Surely you read the article?
"The requirement from the start was byte-for-byte identical output from both pipelines. "
The bytecode from C++ is identical to the Rust output.
~~I don't think it's possible to write rust code that compiles to the exact same binary as c++. compilers make different optimizations, and make overall a different structure, especially across languages.~~
~~I think they meant the rust library produces the same output from the same input as the c++ library.~~
if llms indeed generate worse rust code than for other languages, that's not that big of a problem because the compiler will catch a lot of mistakes. if it compiles, it will run, and no memory safety bugs unless unsafe is also used. the llm could pick the wrong functions for some uses, but that should be caught relatively easily with testing, which can be automated partly
edit: I was wrong, they indeed say that. this is weird.
