Which reminds me, are we going in and out of SSA during
inter-procedural optimizations? The flow I sort of have in my
1 create call graph
2 convert bodies to SSA form
3 do interprocedural tree optimizations
4 do intraprocedural tree optimizations
5 convert call graph to RTL
I can see how that can be expensive, but it would mean that we
only go out of SSA in step #5.
