@petertorelli Thanks for the question.
The difference compared to DSP is that DSP officially supports building on host. NN doesn't and we don't have plans to do that in the near future. But, I understand how this can be an issue. So, narrowing down the issue to progress.
If building for say x86, one shouldn't have to support Arm Cortex-M processor specific intrinsics at all. This can be made sure by not defining ARM_MATH_DSP or ARM_MATH_MVEI. Doing so will ensure only pure C code is used with some exceptions like __CLZ without any loss in functionality.
There are some macros related to align or restrict, which you could define(away) in your application. As for CLZ, the application can define it for now. Hope this non CMSIS-DSP solution helps.

@felix-johnny Thanks for the response. It makes sense, in that I would expect eyebrows to be raised if someone asked if an Arm hardware library had plans for x86 compatibility. However sometimes it is a lot easier to bring up examples and tests on a host (cough audiomark cough). __CLZ was unique in that there were no other intrinsics exposed, this lead me to believe I was doing something wrong. All good, thanks!
