  376.  *
  377.  * These macros include a return statement. This is usually considered
  378.  * bad form, but having a separate exit macro before the actual return
  379.  * is very ugly and difficult to maintain.
  380.  *
  381.  * One of the FUNCTION_TRACE macros above must be used in conjunction
  382.  * with these macros so that "_AcpiFunctionName" is defined.
  383.  *
  384.  * There are two versions of most of the return macros. The default version is
  385.  * safer, since it avoids side-effects by guaranteeing that the argument will
  386.  * not be evaluated twice.
  387.  *
  388.  * A less-safe version of the macros is provided for optional use if the
  389.  * compiler uses excessive CPU stack (for example, this may happen in the
  390.  * debug case if code optimzation is disabled.)
