[James A Simmons]

I just tested your latest patch. Works perfectly. Thank you.

[Dmitry Eremin (Inactive)]

Hmm. I cannot check this. James, can you provide the fix or just description what is not handled properly? What value of target_cpu should be handled?

[James A Simmons]

Also for RHEL7 on power8 the target_cpu is not handled in our build system.
