Yes! This tripped me up at one point. My comment says "Otherwise we could be in the bizarre special-case of 3-argument CMP instructions." https://github.com/mmcloughlin/avo/blob/0e253b3753beb409b3dd8028fc81f5fa4b96aaee/internal/opcodescsv/analysis.go#L84 https://github.com/mmcloughlin/avo/blob/0e253b3753beb409b3dd... It gets to the point where the only source of truth is the Go assembler itself. My test suite takes the avo instruction database and generates a massive assembly file with one line per instruction form, then passes this to `go tool asm`.
