/**
 * @brief Check for macro definition in compiler-visible expressions
 *
 * This trick was pioneered in Linux as the config_enabled() macro.
 * The madness has the effect of taking a macro value that may be
 * defined to "1" (e.g. CONFIG_MYFEATURE), or may not be defined at
 * all and turning it into a literal expression that can be used at
 * "runtime".  That is, it works similarly to
 * "defined(CONFIG_MYFEATURE)" does except that it is an expansion
 * that can exist in a standard expression and be seen by the compiler
 * and optimizer.  Thus much ifdef usage can be replaced with cleaner
 * expressions like:
 *
 *     if (IS_ENABLED(CONFIG_MYFEATURE))
 *             myfeature_enable();
 *
 * INTERNAL
 * First pass just to expand any existing macros, we need the macro
 * value to be e.g. a literal "1" at expansion time in the next macro,
 * not "(1)", etc...  Standard recursive expansion does not work.
 */
#define IS_ENABLED(config_macro) _IS_ENABLED1(config_macro)

/* Now stick on a "_XXXX" prefix, it will now be "_XXXX1" if config_macro
 * is "1", or just "_XXXX" if it's undefined.
 *   ENABLED:   _IS_ENABLED2(_XXXX1)
 *   DISABLED   _IS_ENABLED2(_XXXX)
 */
#define _IS_ENABLED1(config_macro) _IS_ENABLED2(_XXXX##config_macro)

/* Here's the core trick, we map "_XXXX1" to "_YYYY," (i.e. a string
 * with a trailing comma), so it has the effect of making this a
 * two-argument tuple to the preprocessor only in the case where the
 * value is defined to "1"
 *   ENABLED:    _YYYY,    <--- note comma!
 *   DISABLED:   _XXXX
 *   DISABLED:   _XXXX0
 */
#define _XXXX1 _YYYY,
#define _XXXX0

/* Then we append an extra argument to fool the gcc preprocessor into
 * accepting it as a varargs macro.
 *                         arg1   arg2  arg3
 *   ENABLED:   _IS_ENABLED3(_YYYY,    1,    0)
