[LLVMdev] How to change default AA with opt? (Change default impl for an analysis group with opt?)

I'm working on an AliasAnalysis pass that is loaded as a module.
What I'd like to do is something like:
opt -my-aa -O3
Where -O3 is whatever set of optimizations I'm using, but they all
should use 'my-aa' for their results.
However, what appears to happen is it uses my-aa until something
invalidates those results and then goes back to basic-aa when
something needs AA results again.
Short of running -my-aa -gvn -my-aa -dse -my-aa -licm... etc, is there
a good way to do this?
Having thought about it, it seems less surprising than it did
originally, but perhaps this should be mentioned somewhere?
Thanks for your time,
