It helps to aid in // having a compiler-agnostic source tree. // Compiler memory barriers, specific to gcc and clang. // XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced // Macro to test if we're using a specific version of gcc or later. // The __CONCAT macro is used to concatenate parts of symbol names, e.g. // with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo. // The __CONCAT macro is a bit tricky to use if it must work in non-ANSI // mode -- there must be no spaces between its arguments, and for nested // __CONCAT's, all the __CONCAT's must be at the left. __CONCAT can also // concatenate double-quoted strings produced by the __STRING macro, but // this only works with ANSI C. // // __XSTRING is like __STRING, but it expands any macros in its argument // first. It is only available with ANSI C. // Compiler-dependent macros to help declare dead (non-returning) and // pure (no side effects) functions, and unused variables. They are // null except for versions of gcc that are known to support the features // properly (old versions of gcc-2 supported the dead and pure features // in a different (wrong) way). If we do not provide an implementation // for a given compiler, let the compile fail if it is told to use // a feature that we cannot live without. // Keywords added in C11. // Emulation of C11 _Generic(). Unlike the previously defined C11 // keywords, it is not possible to implement this using exactly the same // syntax. Therefore implement something similar under the name // __generic(). Unlike _Generic(), this macro can only distinguish // between a single type, so it requires nested invocations to // distinguish multiple cases. // C99 Static array indices in function parameter declarations. Syntax such as: // void bar(int myArray[static 10]); // is allowed in C99 but not in C++. Define __min_size appropriately so // headers using it can be compiled in either language. Use like this: // void bar(int myArray[__min_size(10)]); // XXX: should use `#if __STDC_VERSION__ < 199901'. // C++11 exposes a load of C99 stuff // GCC 2.95 provides `__restrict' as an extension to C90 to support the // C99-specific `restrict' type qualifier. We happen to use `__restrict' as // a way to define the `restrict' type qualifier without disturbing older // software that is unaware of C99 keywords. // GNU C version 2.96 adds explicit branch prediction so that // the CPU back-end can hint the processor and also so that // code blocks can be reordered such that the predicted path // sees a more linear flow, thus improving cache behavior, etc. // // The following two macros provide us with a way to utilize this // compiler feature. Use __predict_true() if you expect the expression // to evaluate to true, and __predict_false() if you expect the // expression to evaluate to false. // // A few notes about usage: // // * Generally, __predict_false() error condition checks (unless // you have some _strong_ reason to do otherwise, in which case // document it), and/or __predict_true() `no-error' condition // checks, assuming you want to optimize for the no-error case. // // * Other than that, if you don't know the likelihood of a test // succeeding from empirical or other `hard' evidence, don't // make predictions. // // * These are meant to be used in places that are run `a lot'. // It is wasteful to make predictions in code that is run // seldomly (e.g. at subsystem initialization time) as the // basic block reordering that this affects can often generate // larger code. // We define this here since , , and // require it. // Given the pointer x to the member m of the struct s, return // a pointer to the containing structure. When using GCC, we first // assign pointer x to a local variable, to check that its type is // compatible with member m. // Compiler-dependent macros to declare that functions take printf-like // or scanf-like arguments. They are null except for versions of gcc // that are known to support the features properly (old versions of gcc-2 // didn't permit keeping the keywords out of the application namespace). // Compiler-dependent macros that rely on FreeBSD-specific extensions. // Embed the rcs id of a source file in the resulting library.
