cdefs.h@ 63687

Last change on this file since 63687 was 63413, checked in by vboxsync, 8 years ago
iprt/cdefs.h: Changed RTCALL to use cdecl (and regparm) in the GCC/x86 case to avoid the wine/windef.h redefinition of cdecl that reders it useless.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

1559	/** @def RT_LIKELY
1560	* Give the compiler a hint that an expression is very likely to hold true.
1561	*
1562	* Some compilers support explicit branch prediction so that the CPU backend
1563	* can hint the processor and also so that code blocks can be reordered such
1564	* that the predicted path sees a more linear flow, thus improving cache
1565	* behaviour, etc.
1566	*
1567	* IPRT provides the macros RT_LIKELY() and RT_UNLIKELY() as a way to utilize
1568	* this compiler feature when present.
1569	*
1570	* A few notes about the usage:
1571	*
1572	* - Generally, order your code use RT_LIKELY() instead of RT_UNLIKELY().
1573	*
1574	* - Generally, use RT_UNLIKELY() with error condition checks (unless you
1575	* have some _strong_ reason to do otherwise, in which case document it),
1576	* and/or RT_LIKELY() with success condition checks, assuming you want
1577	* to optimize for the success path.
1578	*
1579	* - Other than that, if you don't know the likelihood of a test succeeding
1580	* from empirical or other 'hard' evidence, don't make predictions unless
1581	* you happen to be a Dirk Gently character.
1582	*
1583	* - These macros are meant to be used in places that get executed a lot. It
1584	* is wasteful to make predictions in code that is executed rarely (e.g.
1585	* at subsystem initialization time) as the basic block reordering that this
1586	* affects can often generate larger code.
1587	*
1588	* - Note that RT_SUCCESS() and RT_FAILURE() already makes use of RT_LIKELY()
1589	* and RT_UNLIKELY(). Should you wish for prediction free status checks,
1590	* use the RT_SUCCESS_NP() and RT_FAILURE_NP() macros instead.
1591	*
1592	*
1593	* @returns the boolean result of the expression.
1594	* @param expr The expression that's very likely to be true.
1595	* @see RT_UNLIKELY

3551	/** @def WORKAROUND_MSVC7_ERROR_C2593_FOR_BOOL_OP
3552	* Macro to work around error C2593 of the not-so-smart MSVC 7.x ambiguity
3553	* resolver. The following snippet clearly demonstrates the code causing this
3554	* error:
3555	* @code
3556	* class A
3557	* {
3558	* public:
3559	* operator bool() const { return false; }
3560	* operator int*() const { return NULL; }
3561	* };
3562	* int main()
3563	* {
3564	* A a;
3565	* if (!a);
3566	* if (a && 0);
3567	* return 0;
3568	* }
3569	* @endcode
3570	* The code itself seems pretty valid to me and GCC thinks the same.
3571	*
3572	* This macro fixes the compiler error by explicitly overloading implicit
3573	* global operators !, && and \|\| that take the given class instance as one of
3574	* their arguments.
3575	*
3576	* The best is to use this macro right after the class declaration.
3577	*
3578	* @note The macro expands to nothing for compilers other than MSVC.
3579	*
