Hi, I'm trying to detect if a basicblock is part of a loop or not. I tried the llvm::LoopInfo like that (http://llvm.org/docs/doxygen/html/classllvm_1_1LoopInfo.html#a4abca289c73cd09487e05d11d9f7d877): LoopInfo *loop = new LoopInfo(); bool isLoop = loop->getLoopFor(myBB); // getLoopFor - Return the inner most loop that BB lives in. If a basic block is in no loop (for example the entry node), null is returned. See doxygen But getLoopFor() always retur...

...mous. If you want to see if an SSA value is defined within a loop, you would use the LoopInfo pass to determine if the basic block containing the instruction defining the value of interest belongs to the loop that interests you. Information on LoopInfo can be found at http://llvm.org/doxygen/classllvm_1_1LoopInfo.html. -- John T. > > Thanks, > Rohith.

Hi , I'm working on a project in which i need to find out all free variables in a loop. I need to find all variables used inside a loop and that are not declared(allocated) in the loop. I'm confused about what symbol tables to use to get hold of such variables. Thanks, Rohith. -------------- next part -------------- An HTML attachment was scrubbed... URL:

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.
