Hello All, There is an issue in AddressSanitizer today because it depends on it's doFinalization method be called before the Printer method to output the final code (that is the printer runOnModule call). This assumption seems invalid as the doFinalization method should AFAIK only be used for clean up tasks independent of activities of other passes. When I try to call doFinalization inside the MPPassManager::runOnModule method (to avoid changing the API to add doInitialization and doFinaliz...

Hi Duncan, thanks for the quick answer. Yes I'm sure the runOnModule is being called, and when I dump the functions before exiting the method I can see the AlwaysInline attribute. I'll check InlineAlways.cpp and will reimplement as last resource but I still wonder why this is not working. On Mon, Nov 5, 2012 at 5:03 PM, Duncan Sands <baldrick at free.fr&g...

Thanks so much John! That works :) Previously I wrote a pass that inherited from CallGraphWrapperPass and used its getCallGraph() function within runOnModule() which resulted in segmentation faults for me. Not sure why that happened, perhaps callgraph wasn't setup by the time runOnModule() was called internally. If you know why, kindly enlighten me and perhaps document the behavior for the benefit of others. Your email was the best thing to happen...

...we do static lockset analysis. I need to get Aliasing information statically given the .bc file of the application. Is there any library in LLVM which already implements the aliasing? (does it support multi-threaded apps?) What is the best way of doing it (I want to extract aliasing information in runOnModule() function in the pass I am working on)?

As far as I can see your code should work. Most likely it isn't being run at all - did you check that your runOnModule method is actually being called?
