This compiler will be identified as `gcc_arm`. It is recommended to use version `12.2.Rel1`. Support for building with versions 11.2 and earlier of GCC (GNU Arm Embedded Toolchain / `arm-none-eabi-gcc`) was some removed in [#1043](https://github.com/ARMmbed/DAPLink/pull/1043) because of incompatibilities.
     * [Arm Compiler 6](https://developer.arm.com/tools-and-software/embedded/arm-compiler) . This compiler will be identified as `armclang`. Only supported on Linux and Windows.
