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, Cobol, Rust, and Algol 68 front-ends are under development too. GCC includes support for OpenMP, OpenACC and Static Analysis.
