--- Comment #2 from Dominik Mierzejewski  ---
No need to apologise. I'm not very familiar, either. They're not drop-in
replaceable. YASM seems to support GAS syntax, while NASM does not.
Feature-wise, I think NASM supports all current x86_64 extensions up to AVX512
while YASM does not (e.g. https://github.com/yasm/yasm/issues/101). It
shouldn't be too difficult to either drop the requirement or port to NASM.
