08/01/2022, 6:05 PMThis may be a stupid question, but why would Compose be a backend plugin? Doesn’t it just generate cache boxes, generate if statements for recomposition, and tie together composable functions? Why would it need to interact with raw JVM bytecode/LLVM bitcode?

You are mostly right, but frontend plugins operate on FIR while it gets created (and before it is converted to IR) and backend plugins operate on IR, before optimization passes and bytecode transforms

+ I believe there are no alternatives for at least one extension point Compose compiler uses just yet
