After r255321, clang uses libc++ by default. This leads to a lot of

errors when you enable WITH_GNUCXX to build libstdc++, since it will include C++ headers from the libc++ installation under ${WORLDTMP}, and those are not compatible with libstdc++ at all. To fix this, add -stdlib=libstdc++ to CXXFLAGS when building libstdc++ (and its companion libsupc++) with clang. Approved by: re (delphij)

Add compiler support for the ARM EABI.

ARM EABI support is disabled by default and can be enabled by setting WITH_ARM_EABI when building, however only the kernel-toolchain target will work with this flag until the rest of the support is added.

GCC defines built-ins for atomic instructions found on i486 and higher.

2010-09-07T08:33:17Z

Because FreeBSD no longer supports the 80386 cpu all code targeting FreeBSD/i386 necessarily runs on i486 or higher so the compiler built-ins can be used by default inside libstdc++ and in C++ headers. This allows newly compiled C++ code to inline some atomic operations. Old binaries continue to use libstdc++ functions.
