Hi Bill,

> I'm fine with this, but please do the alloca promotion using SSAUpdater soon. Otherwise my horrible hack won't work for all of the cases I need it to. As John mentioned, I need to do reachability and not dominance. I'll fix it so that the DomTree stuff isn't needed.

we never did any alloca promotion at -O0, so does that mean this already
sometimes wasn't working properly at -O0?  Also, I wasn't actually planning
to do alloca promotion for your 'orrible hack code because it makes my head
hurt, but perhaps I can be persuaded...

Ciao,

Duncan.
