This revision is now accepted and ready to land.

If we're in a world where unwinders can handle the offset expression, but not actually restoring SVE registers, I guess this is the best we can do. LGTM

> Yes, great spot! The caller should assume that all SVE registers are clobbered by the unwinder if the function _may_ throw an exception. I think I'll create a separate patch to fix this, as it's not necessarily something to do with how LLVM emits the unwind info, but rather a bug where the caller doesn't honour the right CC.

Okay.  I'd like to see a corresponding change to the ABI document.
