I expect the “right” fix might be something involving https://github.com/dotnet/runtime/issues/70182.

Probably. As you know, currently, the problem is with https://github.com/dotnet/runtime/pull/70171, we are doing opposite of reinitializing the constant, and instead trying to “reuse” it. In “reuse” case, we only save/restore upper half if it holds a live variable (and not constant as far as I can tell). I will see if we can patch the save/restore upper half criteria to include it. We might not able to piggyback on the kill refpositions to clear the constants (as I was discussing with Bruce) because the kill positions are per register and in our case, there is no kill refposition inserted for upper-half vector register.
