This crates provides a simple set of wrappers around Intel's TSX RTM instructions and associated intrinsics. It needs a C compiler to create a small shim. This is important because Rust's compiler does not like code with multiple returns. It does not depend on your compiler having the necessary headers (<immintrin.h>), and so can work with older compilers and other Operating Systems.
It uses third-party self-modifying code (Andi Kleen's tsx-tools) to provide runtime detection of CPUs without TSX and fallback to non-hardware paths.
