The environments are MINGW64 and MINGW32 (the original MinGW-w64 environments using gcc, msvcrt, and libstdc++), UCRT64 (adaptation of MINGW64 to ucrt), and CLANG64 (adaptation of UCRT64 to clang and libc++). While Cygwin also provides MinGW-w64 compilers and libraries, the set of available libraries is smaller, and they are not as easily ...
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.
The C standard library, sometimes referred to as libc, [1] is the standard library for the C programming language, as specified in the ISO C standard. [2] Starting from the original ANSI C standard, it was developed at the same time as the C POSIX library, which is a superset of it. [3]
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 6.7 on powerpc. [61] 12 October 2020 Clang 11.0.0 released: 21 December 2020
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 ...
The actual size and behavior of floating-point types also vary by implementation. The only requirement is that long double is not smaller than double, which is not smaller than float. Usually, the 32-bit and 64-bit IEEE 754 binary floating-point formats are used for float and double respectively.
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 .
The C++ for OpenCL language is not documented in a stand-alone document and it is based on the specification of C++ and OpenCL C. The open source Clang compiler has supported C++ for OpenCL since release 9. [28] C++ for OpenCL has been originally developed as a Clang compiler extension and appeared in the release 9. [29]
