One of the best techniques for using LLM coding is to let it write programs that frontload and automate work in a repeatable and testable manner rather than letting it only do free form turns.

Letting it generate machine code directly would be the opposite of that.

You can't PGO that code, though. Also, I'm not sure it can generate architecture specific optimized (-march, -mtune) code as well.

Considering it just pulls and remixes blocks, this is a very tall order for today's LLMs, and maybe a couple of generations as well.

Calling GCC/clang at the back and emitting ASM is both cheating and has no advantages whatsoever as well.

This is like saying that a strong man would rather dig a hole with his bare hands than use a shovel. Structured programming languages are force multipliers, it makes absolutely zero sense to forego them just so you can vibe assembly directly.

Use a working Go program as the prompt+oracle for cross-language port or direct generation.
