...*if* a pass requests an AliasAnalysis group pass *and* your pass has already been executed, the pass requesting an AliasAnalysis group pass will find your pass and use it. That is why you need to add it explicitly. If you don't add it explicitly, the PassManager will simply use the default AliasAnalisys group pass, which I believe is BasicAA.

Hi ! In my quest of implementing my own AA, i understood that it doesn't work because i don't use the 'opt' tool but i create my own PassManager (this for other reasons). The problem is the same with other existing AA (AndersensPass or globalModRefPass) : these AApasses are not chained with the basicAA when they are created in PassManager ... So my question is now : how to

Hi ! I'm writting an AliasAnalysis using the online tutorial (http://www.llvm.org/docs/AliasAnalysis.html). My problem is to chain this pass (function Pass in my case) with the basicAA ... I know that my pass is running (runOnFunction) but the virtual methods derived from AliasAnalysis (alias, getModRefInfo, etc ... ) are never called (even in the case wherer the basicAA reaches the end
