That fixed the test case. Thanks. I didn't know about the PowerPC-specific %U
thing, but now I see that the compiler did the right thing.
Seems like the descriptions of "m" and "es" in the PowerPC-specific part of
md.texi are now a bit stale: "es" should be equivalent to "m", and "m" should
be safe (free of side-effects) unless accompanied by "<" or ">".
