When doing feature detection for execution path selection, it’s sometimes useful to run some quick benchmarks to see which path is objectively best. Now we have two-ish implementations or x86, but back in the 1980s and 1990s we had quite a few, some with wildly different performance characteristics. And, if we talk about ARM and RISC-V, we’ll have an order of magnitude more.
