cdefs.h@ 62938

Last change on this file since 62938 was 62901, checked in by vboxsync, 8 years ago
iprt/cdefs.h: Added RT_NOREF(...) - the C99 version of the RT_NOREFnn() macros. Added a bunch more RT_NOREFnn() macros for stubbed functions with lots of parameters (max is 22 now). This is mainly so RT_NOREF works.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

1543	/** @def RT_LIKELY
1544	* Give the compiler a hint that an expression is very likely to hold true.
1545	*
1546	* Some compilers support explicit branch prediction so that the CPU backend
1547	* can hint the processor and also so that code blocks can be reordered such
1548	* that the predicted path sees a more linear flow, thus improving cache
1549	* behaviour, etc.
1550	*
1551	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1552	* this compiler feature when present.
1553	*
1554	* A few notes about the usage:
1555	*
1556	* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1557	*
1558	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1559	* have some _strong_ reason to do otherwise, in which case document it),
1560	* and/or RT_LIKELY() with success condition checks, assuming you want
1561	* to optimize for the success path.
1562	*
1563	* - Other than that, if you don't know the likelihood of a test succeeding
1564	* from empirical or other 'hard' evidence, don't make predictions unless
1565	* you happen to be a Dirk Gently character.
1566	*
1567	* - These macros are meant to be used in places that get executed a lot. It
1568	* is wasteful to make predictions in code that is executed rarely (e.g.
1569	* at subsystem initialization time) as the basic block reordering that this
1570	* affects can often generate larger code.
1571	*
1572	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1573	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1574	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1575	*
1576	*
1577	* @returns the boolean result of the expression.
1578	* @param expr The expression that's very likely to be true.
1579	* @see RT_UNLIKELY
