How can I vmjc to run CallGraphSCCPasses? I wrote a test pass that does nothing, and all vmjc says is: vmjc: PassManager.cpp:1604: virtual void llvm::ModulePass::assignPassManager(llvm::PMStack&, llvm::PassManagerType): Assertion `!PMS.empty() && "Unable to find appropriate Pass Manager"' failed. 0 vmjc 0x08a6bfd8 Aborted Running even a built in pass like prune-eh fails as well. From what I can tell, this is because the only PassManager on...

Here is some informative output. Seems to me the problem is in stripping the symbols of the assignPassManager virtual method from the various subclasses of llvm::Pass.

...I need some BasicBlock that contains the error routine. So I tried to create a ModulePass to insert some basic block e. g. in the beginning of the program, to use it for the jne-instruction. Unfortunately, llc then produces the error llc: PassManager.cpp:1597: virtual void llvm::ModulePass::assignPassManager(llvm::PMStack&, llvm::PassManagerType): Assertion `!PMS.empty() && "Unable to find appropriate Pass Manager"' failed. Adding a MachineFunctionPass the same way works fine. I've read here on the mailing list that some Pass dependencies cause this error, but I hav...

Hi all, I was able to create a pass following [1]. Now goal is amend the pass and try to dump the call graph. I think I have properly amended the source extending my pass from CallGraphSCCPass but unfortunately every time I run it, it crashes. I tried with llvm-6 and llvm-7. I notice that if I change EP_EarlyAsPossible to anything else it does not crash but I don't see the expected string

Hi Michael, +CC llvm-dev My guess is that it would be rather error prone to pinpoint exact places where we start populating new LPPassManager since it’s created lazily via LoopPass::assignPassManager. So we are risking to miss adding verifiers in some of the LPPassManager’s. One similar idea is to introduce LCSSAVerifier function pass and make LCSSA pass to be dependant on it. That will allow me to check ‘getAnalysisIfAvaliable<LCSSAVerifier>’ inside of the LPPassManager and explicitl...

Hi, I am trying to use the poolallocator. More specific, I am trying to play around with the pointer compression pass. Though, I get assertion failures for the pass dependencies. This is when it in PointerCompress::getAnalysisUsage tries to register the the BU pass as required. I.e. when AU.addRequired<CompleteBUDataStructures>(); is called. $ opt -f -load
