391  * bad form, but having a separate exit macro before the actual return
392  * is very ugly and difficult to maintain.
393  *
394  * One of the FUNCTION_TRACE macros above must be used in conjunction
395  * with these macros so that "_AcpiFunctionName" is defined.
396  *
397  * There are two versions of most of the return macros. The default version is
398  * safer, since it avoids side-effects by guaranteeing that the argument will
399  * not be evaluated twice.
400  *
401  * A less-safe version of the macros is provided for optional use if the
402  * compiler uses excessive CPU stack (for example, this may happen in the
403  * debug case if code optimization is disabled.)
