The result for x86 cross sh4-unknown-linux-gnu looks similar
to those reported for other targets.  The cross compiler was
configured with

../TMP/lto/configure --host=i686-pc-linux-gnu --target=sh4-unknown-linux-gnu --enable-lto --enable-shared --enable-threads=posix --enable-clocale=gnu --enable-libgcj --with-ld=/usr/local/bin/sh4-unknown-linux-gnu-ld --with-as=/usr/local/bin/sh4-unknown-linux-gnu-as --with-sysroot=/exp/ldroot --with-mpfr=/opt2/i686-pc-linux-gnu --with-gmp=/opt2/i686-pc-linux-gnu --with-mpc=/opt2/i686-pc-linux-gnu --enable-languages=c,c++,fortran,java,objc

The host is Fedora 11 and the version of cross ld is
2.20.51.20090913.
The result of compare_tests against the head
  http://gcc.gnu.org/ml/gcc-testresults/2009-09/msg02758.html
is here.
