Detailed Description

This module contains macros for applying specific attributes to functions and variables to control various optimizer and code generation features of the compiler. Attributes may be placed in the function prototype or variable declaration in any order, and multiple attributes can be specified for a single item via a space separated list.

On incompatible versions of GCC or on other compilers, these macros evaluate to nothing unless they are critical to the code's function and thus must throw a compile error when used.

Note:

Do not include this file directly, rather include the Common.h header file instead to gain this file's functionality.
