1543/** @def RT_LIKELY
1544 * Give the compiler a hint that an expression is very likely to hold true.
1545 *
1546 * Some compilers support explicit branch prediction so that the CPU backend
1547 * can hint the processor and also so that code blocks can be reordered such
1548 * that the predicted path sees a more linear flow, thus improving cache
1549 * behaviour, etc.
1550 *
1551 * IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1552 * this compiler feature when present.
1553 *
1554 * A few notes about the usage:
1555 *
1556 * - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1557 *
1558 * - Generally, use RT_UNLIKELY() with error condition checks (unless you
1559 * have some _strong_ reason to do otherwise, in which case document it),
1560 * and/or RT_LIKELY() with success condition checks, assuming you want
1561 * to optimize for the success path.
1562 *
1563 * - Other than that, if you don't know the likelihood of a test succeeding
1564 * from empirical or other 'hard' evidence, don't make predictions unless
1565 * you happen to be a Dirk Gently character.
1566 *
1567 * - These macros are meant to be used in places that get executed a lot. It
1568 * is wasteful to make predictions in code that is executed rarely (e.g.
1569 * at subsystem initialization time) as the basic block reordering that this
1570 * affects can often generate larger code.
1571 *
1572 * - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1573 * and RT_UNLIKELY(). Should you wish for prediction free status checks,
1574 * use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1575 *
1576 *
1577 * @returns the boolean result of the expression.
1578 * @param expr The expression that's very likely to be true.
1579 * @see RT_UNLIKELY
1580 */

1587 * @param expr The expression that's very unlikely to be true.

1590 * @deprecated Please use RT_LIKELY() instead wherever possible! That gives us
1591 * a better chance of the windows compilers to generate favorable code

1593 * if-case is more likely than the else-case.

3442 * Macro to work around error C2593 of the not-so-smart MSVC 7.x ambiguity
3443 * resolver. The following snippet clearly demonstrates the code causing this
3444 * error:
3445 * @code
3446 * class A

3449 * operator bool() const { return false; }

3456 * if (a && 0);
3457 * return 0;
3458 * }
3459 * @endcode
3460 * The code itself seems pretty valid to me and GCC thinks the same.
3461 *
3462 * This macro fixes the compiler error by explicitly overloading implicit
3463 * global operators !, && and || that take the given class instance as one of
3464 * their arguments.
3465 *
3466 * The best is to use this macro right after the class declaration.
