Detailed Description

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.
