similar to: [LLVMdev] Infinite loop when adding a new analysis pass

I'm attempting to add some support for hoisting/sinking of memory-using intrinsics in loops, and so I want to use MemoryDependenceAnalysis in LICM, but when I modify getAnalysisUsge to include this : virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesCFG(); AU.addRequired<DominatorTree>(); AU.addRequired<LoopInfo>();

Hi again, I come back to this issue with an example. It's a pass which does nothing but throw the 'Unable to schedule' error. namespace { struct MyPass : public FunctionPass { static char ID; // Pass identification, replacement for typeid MyPass() : FunctionPass(ID) { initializeMyPassPass(*PassRegistry::getPassRegistry()); } virtual void

Hello, I have the following sequence of passes (using --debug-pass=Structure): ...

Hi all, I'm trying to use the PPL (Parma Polyhedra Library, bugseng.com/products/ppl) in one of my LLVM passes getting the error: > Error opening > '/home/jorge/SvnReps/Systems/llvm/build/Debug+Asserts/lib/MyAnalysis.so': > /home/jorge/SvnReps/Systems/llvm/build/Debug+Asserts/lib/MyAnalysis.so: > undefined symbol: _ZNK23Parma_Polyhedra_Library13PIP_Tree_Node2OKEv >

Hi, I'm writing a function pass which is dynamically loaded by opt and I need some analysis and passes to be run before my pass: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.addPreserved<LoopInfo>(); AU.addRequiredID(LoopSimplifyID); AU.addPreservedID(LoopSimplifyID);

I can not open PDf device. Acrobat is closed. I have checked archives but could not find a solution. What should I do? > cont.cdfplot("myanalysis.pdf", myanalysis$CDF, ylbl.r="Stream Length (km)") Error in pdf(file = pdffile, width = width, height = height) : unable to start device pdf In addition: Warning message: In pdf(file = pdffile, width = width, height = height)

Hello I am working on pass which has dependency on multiple passes. Say D1,D2,D3 I used INITIALIZE_PASS_BEGIN INITIALIZE_PASS_DEPENDENCY(D1) INITIALIZE_PASS_DEPENDENCY(D2) INITIALIZE_PASS_DEPENDENCY(D3) INITIALIZE_PASS_END. While running it through opt tool it, I had to specify this D1,D2,D3 pass names to get this pass executed before my pass. Is there way, to let llvm pass manager to know

Dear lazydev, I'm writing an instrumentation pass that depends on AliasAnalysis. My getAnalysisUsage() looks as follows: 2453 void ThreadSanitizer::getAnalysisUsage(AnalysisUsage &AU) const { 2454 AU.addRequired<TargetData>(); 2455 AU.addRequired<AliasAnalysis>(); 2456 } and the pass initialization: 2668 char ThreadSanitizer::ID = 0; 2669

Hi Hongbin I am not quite familiar with AnalysisUsage, let me correct question a bit. I have read Writing Pass <http://llvm.org/docs/WritingAnLLVMPass.html#specifying-interactions-between-passes>, All examples that i see here are based on collecting information .i.e Analysis Passes. I wonder if this applies to Transformation passes also. e.g. void MyInliner::getAnalysisUsage(AnalysisUsage

Hi Alexander, I had the same error: sincos: /home/marcusmae/rpmbuild/BUILD/llvm/lib/VMCore/PassManager.cpp:635: void llvm::PMTopLevelManager::schedulePass(llvm::Pass*): Assertion `PI && "Expected required passes to be initialized"' failed. The solution was to add: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeCore(Registry);

Hi, I am trying to chain two transform passes. ** The first pass is a function pass which requires the 'memory dependence pass' . ** The second pass is a function pass which requires the first pass above. The passes run fine when executed alone. I get the following error when I try to run my second pass with the following code added > > void

Dear list, I've been messing around with coding functions in R and it just won't make sense to me. Running my analysis by hand on command line is fine and works but because of the repetitive nature of the job I would like to code a function for it. My problem: I would like to read in data from a file in my current working dir. so my code would look like: myanalysis <-

When migrating my project to 2.9, I've encountered a strange segfault where if a ModulePass's getAnalysisUsage adds LoopInfo and DominatorTree, then llvm::PMTopLevelManager::findAnalysisUsage will segfault. What's odd is that if I rearrange this (add required for DominatorTree before LoopInfo), it does not segfault. I realize that LoopInfo requires and preserves DominatorTree, but this
