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.

# bsd.gcc.mk - Support for smarter USE_GCC usage.
|
|
#
|
|
# Created by: Edwin Groothuis <edwin@freebsd.org>
|
|
#
|
|
# To request the use of a current version of GCC, specify USE_GCC=yes in
|
|
# your port/system configuration. This is the preferred use of USE_GCC.
|
|
# It defines a canonical, default version of GCC.
|
|
#
|
|
# USE_GCC=any is similar, except that it also accepts the old GCC 4.2-
|
|
# based system compiler in older versions of FreeBSD.
|
|
#
|
|
# If your port needs a specific (minimum) version of GCC, you can easily
|
|
# specify that with a USE_GCC= statement. Unless absolutely necessary
|
|
# do so by specifying USE_GCC=X.Y+ which requests at least GCC version
|
|
# X.Y. To request a specific version omit the trailing + sign.
|
|
#
|
|
# Examples:
|
|
# USE_GCC= yes # port requires a current version of GCC
|
|
# # (4.7 as of today, subject to change).
|
|
# USE_GCC= any # port requires GCC 4.2 or later.
|
|
# USE_GCC= 4.8+ # port requires GCC 4.8 or later.
|
|
# USE_GCC= 4.8 # port requires GCC 4.8.
|
|
#
|
|
# If you are wondering what your port exactly does, use "make test-gcc"
|
|
# to see some debugging.
