I was posting it for Steve's benefit really. I was in the process of
updating the patch to the trunk and trying it out there before doing a
formal submission :). As I found out the testcase needs to be changed
to work with the new mips target test infrastructure. I will post a
revised patch with the removal of the internal bug number once I
finish fixing the testcase itself.
