cdefs.h@ 68862

Last change on this file since 68862 was 68572, checked in by vboxsync, 7 years ago
merging vbglioc r117744: iprt: Introducing RT_FAR and friends to deal with the world of 16-bit compilers. Made iprt/types.h somewhat 16-bit safe (explicit far pointers, int type fixes).
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

1561	/** @def RT_LIKELY
1562	* Give the compiler a hint that an expression is very likely to hold true.
1563	*
1564	* Some compilers support explicit branch prediction so that the CPU backend
1565	* can hint the processor and also so that code blocks can be reordered such
1566	* that the predicted path sees a more linear flow, thus improving cache
1567	* behaviour, etc.
1568	*
1569	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1570	* this compiler feature when present.
1571	*
1572	* A few notes about the usage:
1573	*
1574	* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1575	*
1576	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1577	* have some _strong_ reason to do otherwise, in which case document it),
1578	* and/or RT_LIKELY() with success condition checks, assuming you want
1579	* to optimize for the success path.
1580	*
1581	* - Other than that, if you don't know the likelihood of a test succeeding
1582	* from empirical or other 'hard' evidence, don't make predictions unless
1583	* you happen to be a Dirk Gently character.
1584	*
1585	* - These macros are meant to be used in places that get executed a lot. It
1586	* is wasteful to make predictions in code that is executed rarely (e.g.
1587	* at subsystem initialization time) as the basic block reordering that this
1588	* affects can often generate larger code.
1589	*
1590	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1591	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1592	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1593	*
1594	*
1595	* @returns the boolean result of the expression.
1596	* @param expr The expression that's very likely to be true.
1597	* @see RT_UNLIKELY
