Hi, everyone,

I would like to know if anyone is still making use of the support in the PowerPC backend for the IBM BG/Q supercomputer, including the support for its QPX vector instruction set. If you are, please reply. I'm not aware of any still-running BG/Q machines, and if no one is making use of this functionality, I propose that we remove it.

Thanks again,
