1576/** @def RT_LIKELY
1577 * Give the compiler a hint that an expression is very likely to hold true.
1578 *
1579 * Some compilers support explicit branch prediction so that the CPU backend
1580 * can hint the processor and also so that code blocks can be reordered such
1581 * that the predicted path sees a more linear flow, thus improving cache
1582 * behaviour, etc.
1583 *
1584 * IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1585 * this compiler feature when present.
1586 *
1587 * A few notes about the usage:
1588 *
1589 * - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1590 *
1591 * - Generally, use RT_UNLIKELY() with error condition checks (unless you
1592 * have some _strong_ reason to do otherwise, in which case document it),
1593 * and/or RT_LIKELY() with success condition checks, assuming you want
1594 * to optimize for the success path.
1595 *
1596 * - Other than that, if you don't know the likelihood of a test succeeding
1597 * from empirical or other 'hard' evidence, don't make predictions unless
1598 * you happen to be a Dirk Gently character.
1599 *
1600 * - These macros are meant to be used in places that get executed a lot. It
1601 * is wasteful to make predictions in code that is executed rarely (e.g.
1602 * at subsystem initialization time) as the basic block reordering that this
1603 * affects can often generate larger code.
1604 *
1605 * - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1606 * and RT_UNLIKELY(). Should you wish for prediction free status checks,
1607 * use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1608 *
1609 *
1610 * @returns the boolean result of the expression.
1611 * @param expr The expression that's very likely to be true.
1612 * @see RT_UNLIKELY

1620 * @param expr The expression that's very unlikely to be true.

1623 * @deprecated Please use RT_LIKELY() instead wherever possible! That gives us
1624 * a better chance of the windows compilers to generate favorable code

1626 * if-case is more likely than the else-case.

3755/** @def WORKAROUND_MSVC7_ERROR_C2593_FOR_BOOL_OP
3756 * Macro to work around error C2593 of the not-so-smart MSVC 7.x ambiguity
3757 * resolver. The following snippet clearly demonstrates the code causing this
3758 * error:
3759 * @code
3760 * class A
3761 * {
3762 * public:
3763 * operator bool() const { return false; }
3764 * operator int*() const { return NULL; }
3765 * };
3766 * int main()
3767 * {
3768 * A a;
3769 * if (!a);
3770 * if (a && 0);
3771 * return 0;
3772 * }
3773 * @endcode
3774 * The code itself seems pretty valid to me and GCC thinks the same.
3775 *
3776 * This macro fixes the compiler error by explicitly overloading implicit
3777 * global operators !, && and || that take the given class instance as one of
3778 * their arguments.
3779 *
3780 * The best is to use this macro right after the class declaration.
3781 *
3782 * @note The macro expands to nothing for compilers other than MSVC.
3783 *
3784 * @param Cls Class to apply the workaround to
