llvm dev - Nov 2016 - Memory Dependency Analysis

Hello all,
I'm using the *DependenceAnalysisWrapperPass* to compute memory
dependencies between instructions. However, for the following code, it
finds no dependencies at all.
Is this Pass working?

define i32 @foo(i32 %a, float %b) {
  %1 = alloca i32, align 4
  store i32 %a, i32* %1, align 4
  %2 = load i32, i32* %1, align 4
  ret i32 %2
}

I also noticed that there is a *MemoryDependenceAnalysis* Pass. Which one
should I use?

Thanks,
Juan
