- * \brief Compiler specific definitions for code optimization and correctness.
- *
- * Compiler specific definitions to expose certain compiler features which may increase the level of code optimization
- * for a specific compiler, or correct certain issues that may be present such as memory barriers for use in conjunction
- * with atomic variable access.
- *
- * Where possible, on alternative compilers, these macros will either have no effect, or default to returning a sane value
- * so that they can be used in existing code without the need for extra compiler checks in the user application code.
