An LLM wrote a C compiler for an old chip in about 90 minutes, near the reference size

Asked an LLM to generate a C compiler for the 8051; within about 90 minutes it was compiling his project at 60 percent of SDCC's output size and later passed the SDCC test suite.

90 minsaved

How it works

  1. He asks an LLM to generate the compiler
  2. Within about 90 minutes it compiles his project at 60 percent of the reference compiler's output size
  3. It later passes the reference test suite

Why it’s worth knowing

Ninety minutes to a compiler that beats the reference on size.
