Wow. I used my own stack switch routine for several years now and didn't realize it could be improved until I read this thread. Thank you very much.

This is my old naive version:

You are missing x/y/zmm regs in the clobber list.

Yes, that's true. However in my app this has never caused any problems. Apparently even if the compiler auto-vectorizes anything it does this only with scratch regs or in leaf procedures. I don't have any fp or simd code of myself.
