Spinlock

Spinlock implementation in Go and inline assembler.

Overview

Package spinlock provides a low level implementation of spinlock in assembly. Also, it provides fallback to implementation based on built-in atomics.

On my private laptop benchmark results are the following. Measured time is wall time.

The fastest implementation based on free function Lock()/Unlock(). However, it is two times slower than spinlock implemented in modern C++.
