So across 64-bit ARM and x86-64, what is the ratio of instructions across the same program compiled by effectively the same compiler (modulo of course maturity in code selection and peephole optimization)?
My guess is that x64-64 still saves quite a few pages of memory over 64-bit ARM on a large program.
- stephencanon 11y agoAs an experiment, I built CLAPACK (v3.2) for both arm64 and x86_64 with an up-to-date clang. x86_64 size: 5.2M arm64 size: 4.4M So on at least some large codebases, arm64 looks pretty efficient.
