51 * Macro for checking if an I/O or MMIO emulation call succeeded.
52 *
53 * This macro shall only be used with the IOM APIs where it's mentioned
54 * in the return value description. And there is must be used to correctly
55 * determin if the call succeeded and things like the EIP needs updating.
56 *
57 *
58 * @returns Success indicator (true/false).
59 *
60 * @param rc The status code. This may be evaluated
61 * more than once!
62 *
63 * @remark To avoid making assumptions about the layout of the
64 * VINF_EM_FIRST...VINF_EM_LAST range we're checking
65 * explicitly for each for exach the exceptions.
66 * However, for efficieny we ASSUME that the
67 * VINF_EM_LAST is smaller than most of the relevant
68 * status codes. We also ASSUME that the
69 * VINF_EM_RESCHEDULE_REM status code is the most
70 * frequent status code we'll enounter in this range.
71 *
72 * @todo Will have to add VINF_EM_DBG_HYPER_BREAKPOINT if the
73 * I/O port and MMIO breakpoints should trigger before
74 * the I/O is done. Currently, we don't implement these
75 * kind of breakpoints.
