1559/** @def RT_LIKELY
1560 * Give the compiler a hint that an expression is very likely to hold true.
1561 *
1562 * Some compilers support explicit branch prediction so that the CPU backend
1563 * can hint the processor and also so that code blocks can be reordered such
1564 * that the predicted path sees a more linear flow, thus improving cache
1565 * behaviour, etc.
1566 *
1567 * IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1568 * this compiler feature when present.
1569 *
1570 * A few notes about the usage:
1571 *
1572 * - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1573 *
1574 * - Generally, use RT_UNLIKELY() with error condition checks (unless you
1575 * have some _strong_ reason to do otherwise, in which case document it),
1576 * and/or RT_LIKELY() with success condition checks, assuming you want
1577 * to optimize for the success path.
1578 *
1579 * - Other than that, if you don't know the likelihood of a test succeeding
1580 * from empirical or other 'hard' evidence, don't make predictions unless
1581 * you happen to be a Dirk Gently character.
1582 *
1583 * - These macros are meant to be used in places that get executed a lot. It
1584 * is wasteful to make predictions in code that is executed rarely (e.g.
1585 * at subsystem initialization time) as the basic block reordering that this
1586 * affects can often generate larger code.
1587 *
1588 * - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1589 * and RT_UNLIKELY(). Should you wish for prediction free status checks,
1590 * use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1591 *
1592 *
1593 * @returns the boolean result of the expression.
1594 * @param expr The expression that's very likely to be true.
1595 * @see RT_UNLIKELY
1596 */

1603 * @param expr The expression that's very unlikely to be true.

1606 * @deprecated Please use RT_LIKELY() instead wherever possible! That gives us
1607 * a better chance of the windows compilers to generate favorable code

1609 * if-case is more likely than the else-case.
