1637/** @def RT_LIKELY
1638 * Give the compiler a hint that an expression is very likely to hold true.
1639 *
1640 * Some compilers support explicit branch prediction so that the CPU backend
1641 * can hint the processor and also so that code blocks can be reordered such
1642 * that the predicted path sees a more linear flow, thus improving cache
1643 * behaviour, etc.
1644 *
1645 * IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1646 * this compiler feature when present.
1647 *
1648 * A few notes about the usage:
1649 *
1650 * - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1651 *
1652 * - Generally, use RT_UNLIKELY() with error condition checks (unless you
1653 * have some _strong_ reason to do otherwise, in which case document it),
1654 * and/or RT_LIKELY() with success condition checks, assuming you want
1655 * to optimize for the success path.
1656 *
1657 * - Other than that, if you don't know the likelihood of a test succeeding
1658 * from empirical or other 'hard' evidence, don't make predictions unless
1659 * you happen to be a Dirk Gently character.
1660 *
1661 * - These macros are meant to be used in places that get executed a lot. It
1662 * is wasteful to make predictions in code that is executed rarely (e.g.
1663 * at subsystem initialization time) as the basic block reordering that this
1664 * affects can often generate larger code.
1665 *
1666 * - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1667 * and RT_UNLIKELY(). Should you wish for prediction free status checks,
1668 * use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1669 *
1670 *
1671 * @returns the boolean result of the expression.
1672 * @param expr The expression that's very likely to be true.
1673 * @see RT_UNLIKELY
