They're certainly familiar with assembly itself, but the `asm!` macro and the related constructs in Clang/GCC is its own beast and has a lot of footguns (like GCC allocating registers as overlapping by default). I don't begrudge them writing suboptimal assembly, since it already beat our Rust implementation by a significant margin.
