Can we make a Rust program that’s as small as it’s assembler equivalent?
You must log in or register to comment.
That assembly program the author compares to is waay bloated. This guy managed with 105 bytes: https://nathanotterness.com/2021/10/tiny_elf_modernized.html (that is with overlapping part of the code into the ELF header and other similar level shenanigans). ;)
All kidding aside, interesting article.
i think nothing can outperform simple asm for simple operations.
IDK, I’m not aware of all the fancy asm commands, but compilers are, so a good compiler will probably produce better code than me. For example, simple loops could turn into a set of SIMD instructions or be unrolled, while I’d naively do a jump loop.
