GNU Compiler Collection (GCC)

GNU compilers

The GNU Compiler Collection (GCC) is an optimizing compiler produced by the GNU Project supporting various programming languages, hardware architectures and operating systems. It includes front-ends for C, C++, D, Objective-C, Fortran, Ada, and Go, as well as libraries for these languages (such as libgcc and libstdc++). Modula-2, Rust, Cobol, and Algol 68 front-ends are under development too. GCC includes a Static Analyzer, and supports OpenMP, OpenACC with code offloading to Nvidia and AMD GPUs.
