| 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. | |
