I think it's inappropriate for you to overrule Ian without trying to
build consensus, given that this is a change to the IA32 back end.  You
have GWP, and Ian does not, so it is true that you can change i386.h
without approval, and that Ian cannot; in that sense, you outrank Ian.

But, I think Ian's comment:

suggests a path forward which is no harder than the one posted, but
considerably clearer, as well as avoiding code duplication.

Why not ask Mike to make that change?
