How check my CPU vector features are being used?

[OddLingo]

I have built whisper on a RISCV platform that supports RVV1.0 as well as some NPU things. I see that there is code in GGML that can take advantage of this through compiler intrinsics provided the right modules are selected at link time and the correct conditional compilations are taken. How can I check that these are in fact being used instead of some generic C code? The reason I ask is that when I run the JFK sample through whisper-cli it is spending 89% of its time in the 'encode' phase and taking nearly 3x the duration of the input audio.
