Depending on the compiler and architecture, it also may be the case that calling conventions differ between the two languages. For these reasons, for C++ code to call a C function foo(), the C++ code must prototype foo() with extern "C". Likewise, for C code to call a C++ function bar(), the C++ code for bar() must be declared with extern "C".
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: Clang becomes default compiler in OpenBSD 6.9 on mips64el. [62] 14 April 2021 Clang ...
Apple has implemented blocks both in their own branch of the GNU Compiler Collection [1] and in the upstream Clang LLVM compiler front end. Language runtime library support for blocks is also available as part of the LLVM project. The Khronos group uses blocks syntax to enqueue kernels from within kernels as of version 2.0 of OpenCL.
The gcc native compiler for machine A (2) is used to build the gcc cross compiler from machine A to machine B (3) The gcc cross compiler from machine A to machine B (3) is used to build the gcc cross compiler from machine B to machine C (4) The end-result cross compiler (4) will not be able to run on build machine A; instead it would run on ...

GCC and clang requires explicit target_clones labels in the code to "clone" functions, [20] while ICC does so automatically (under the command-line option /Qax). The Rust programming language also supports FMV. The setup is similar to GCC and Clang in that the code defines what instruction sets to compile for, but cloning is manually done via ...
The AMD Optimizing C/C++ Compiler (AOCC) is an optimizing C/C++ and Fortran compiler suite from AMD targeting 32-bit and 64-bit Linux platforms. [ 1 ] [ 2 ] It is a proprietary fork of LLVM + Clang with various additional patches to improve performance for AMD's Zen microarchitecture in Epyc , and Ryzen microprocessors.
In May 2010, the GCC steering committee decided to allow use of a C++ compiler to compile GCC. [55] The compiler was intended to be written mostly in C plus a subset of features from C++. In particular, this was decided so that GCC's developers could use the destructors and generics features of C++.
