Google released and enhanced version of gcc-4.2.1 plus their local patches for Android[1]. The patches are owned by Google and the license hasn't been changed from the original GPLv2. We are only bringing a subset of the available patches that may be helpful in FreeBSD. Changes specific to android are not included. From the README.google file[1]. Patches applied to google_vendor_src_branch/gcc/gcc-4.2.1: gcc/Makefile.in gcc/c-common.c gcc/c-common.h gcc/c-opts.c gcc/c-typeck.c gcc/cp/typeck.c gcc/doc/invoke.texi gcc/flags.h gcc/opts.c gcc/tree-flow.h gcc/tree-ssa-alias-warnings.c gcc/tree-ssa-alias.c Backport of -Wstrict-aliasing from mainline. Silvius Rus <rus@google.com> gcc/coverage.c: Patch coverage_checksum_string for PR 25351. Seongbae Park <spark@google.com> Not yet submitted to FSF. gcc/c-opts.c gcc/c-ppoutput.c gcc/c.opt gcc/doc/cppopts.texi libcpp/Makefile.in libcpp/directives-only.c libcpp/directives.c libcpp/files.c libcpp/include/cpplib.h libcpp/init.c libcpp/internal.h libcpp/macro.c Support for -fdirectives-only. Ollie Wild <aaw@google.com>. Submitted to FSF but not yet approved. libstdc++-v3/include/ext/hashtable.h http://b/742065 http://b/629994 Reduce min size of hashtable for hash_map, hash_set from 53 to 5 libstdc++-v3/include/ext/hashtable.h http://b/629994 Do not iterate over buckets if hashtable is empty. gcc/common.opt gcc/doc/invoke.texi gcc/flags.h gcc/gimplify.c gcc/opts.c Add Saito's patch for -finstrument-functions-exclude-* options. gcc/common.opt gcc/doc/invoke.texi gcc/final.c gcc/flags.h gcc/opts.c gcc/testsuite/gcc.dg/Wframe-larger-than.c Add a new flag -Wframe-larger-than- which enables a new warning when a frame size of a function is larger than specified. This patch hasn't been integrated into gcc mainline yet. gcc/tree-vrp.c Add a hack to avoid using ivopts information for pointers starting at constant values.

README |
file: libstdc++-v3/README New users may wish to point their web browsers to the file documentation.html in the 'docs/html' subdirectory. It contains brief building instructions and notes on how to configure the library in interesting ways. Instructions for configuring and building appear in docs/html/install.html. This directory contains the files needed to create an ISO Standard C++ Library. It has subdirectories: docs Files in HTML and text format that document usage, quirks of the implementation, and contributor checklists. include All header files for the C++ library are within this directory, modulo specific runtime-related files that are in the libsupc++ directory. include/std Files meant to be found by #include <name> directives in standard-conforming user programs. include/c Headers intended to directly include standard C headers. [NB: this can be enabled via --enable-cheaders=c] include/c_std Headers intended to include standard C headers, and put select names into the std:: namespace. [NB: this is the default, and is the same as --enable-cheaders=c_std] include/bits Files included by standard headers and by other files in the bits directory. include/backward Headers provided for backward compatibility, such as <iostream.h>. They are not used in this library. include/ext Headers that define extensions to the standard library. No standard header refers to any of them. scripts Scripts that are used during the configure, build, make, or test process. src Files that are used in constructing the library, but are not installed. testsuites/[backward, demangle, ext, performance, thread, 17_* to 27_*] Test programs are here, and may be used to begin to exercise the library. Support for "make check" and "make check-install" is complete, and runs through all the subdirectories here when this command is issued from the build directory. Please note that "make check" requires DejaGNU 1.4 or later to be installed. Please note that "make check-script" calls the script mkcheck, which requires bash, and which may need the paths to bash adjusted to work properly, as /bin/bash is assumed. Other subdirectories contain variant versions of certain files that are meant to be copied or linked by the configure script. Currently these are: config/abi config/cpu config/io config/locale config/os In addition, two subdirectories are convenience libraries: libmath Support routines needed for C++ math. Only needed if the underlying "C" implementation is non-existent, in particular required or optimal long double, long long, and C99 functionality. libsupc++ Contains the runtime library for C++, including exception handling and memory allocation and deallocation, RTTI, terminate handlers, etc. Note that glibc also has a bits/ subdirectory. We will either need to be careful not to collide with names in its bits/ directory; or rename bits to (e.g.) cppbits/. In files throughout the system, lines marked with an "XXX" indicate a bug or incompletely-implemented feature. Lines marked "XXX MT" indicate a place that may require attention for multi-thread safety.
