That would mean that PR28690 screwed up two-address machines big.  In that case
my opinion of the patch would change.

Still, I don't think a target hook is the solution.  Even if it adds hack over
hack, having the "funny precedence" rules only before reload could be a
solution.

I'm pretty sure that we are talking about two different things. :-)
