I would rather have LLM directly generate machine code, and best of all, macro Assemblers are blazing fast for decades.

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.

		That is fighting the last war on the early days of 5 GLs, and taken care by agentic runtimes. This isn't futurology, besides a few projects that already came up on Phoronix and around here, with Assembly generation, there are enough SIGPLAN papers on ML driven compilers already.
