So why is the peephole not working in its current location?

Hi Jeff,
that is what I read out of dumps:
If peephole2 is executed early we see following pattern transformation:
[ ... ]
Ask an ARM maintainer if the new code is actually better than the old code.
It appears that with the peep2 pass moved that we actually if-convert
the fall-thru path of the conditional and eliminate the conditional.
Which, on the surface seems like a good thing. It may be the case that
we need to twiddle the test. Not sure yet.
