I've found that in 4.1, -fno-web is often needed in order to generate
auto-increment addressing.
I suppose that will be similar for any live range splitting that happens before
flow.
Well, is that something you have to blame live range splitting for, or
is perhaps flow just too stupid to see through the split live ranges?
Actually, Zadeck is working on a new auto-increment pass anyway IIUC.
