Where do you read that I'm talking about emulating popcount in software?
I mean exactly the opposite.
If you need to support all B, or a subgroup of B, you can choose to put popcount in hardware and emulate the other instructions.

This is neither a source nor an argument.

Because you wrote this: > Did you know that it's stipulated in the RISC-V spec that instructions not present in the hardware can be emulated in software? apparently in reference to the B extension which includes popcount.
