But why does the same not work with "and" and "or" (-> VANDPS/VORPS) ? Anyway, I am looking forward to testing your patches. Would it be possible to send around a notification when the stuff goes upstream? Thanks a lot :). Best, Ralf

But why does the same not work with "and" and > "or" (-> VANDPS/VORPS) ? It can. Maybe the pattern for ANDPS isn't there yet. I'd have to dig deeper into the failure. The fact that there are inconsistencies like this is one of the motivations behind the SIMD reorg. There are plenty of such inconsistencies in the existing SSE spec. Hopefully after the re...
