Lots of languages at a higher level than C are closer to the processor in that they have interfaces for more instructions that C hasn't standardized yet.

Well, you're talking about languages that don't have standards, they have a reference implementation.

IOW, no language has standards for processor intrinsics; they all have implementations that support intrinsics.
