On: AVX register corruption from signal delivery

[asveikau]

No, it sounds like it needs the kernel not to corrupt the value. There is nothing wrong with leaving the value in the register.

I believe the aforementioned pointer caching is in the kernel--it's the pointer to the FP register state which is cached across preemption points in the kernel.

Ok I see, that's a good point. Was not spelled out this well in the bug tracker comment. (If it is now it wasn't when I read it.)
