Re: “JavaScript” instructions. I think it means FJCVTZS which is not Apple specific and only yields a fairly minor improvement. It’s not even really that JS specific, it’s definitely designed to help with JS numbers but it’s not like a large chunk of JS functionality is in silicon. The memory ordering stuff is cool, calling it cheating might be a bit harsh although it would be cool if other ARM cores would support something like this.
