--- Comment #2 from Michael Meissner <meissner at gcc dot gnu.org> ---
I guess it is late on a Friday, and I mixed up compilers or options.
I verified that with subversion id 248266 that compiling the attachment with
-mcpu=power9 -O3 -ffast-math DOES NOT generate vector instructions, while
compiling it with -mcpu=power8 -O3 -ffast-math DOES generate vector
instructions.
It also does not generate vector instructions when using the -mcpu=power7 -O3
-ffast-math option.
