Sorry, my first message seems to not have made it out...
Thanks for the review, I posted a v2 patch to the list.

In an embedded application with Tensorflow-lite micro that uses CMSIS-NN
as backend.
I optimized some compute kernels in the backend (think of matrix

leaf functions (every helper is properly inlined), I used this patch to
count the number of executed instructions within the kernels.
Greetings,
Steffen
