--- Comment #3 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
I haven't looked deeply into this, but prior to Richi's PRE patch in r239414 we
had a CMOV instruction.  So if anything, Richi's patch removes the problematic
instruction.  It is with Bernd's patch tweaking costs in r242832 that we get
the CMOV again.

Could Bernd or someone else take a look at the cost patch to see if it's
something  simple that backend experts can tackle?
