It sounds like adding proper support for HLE prefixes is a largeish project.
ctopper, rnk: Do you think it would be worth adding inline asm versions (with the xacquire/release prefixes) of these intrinsics in the meantime? It would inhibit optimizations but be better than the current state of not having the intrinsics at all.
