...er evolved to not need the topological ordering constraint, so I never revisited the problem. In hindsight, I don't even know if Function guarantees that they are presented in a topological order, but it always happened to be the case for me.

Hi all, I have a question about llvm::LoopBase getBlocks() method. Does it return the basic blocks inside the loop in random order? I need to order the blocks in some valid topological ordering of the AST. If getBlocks() does not do that, what can I do to find the ordering?

Thanks Devang and John. My pass is actually a loop pass, not a function pass. So, I couldnt override the getAnalysisUsage. I am in a loop pass, I know the outermost loop. Now How can I get the loopInfo from here? I couldn't find helpful methods in the LoopInfo class documents.

Hi all, How Can I get the Loops around an Instruction? I know I can get the basic block of an instruction using inst.getParent() which returns a BasicBlock*. Now I want to use the getLoopFor(BasicBlock) method of the class LoopInfo. But I dont know how to get the LoopInfo. BasicBlock* bb = inst.getParent(); (... what should I add here?) Loop* innerloop = LI -> getLoopFor(bb): Thanks.

Hi, I am running into this segmentation fault while running a simple function pass on some C benchmarks Program received signal SIGSEGV, Segmentation fault. 0x00000000005c5c00 in AddReachableCodeToWorklist(llvm::BasicBlock*, llvm::SmallPtrSet<llvm::BasicBlock*, 64u>&, llvm::InstCombiner&, llvm::TargetData const*) () What can be the possible reasons of the segmentation fault here?
