FYI:

I mostly ported GCC 4.5 to the BSD Makefiles (svn head sys/gnu/usr.bin/cc) for
ARM. Basically, I added the FreeBSD format extension, the __FreeBSD_cc_version
built-in define and the PATH changes. I did not make BSD Makefile for the
GMP and MPFR libraries. I don't have the FreeBSD-8.0 revision 195697 that
eliminates ".text relocations in shared libraries compiled with stack
protector".

Vassilis Laganakos has been working with GCC 4.4 on the ARM.

I haven't push the compiler (and newer binutils 2.19) much beyond building
the kernel. GCC 4.5 "-O" option creates new kernel warnings with the
conditional locks. Below is a typical error:
