@mcr229 - @larryliu0820 and I discussed this a bit in other context. But there might be an apatite to solve this at ET level which can work for all the delegates. A simplest approach might be to generate some metadata along with each preprocess which can be consumed at delegate compile time. Parsing delegate blob can be an another, rather tedious, alternative.

@digantdesai there would be some level of support on the XNNPACK side in order to selectively choose right?

[digantdesai]

Yeah, we would need to upstream some support but I can imagine if we only need int8 ops then we can compile time turn off FP32, FP16 etc.
