For Sparkplug, bytecode is the input representation. But you’re right that bytecode is an intermediate representation of V8. So to me, whether bytecode is an IR or not depends on whether you’re talking about V8 as a whole or Sparkplug in particular. To me, an intermediate representation is what the compiler translates the input to other than machine code. Sparkplug goes straight from its input (bytecode) to machine code. So you’re not being too pedantic. It’s just that V8 has two compilers now, one that has an IR of its own (turbofan), and one that doesn’t (sparkplug). Lack of IR is one of the things (maybe the most important thing) that makes Sparkplug special. If you define IR in a way that means that bytecode is an IR then I don’t know how to easily articulate what it is that makes Sparkplug special.
