MFC r286074: GCC: Add a new option "-fstack-protector-strong"
This includes additional functions to be protected: those that have local array definitions, or have references to local frame addresses. This is a new option in GCC-4.9 that was relicensed by Han Shen from Google under GPLv2.

gcc: Add support for -Wmissing-prototypes in C++
Support for warnings about missing prototypes in C++ was added by Apple GCC (Radar 6261539). Most of the code crept into r260311 so it felt natural to make use of it.

MFC r260311, r260831:
gcc: Add support for Apple's Block extension
Block objects [1] are a C-level syntactic and runtime feature. They are similar to standard C functions, but in addition to executable code they may also contain variable bindings to automatic (stack) or managed (heap) memory. A block can therefore maintain a set of state (data) that it can use to impact behavior when executed.
This port is based on Apple's GCC 5646 with some bugfixes from Apple GCC 5666.3. It has some small differences with the support in clang, which remains the recommended compiler.
Perhaps the most notable difference is that in GCC __block is not actually a keyword, but a macro. There may be workaround for this issue in the future. Other issues can be consulted in the clang documentation [2]
For better compatiblity with Apple's GCC and llvm-gcc, some related fixes and features from Apple have been included. Support for the non-standard nested functions in GCC is now off by default.
No effort was made to update the ObjC support since FreeBSD doesn't carry ObjC in the base system but some of the code crept in and was more difficult to remove than to adjust.

GCC: bring back experimental support for amdfam10/barcelona CPUs.
Initial support for the AMD amdfam10 chipsets has been available in the gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10 support and made it available.
This is a revised subset of the support initially brought in in r236962 and later reverted. The collateral efects seem to have disappeared but it is still recommended to set the CPUTYPE with caution.

Add experimental support for amdfam10/barcelona from the GCC 4.3 branch.
Initial support for the AMD barcelona chipsets has been available in the gcc43 branch under GPLv2 but was not included when the Core 2 support was brought to the system gcc.
AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10 support and made them available. Unfortunately this is still experimental and while it can improve performance, enabling the CPUTYPE may break some C++ ports (like clang).
Special care was taken to make sure that the patches predate the GPLv3 switch upstream.

Make gcc use C99 inline semantics in c99 and gnu99 mode. This was the original intent, but the functionality wasn't implemented until after gcc 4.2 was released. However, if you compiled a program that would behave differently before and after this change, gcc 4.2 would have warned you; hence, everything currently in the base system is unaffected by this change. This patch also adds additional warnings about certain inline function-related bogosity, e.g., using a static non-const local variable in an inline function.
These changes were merged from a snapshot of gcc mainline from March 2007, prior to the GPLv3 switch. I then ran the regression test suite from a more recent gcc snapshot and fixed the important bugs it found. I also squelched the following warning unless -pedantic is specified:
foo is static but used in inline function bar which is not static
This is consistent with LLVM's behavior, but not consistent with gcc 4.3.
