0353  * bad form, but having a separate exit macro before the actual return
0354  * is very ugly and difficult to maintain.
0355  *
0356  * One of the FUNCTION_TRACE macros above must be used in conjunction
0357  * with these macros so that "_AcpiFunctionName" is defined.
0358  *
0359  * There are two versions of most of the return macros. The default version is
0360  * safer, since it avoids side-effects by guaranteeing that the argument will
0361  * not be evaluated twice.
0362  *
0363  * A less-safe version of the macros is provided for optional use if the
0364  * compiler uses excessive CPU stack (for example, this may happen in the
0365  * debug case if code optimization is disabled.)
