There's no transmute. Look I don't have time for this.

That crate calls transmute twice, for every single instruction. https://github.com/rust-lang-nursery/stdsimd/blob/master/crates/core_arch/src/x86/sse2.rs#L94-L103 https://github.com/rust-lang-nursery/stdsimd/blob/master/cra... https://github.com/rust-lang-nursery/stdsimd/blob/master/crates/core_arch/src/x86/mod.rs#L389-L392 https://github.com/rust-lang-nursery/stdsimd/blob/master/cra...

    Check the actual compiler output.

    What he’s trying to say is that transmute is also an intrinsic. They correspond to the machine instructions, that’s their entire purpose. That’s also why they’re intrinsics.
