obtained gcc-4.6.4.tar.bz2 from upstream website;upstream

verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+# This test is known to fail on targets that use the instruction scheduler
+# at optimisation levels of 2 or more because the alias analysis is confused
+# by the reassignment of a variable structure to a fixed structure.  The 
+# failure could be suppressed by preventing instruction scheduling:
+#
+# set additional_flags "-fno-schedule-insns2";
+#
+# but this would disguise the fact that there is a problem.  Instead we use
+# we generate an xfail result and explain that it is alias analysis that
