About:
LibatomicOps provides a portable and highly optimized implementation of atomic memory update operations. It serves as a foundational library for building concurrent and garbage-collected programming runtimes. Its primary value is abstracting away low-level, hardware-specific instructions for atomic operations.

Key Features:

Portable API for atomic operations
Architecture-specific optimizations
Support for various memory models
Low-level primitives for runtime development

Use Cases:

Implementing custom garbage collectors
Building high-performance concurrent data structures
Developing language runtimes requiring atomic primitives

Alternatives:

C11 <stdatomic.h> – Standardized C11 interface, often preferred for new projects unless targeting older compilers or specific runtime needs.
GCC/Clang __atomic Builtins – Compiler-provided intrinsics offering similar functionality without an external library dependency.
