I can confirm that c6 is vulnerable, we're running a patched kernel
(local build) using a rhel6 adaptation of the upstream fix.

Side-channel resistant values
Hi Chandler,
I feel like this conversation has come full circle. So to ask again: how does one force CMOV to be emitted? You suggested “__builtin_unpredictable()” but that gets lost in various optimization passes. Given other architectures have CMOV like instructions, and given the usefulness of the instruction for performance tuning, it seems like a direct intrinsic would be best. What am I missing?
