 375  * Function exit tracing
 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.)
