 /**
  * compiler - macros for common compiler extensions
  *
  * Abstracts away some compiler hints.  Currently these include:
- * - UNLIKELY_FUNCTION_ATTRIBUTE
+ * - COLD
  *	For functions not called in fast paths (aka. cold functions)
- * - PRINTF_ATTRIBUTE
+ * - PRINTF_FMT
  *	For functions which take printf-style parameters.
- * - IDEMPOTENT_ATTRIBUTE
+ * - CONST_FUNCTION
  *	For functions which return the same value for same parameters.
- * - NEEDED_ATTRIBUTE
+ * - NEEDED
  *	For functions and variables which must be emitted even if unused.
- * - UNNEEDED_ATTRIBUTE
+ * - UNNEEDED
  *	For functions and variables which need not be emitted if unused.
- * - IS_COMPILE_CONSTANT
+ * - UNUSED
+ *	For parameters which are not used.
+ * - IS_COMPILE_CONSTANT()
  *	For using different tradeoffs for compiletime vs runtime evaluation.
