1557/** @def RT_LIKELY
1558 * Give the compiler a hint that an expression is very likely to hold true.
1559 *
1560 * Some compilers support explicit branch prediction so that the CPU backend
1561 * can hint the processor and also so that code blocks can be reordered such
1562 * that the predicted path sees a more linear flow, thus improving cache
1563 * behaviour, etc.
1564 *
1565 * IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1566 * this compiler feature when present.
1567 *
1568 * A few notes about the usage:
1569 *
1570 * - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1571 *
1572 * - Generally, use RT_UNLIKELY() with error condition checks (unless you
1573 * have some _strong_ reason to do otherwise, in which case document it),
1574 * and/or RT_LIKELY() with success condition checks, assuming you want
1575 * to optimize for the success path.
1576 *
1577 * - Other than that, if you don't know the likelihood of a test succeeding
1578 * from empirical or other 'hard' evidence, don't make predictions unless
1579 * you happen to be a Dirk Gently character.
1580 *
1581 * - These macros are meant to be used in places that get executed a lot. It
1582 * is wasteful to make predictions in code that is executed rarely (e.g.
1583 * at subsystem initialization time) as the basic block reordering that this
1584 * affects can often generate larger code.
1585 *
1586 * - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1587 * and RT_UNLIKELY(). Should you wish for prediction free status checks,
1588 * use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1589 *
1590 *
1591 * @returns the boolean result of the expression.
1592 * @param expr The expression that's very likely to be true.
1593 * @see RT_UNLIKELY

1601 * @param expr The expression that's very unlikely to be true.

1607 * if-case is more likely than the else-case.
