLVM clang is Arm Compiler for Embedded FuSa 6.16LTS is build from?
The macro __VERSION__ is defined as:
#define __VERSION__ "Clang 13.0.0"
