ICE producer

I have built a cross-compiler toolchain for sh64 that can also compile for 32-bit SH.  All the 32-bit Linux kernel SH defconfigs that I've fed it have worked, but the primary 64-bit SH defconfig fails with a gcc SEGV/ICE on at least one of the files.

I've distilled the C code that produced the ICE down to a few lines (see attachment).  This is compiled with:

sh64-linux-gnu-gcc -m5-32media-nofpu -ml -Wa,-isa=shmedia -O2 -c ice.c
ice.c: In function ‘part_pack_uuid’:
ice.c:8:3: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla/> for instructions.

The gcc build was configured with:

From gcc-4.7.0-RC-20120302.tar.bz2 downloaded from the gcc website.

The binutils used was binutils-2.22.52.0.1.tar.bz2 with the patches from the Fedora rawhide binutils srpm applied.  This was configured thusly:

LDFLAGS='-Wl,-z,relro ' \
../binutils-2.22.52.0.1/configure --disable-dependency-tracking --disable-silent-rules --enable-checking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu --target=sh64-elf --program-prefix=sh64-linux-gnu- --disable-shared --enable-64-bit-bfd --enable-targets=sh64-linux,sh-elf,sh-linux,sh4-linux --with-bugurl=http://bugzilla.redhat.com/bugzilla/

And a symlink emplaced at /usr/sh64-linux to point to the /usr/sh64-elf/ directory  so that the cross-compiler could find it.

For reference, the cross-gcc and cross-binutils are built as RPMs for Fedora using spec files or SRPMs similar to those that can be found in http://people.redhat.com/~dhowells/cross/
