Hi all, I am implementing a new pass for LLVM which extends Call Graph SCCPass. I need DominatorTree Information when I get to individual function. I have added AU.addrequired<DominatorTree>() and AU.addRequired<DominanceFrontier>() in getAnalysisUsage() function. But, when I get to the pass, Pass Manager gives following runtime error Unable to schedule 'Dominator Tree

LLVMers, I am doing a CallGraphPass but would like to get the LoopInfo of the functions inside this pass, is this possible? Currently I have a function inside the CallGraph struct: void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addPreserved<LoopInfo>(); } And...

...) and I passed a reference (&F) (F is a function pointer). I still get the opt load error from the original message (UNREACHABLE exectuted!). Thanks.

1. Ok will do. 2. Ok, will do. 3. It's a CallGraphPass. I mentioned this in my first post. 4. Yep, I have the header files included, I'm not sure it would compile otherwise (previously).

...e to schedule 'Natural Loop Information' required by '......' **** Google led me to this page, where Devang Patel suggests implementing the addLowerLevelRequiredPasses in CGPassManager in a manner similar to MPPassManager. http://old.nabble.com/DominatorTree-Information-required-in-CallGraphPass-td 21968640.html I tried this but to get analysis passes on the fly I need to use FunctionPassManagerImpl in CallGraphSCCPass.cpp which I cannot because it is not part of any header file. I tried using FunctionPassManager but it does not implement getOnTheFlyPass() required by getAnalysis(). I al...

...edural Register Allocator (IPRA henceforth). 1. Decide if we have to create MachineCallGraphSCCPass. 2. If we have to create MachineCallGraphSCCPass, inherit from CallGraphSCCPass and override the methods as required. 3. Create a new IPRA pass which inherits from MachineCallGraphSCCPass or CallGraphPass depending on whether we create MachineCallGraphSCCPass. 4. Implement a loop in runOnMachineSCC that iterates over the CallGraph nodes in the bottom-up order: A. For each node, run one of the allocators as chosen by the command line flag or the optimization level required. This can b...
