The GNU Compiler Collection (GCC) includes front ends for C, C++, Objective-C,
Fortran, Java, and Go, as well as libraries for these languages (libstdc++,
libgcj,...).
Import gcc-4.7.0 and lang/gcc47 GCC 4.7.0 is a major release, containing substantial new functionality not available in GCC 4.6.x or previous GCC releases. GCC 4.7 features support for software transactional memory on selected architectures. The C++ compiler supports a bigger subset of the new ISO C++11 standard such as support for atomics and the C++11 memory model, non-static data member initializers, user-defined literals, alias-declarations, delegating constructors, explicit override and extended friend syntax. The C compiler adds support for more features from the new ISO C11 standard. GCC now supports version 3.1 of the OpenMP specification for C, C++ and Fortran. The link-time optimization (LTO) framework has seen improvements with regards to scalability, stability and resource needs. Inlining and interprocedural constant propagation have been improved. GCC 4.7 now supports various new GNU extensions to the DWARF debugging information format, like entry value and call site information, a typed DWARF stack and a more compact macro representation. Extending the widest support for hardware architectures in the industry, GCC 4.7 gains support for Adapteva's Epiphany processor, National Semiconductor's CR16, and TI's C6X as well as Tilera's TILE-Gx and TILEPro families of processors. The x86 family support has been extended by the Intel Haswell and AMD Piledriver architectures. ARM has gained support for the Cortex-A7 family.
