lib.rs:

#intel-tsx-hle This crate provides atomic intrinsics for HLE (Hardware Lock Elision) on some Intel Skylake CPUs in 32-bit (x86) and 64-bit (x86_64) modes. The naming of the intrinsics follows that in Andi Kleen's tsx-tools. Intrinsics are available for u8, u16, u32, and, for x86_64, u64. These intrinsics can be thought of as providing additional memory orderings to Rust's Relaxed, Release, Acquire and SeqCst. They closely model the intent of GCC's built in atomic instrincs.
