[LLVMdev] Can a Function Pass require a Module Pass?

Dear LLVMers,

I am implementing a Function Pass and I would like to use analysis obtained
from a Module Pass. Some extracts of my code look like that:

    struct MyPass : public FunctionPass {
        static char ID;
        MyPass() : FunctionPass(ID) {
            PADriver &PD = getAnalysis<AModulePass>();

        virtual void getAnalysisUsage(AnalysisUsage &AU) const{

But when I try to run my pass, I get the following error at the point os

 Assertion `Resolver && "Pass has not been inserted into a PassManager
object!"' failed.

Did I do anything I should not or did I miss something?
