--- Comment #2 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
Actually, the code you get for -mcpu=power6 looks "fine." The originally
reported problem was for use of stvewx to store single vector elements, rather
than using stvx to store entire vectors. This is now happening for
-mcpu=power6. By the way, you get the same code if you use -mcpu=power7
-mno-vsx, as the xvdivsp instruction requires the VSX feature.
So in my view we can probably close this one as a WORKSFORME at this point.
