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.)
