[LLVMdev] How to get LoopInfo within Pass subclass?
...y. This is likely to be an
oversimplified view, but hopefully it's a start.
1 - in add(), discover that the pass we're requiring is a subpass, and
create more of them.
This is the natural place to do it, but can we do this here, or do we
not know enough about the passes?
2 - in addPass(SubPassClass, ...), add those FPs to CurrentAnalyses.
Should we have a map of BatcherClasses - (function, BatcherClass) pairs
instead of just one BatcherClass?
3 - Provide API for the MP to get an analysis per function. (generally,
for the PassClass to get analysis per SubPassClass):
Instead of this:
getAna...

...on, the pass manager would have to clone not just the B
objects, but also the A objects for every function.
The other tricky thing is that we don't know how many pass objects to
create until we actuall start running the pass manager (it depends on the
module being run on).

I'm not sure about this. At the time add is called, you don't know what
the functions are. I think that the correct solution is to...

Yeah, this sounds like the key problem.
