 Notably, unlike the previously stabilized `x86` and `x86_64` intrinsics, these do not have a safety requirement to only be called when the appropriate target feature is enabled. This is because WebAssembly was written from the start to validate code safely before executing it, so instructions are guaranteed to be decoded correctly (or not at all).
 
-This means that we can expose some of the intrinsics as entirely safe functions, for example [`v128_bitselect`](https://doc.rust-lang.org/beta/core/arch/wasm32/fn.v128_bitselect.html). However, there are still some intrinsics which are unsafe, such as [`v128_load`](https://doc.rust-lang.org/beta/core/arch/wasm32/fn.v128_load.html).
