CC1310: TICLANG Compiler & Code Composer Studio (& CMake)

I am having some issues getting any CC1310 based example code to compile when using the CLang compiler (v3.2.1.LTS). My end goal is to build my code using CMake thanks to a recent addition by Alan Phipps at TI (CMake addition here). I am to the point that I am getting identical errors between CCS and CMake, but for now we can ignore the CMake portion.

When opening the `rfPacketRx` demo within CCS, I can initially compile without issue using the TI v20.2.7LTS compiler, however if I go to the project properties and update the compiler to use TI Clang v3.2.1.LTS I start getting error saying that parameter references within a `naked` function are not allowed. (I'm getting the same errors when invoking the build via CMake as well)

/home/stephen/ti/simplelink_cc13x0_sdk_4_20_02_07/source/ti/devices/cc13x0/driverlib/cpu.h:373:28: error: parameter references not allowed in naked functions
                    : "r" (ui32NewBasepri)
                           ^
/home/stephen/ti/simplelink_cc13x0_sdk_4_20_02_07/source/ti/devices/cc13x0/driverlib/cpu.h:366:38: note: attribute is here
__STATIC_INLINE void __attribute__ ((naked))

When digging into the files, it then becomes apparent that the `__TI_COMPILER_VERSION__` macro is not being defined or used.

    __asm("    msr     BASEPRI, r0\n");
}

    // Set the BASEPRI register.
    msr     BASEPRI, r0;
    bx      lr
}
#elif defined(__TI_COMPILER_VERSION__)
__STATIC_INLINE void
CPUbasepriSet(uint32_t ui32NewBasepri)
{
    // Set the BASEPRI register.
    __asm("    msr     BASEPRI, r0\n");
}
#else
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wattributes"
__STATIC_INLINE void __attribute__ ((naked))
CPUbasepriSet(uint32_t ui32NewBasepri)
{
    // Set the BASEPRI register.
    __asm volatile ("    msr     BASEPRI, %0\n"
                    "    bx      lr\n"
                    : /* No output */
                    : "r" (ui32NewBasepri)
                   );
}
#pragma GCC diagnostic pop
#endif

I can manually define the version macro myself (yikes) and I get a bit further but then there are compiler warnings about legacy pragmas being used in the example source which are not supported in ticlang. I'll solve that when I get to it, but I'd like to figure out why the compiler version isn't being set.

Any help is greatly appreciated. Thanks!
