llvm dev - Apr 2014 - [LLVMdev] Correct way to chain alias analysis passes?

What is the right way to set up chained alias analysis passes?  I'd like to
use both TypeBasedAliasAnalysis and ScalarEvolutionAliasAnalysis.  In the Julia
code that builds the LLVM pass list, I tried the following:

    FPM = new FunctionPassManager(m);
    ...
    jl_TargetMachine->addAnalysisPasses(*FPM);
    FPM->add(createTypeBasedAliasAnalysisPass());
    FPM->add(createScalarEvolutionAliasAnalysisPass());
    ...

But it appears to be running only TypeBasedAliasAnalysis, and when I step
through the code, it appears that TypeBasedAliasAnalysis is chained to
NoAliasAnalysis.
