C compilers are just too smart IMO to make C portable assembly. Your example doesn’t always ADDI either, for example if it is inlined

This isn’t qualitatively different from what the JVM JIT would do, but Java isn’t considered portable assembly.

I guess if you compile with optimizations completely off, you get something that is assembly-like, but I’ve never seen that in prod code.
