to GCC 4.8.3. This entails updating the lang/gcc port as well as changing the default in Mk/bsd.default-versions.mk, and it replaces the CONFLICT between the lang/gcc and lang/gcc47 ports by lang/gcc48. GCC now uses C++ as its implementation language and performs more aggressive loop analysis which can be disabled via the -fno-aggressive-loop-optimizations command-line option. Compilation of extremely large functions has been signficantly improved, as have interprocedural optimizations. A new optimization level -Og has been introduced. It addresses the need for fast compilation and a superior debugging experience while providing a reasonable level of run-time performance. This should be better suitable for development than the default -O0. A new local register allocator (LRA) has been implemented, which replaces the 26 year old reload pass and improves generated code quality. For now it is active on the x86 and x86-64 targets. AddressSanitizer, a fast memory error detector, has been added and can be enabled via -fsanitize=address. Each diagnostic emitted now includes the original source line and a caret indicating the column. The new option -Wpedantic is an alias for -pedantic, which is now deprecated. The C++ frontend and associated run-time library libstdc++ have gained support for many additional C++11 features. As with previous releases the Fortrand frontend has seen many improvements as well. Support for the AArch64 has been added, and there are many improvements to the x86/x86-64 backend and others. See http://gcc.gnu.org/gcc-4.8/changes.html for an extense list of changes; http://gcc.gnu.org/gcc-4.8/porting_to.html for information on how to port to that new version.
