E.g. In Cygwin, a header file can be found in /usr/include that sub-includes a file of the same name in /usr/include/sys. Not everything is defined in there but some definitions are done by references to the GNU C standard library headers (like stddef.h) which provide the type size_t and many more. Thus, unistd.h is only a generically defined ...
C's offsetof() macro is an ANSI C library feature found in stddef.h. It evaluates to the offset (in bytes) of a given member within a struct or union type, an expression of type size_t . The offsetof() macro takes two parameters , the first being a structure or union name, and the second being the name of a subobject of the structure/union that ...
Clang – The free Clang project includes a static analyzer. As of version 3.2, this analyzer is included in Xcode. [14] Infer – Developed by an engineering team at Facebook with open-source contributors. Targets null pointers, leaks, API usage and other lint checks.
Clang becomes default compiler in OpenBSD 6.6 on mips64. [58] 19 September 2019 Clang 9.0.0 released with official RISC-V target support. [59] 29 February 2020 Clang becomes the only C compiler in the FreeBSD base system, with the removal of GCC. [60] 24 March 2020 Clang 10.0.0 released: 2 April 2020: Clang becomes default compiler in OpenBSD 6 ...
Mingw-w64 includes a port of the GNU Compiler Collection (GCC), GNU Binutils for Windows (assembler, linker, archive manager), a set of freely distributable Windows specific header files and static import libraries for the Windows API, a Windows-native version of the GNU Project's GNU Debugger, and miscellaneous utilities.
The combination of the Clang frontend and LLVM backend is named Clang/LLVM or simply Clang. The name LLVM was originally an initialism for Low Level Virtual Machine . However, the LLVM project evolved into an umbrella project that has little relationship to what most current developers think of as a virtual machine .
C17, formally ISO/IEC 9899:2018, [1] is an open standard for the C programming language, prepared in 2017 and published in July 2018. It replaced C11 (standard ISO/IEC 9899:2011), [2] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. [3]
In computer programming, a precompiled header (PCH) is a (C or C++) header file that is compiled into an intermediate form that is faster to process for the compiler.Usage of precompiled headers may significantly reduce compilation time, especially when applied to large header files, header files that include many other header files, or header files that are included in many translation units.
