Gerald Pfeifer 04bfaa8ecd Update the default version of GCC used in the Ports Collection from ... GCC 4.6.4 to GCC 4.7.3. This entails updating the lang/gcc port as well as changing the default in Mk/bsd.default-versions.mk. This adds powerpc64 as a supported architecture (and removes ia64, though it can be supported by manually installing lang/gcc48). New binaries %%GNU_HOST%%-gcc-ar47, %%GNU_HOST%%-gcc-nm47, and %%GNU_HOST%%-gcc-ranlib47 are provided to support link-time optimization (LTO) which scales significantly better. And it adds support for indirect functions (IFUNCS), experimental support for transactional memory in the compiler as well as a supporting run-time library called libitm, a new string length optimization pass, and support for atomic operations specifying the C++11/C11 memory model. Version 3.1 of the OpenMP specification is now supported for the C, C++, and Fortran compilers. GCC accepts the options -std=c11 and -std=gnu11 for the C11 revision of the ISO C standard which inlcude support for unicode strings, nonreturning functions (_Noreturn and <stdnoreturn.h>), alignment support (_Alignas, _Alignof, max_align_t, <stdalign.h>), and a __builtin_complex built-in function. The C++ frontend now accepts the -std=c++11, -std=gnu++11, and -Wc++11-compat options and implements many C++11 features of the language including extended friends syntax, explicit override control, non-static data member initializers, user-defined literals, alias declarations, delegating constructors, atomic classes, and more. The C++ standard library and Fortran frontend have received many improvements. See http://gcc.gnu.org/gcc-4.7/changes.html for an extense list of changes; http://gcc.gnu.org/gcc-4.7/porting_to.html for information on how to port to that new version.
