Re: Confused, SPARC vulnerable or not?

"What part of Spectre being a hardware bug did you fail to understand? If a chip is vulnerable it doesn't matter what software you are running on it."

It appears to be theoretically possible to defeat those attacks with suitably crafted software, but that's a case of running new binaries - and likely some kind of hit in performance. The big.little boxes out there could run sensitive processes on an in-order processor - and the less sensitive workload on faster OOO cores.
