Is there any reason that we don't have isLoopSimplifyForm method in LoopBase? Can I move it there? -Kuba -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20110728/95b007e3/attachment.html>

Hello, I'm working on integrating the MachinePipeliner.cpp pass into our VLIW backend, and so far we've managed to get it working with some nice speedups. Unlike Hexagon however, our backend doesn't generate hardware loop instructions and so all our loops are a combination of induction variables, comparisons and branches. So when it came to implementing reduceLoopCount for our

Thank you, Nick. Yes, I have add getAnalysisUsage. As I know, some CFG is irreducible. At this time, Dominator Tree can not find some backedge. Is it means some MachineLoop is not be found? dominatorTree.jpg is a previous exmaple. best regards! renkun --- 10年3月9日，周二, Nick Lewycky <nicholas at mxc.ca> 写道： > 发件人: Nick Lewycky <nicholas at mxc.ca> > 主题: Re: [LLVMdev] Find

Hi:    I want to do some optimization on MachineLoop. So I want to get MachineLoopInfo from MachineFunction. I reference MachineLICM.cpp. So I try to write a pass in Target/mytarget directory. I find there is Error. llvm/include/llvm/PassAnalysisSupport.h:198: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::MachineLoopInfo]: Assertion
