62	* Macro for checking if an I/O or MMIO emulation call succeeded.
63	*
64	* This macro shall only be used with the IOM APIs where it's mentioned
65	* in the return value description. And there it must be used to correctly
66	* determine if the call succeeded and things like the RIP needs updating.
67	*
68	*
69	* @returns Success indicator (true/false).
70	*
71	* @param rc The status code. This may be evaluated
72	* more than once!
73	*
74	* @remarks To avoid making assumptions about the layout of the
75	* VINF_EM_FIRST...VINF_EM_LAST range we're checking explicitly for
76	* each exact exception. However, for efficiency we ASSUME that the
77	* VINF_EM_LAST is smaller than most of the relevant status codes. We
78	* also ASSUME that the VINF_EM_RESCHEDULE_REM status code is the
79	* most frequent status code we'll enounter in this range.
80	*
81	* @todo Will have to add VINF_EM_DBG_HYPER_BREAKPOINT if the
82	* I/O port and MMIO breakpoints should trigger before
83	* the I/O is done. Currently, we don't implement these
84	* kind of breakpoints.
