1712/** @def RT_LIKELY
1713 * Give the compiler a hint that an expression is very likely to hold true.
1714 *
1715 * Some compilers support explicit branch prediction so that the CPU backend
1716 * can hint the processor and also so that code blocks can be reordered such
1717 * that the predicted path sees a more linear flow, thus improving cache
1718 * behaviour, etc.
1719 *
1720 * IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1721 * this compiler feature when present.
1722 *
1723 * A few notes about the usage:
1724 *
1725 * - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1726 *
1727 * - Generally, use RT_UNLIKELY() with error condition checks (unless you
1728 * have some _strong_ reason to do otherwise, in which case document it),
1729 * and/or RT_LIKELY() with success condition checks, assuming you want
1730 * to optimize for the success path.
1731 *
1732 * - Other than that, if you don't know the likelihood of a test succeeding
1733 * from empirical or other 'hard' evidence, don't make predictions unless
1734 * you happen to be a Dirk Gently character.
1735 *
1736 * - These macros are meant to be used in places that get executed a lot. It
1737 * is wasteful to make predictions in code that is executed rarely (e.g.
1738 * at subsystem initialization time) as the basic block reordering that this
1739 * affects can often generate larger code.
1740 *
1741 * - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1742 * and RT_UNLIKELY(). Should you wish for prediction free status checks,
1743 * use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1744 *
1745 *
1746 * @returns the boolean result of the expression.
1747 * @param expr The expression that's very likely to be true.
1748 * @see RT_UNLIKELY
