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 <stddef.h>, <sys/queue.h>, and <sys/types.h> // 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. Note that in // more recent ELF binutils, we use .ident allowing the ID to be stripped. // Usage: // __FBSDID("$FreeBSD$"); // - // The following definitions are an extension of the behavior originally // implemented in <sys/_posix.h>, but with a different level of granularity. // POSIX.1 requires that the macros we test be defined before any standard // header file is included. // // Here's a quick run-down of the versions: // defined(_POSIX_SOURCE) 1003.1-1988 // _POSIX_C_SOURCE == 1 1003.1-1990 // _POSIX_C_SOURCE == 2 1003.2-1992 C Language Binding Option // _POSIX_C_SOURCE == 199309 1003.1b-1993 // _POSIX_C_SOURCE == 199506 1003.1c-1995, 1003.1i-1995, // and the omnibus ISO/IEC 9945-1: 1996 // _POSIX_C_SOURCE == 200112 1003.1-2001 // _POSIX_C_SOURCE == 200809 1003.1-2008 // // In addition, the X/Open Portability Guide, which is now the Single UNIX // Specification, defines a feature-test macro which indicates the version of // that specification, and which subsumes _POSIX_C_SOURCE. // // Our macros begin with two underscores to avoid namespace screwage. // Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1. // Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2. // Deal with various X/Open Portability Guides and Single UNIX Spec. // Deal with all versions of POSIX. The ordering relative to the tests above is // important. // - // Deal with _ANSI_SOURCE: // If it is defined, and no other compilation environment is explicitly // requested, then define our internal feature-test macros to zero. This // makes no difference to the preprocessor (undefined symbols in preprocessing // expressions are defined to have value zero), but makes it more convenient for // a test program to print out the values. // // If a program mistakenly defines _ANSI_SOURCE and some other macro such as // _POSIX_C_SOURCE, we will assume that it wants the broader compilation // environment (and in fact we will never get here). // User override __EXT1_VISIBLE // Old versions of GCC use non-standard ARM arch symbols; acle-compat.h // translates them to __ARM_ARCH and the modern feature symbols defined by ARM. // Nullability qualifiers: currently only supported by Clang. // Type Safety Checking // // Clang provides additional attributes to enable checking type safety // properties that cannot be enforced by the C type system. // Lock annotations. // // Clang provides support for doing basic thread-safety tests at // compile-time, by marking which locks will/should be held when // entering/leaving a functions. // // Furthermore, it is also possible to annotate variables and structure // members to enforce that they are only accessed when certain locks are // held. // Structure implements a lock. // Function acquires an exclusive or shared lock. // Function attempts to acquire an exclusive or shared lock. // Function releases a lock. // Function asserts that an exclusive or shared lock is held. // Function requires that an exclusive or shared lock is or is not held. // Function should not be analyzed. // Function or variable should not be sanitized, e.g., by AddressSanitizer. // GCC has the nosanitize attribute, but as a function attribute only, and // warns on use as a variable attribute. // Guard variables and structure members by lock. // Alignment builtins for better type checking and improved code generation. // Provide fallback versions for other compilers (GCC/Clang < 10): // - // SPDX-License-Identifier: BSD-2-Clause-FreeBSD // // Copyright (c) 2002 Mike Barcroft <mike@FreeBSD.org> // All rights reserved. // // Redistribution and use in source and binary forms, with or without // modification, are permitted provided that the following conditions // are met: // 1.
