Hi! I can't build LLVM using GCC 4.1 (GCC CVS mainline) after http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050328/025003.html Build terminated with error: /home/wanderer/pkg/build/llvm/src/llvm/lib/Target/SparcV9/ModuloScheduling/DependenceAnalyzer.cpp:25: error: explicit qualification in declaration of `llvm::FunctionPass* llvm::createDependenceAnalyzer()' at line:

I though LiveVariables may be invalidated by LiveIntervals, but it's declared not: void LiveIntervals::getAnalysisUsage(AnalysisUsage &AU) const { AU.addPreserved<LiveVariables>(); AU.addRequired<LiveVariables>(); ... LiveInterval may coalesce virtual registers and remove identity moves instructions: bool LiveIntervals::runOnMachineFunction(MachineFunction &fn) {

Hi, I am using llvm-3.8 for my project. Following is my getAnalysisUsage() method: virtual void getAnalysisUsage(AnalysisUsage &AU) const override { AU.setPreservesAll(); AU.addRequired<X>(); AU.addRequired<Y>(); AU.addRequired<Z>(); } Now, if I call getAnalysis<X>(*F), instead of invoking just the X pass, all the passes, i.e., X, Y and Z are being

I have added -debug-pass=Structure, and found the following: ModulePass Manager X Analysis Unnamed pass: implement Pass::getPassName() FunctionPass Manager Module Verifier Bitcode Writer Pass Arguments: -x -y -z FunctionPass Manager X Analysis Y Construction Z Construction Even for getAnalysis<Y>(*F) and getAnalysis<Z>(&F), all the passes X,

Hello, I have discovered a situation in which the pass manager will infinite loop. The minimal test case is below this message. The required structure of these passes is; Before requires CallGraph After requires LoopSimplify and Before I can observe this through opt: opt -load ./libBug.so -after input.bc -o output.bc I built my copy of llvm from svn revision 68820 using gcc 4.1.2 Any

Dear all, Hi! I encounter an interesting assertion failure when implementing my Pass, which is defined with the member functions shown below: ======================My Pass====================================== bool MYPass::runOnModule(Module &M) { for (auto &F : M) { SE = &getAnalysis<ScalarEvolutionWrapperPass>(F).getSE(); ......

Hi, I am trying to use the DependenceAnalysis pass to get the Distance vector for the innermost loop. I am in LLVM learing process. I have used the following code inside my original code to get the distance vector. It is not giving any syntax error but it is has some logical but and giving segmentation fault. void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll();

Hi all, I am getting the infamous error: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not " "'required' by pass!"' but i really don't understand why. I have: voidInstrumentationPass::getAnalysisUsage(llvm::AnalysisUsage&AU) const{     AU.setPreservesAll();     AU.addRequired<DetectKernelsPass>();    

How do you compile the code? Within the Polly subdirectory using CMake? How do you run your pass. Using "opt -mypass inputfile.ll"?

Hi, I'm trying to use the function getAnalysis. This is the code I'm using : void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequired<LoopInfo>(); AU.setPreservesAll(); } virtual bool runOnModule(Module &M) { LoopInfo &LI = getAnalysis<LoopInfo>(); } I get following error when I try to run my pass : opt:

Hi LLVM community, I am writing a custom pass for analyzing the dependence information for the memory access within a loop. I found “LoopAccessLegacyAnalysis” class useful, however I m not able to obtain information from that pass. Here is what I did to get the information: // require pass virtual void getAnalysisUsage(AnalysisUsage &AU) const {

I would have thought this would have been possible.

See http://llvm.org/docs/GettingStarted.html#brokengcc and then try building with something OTHER than GCC 4.1.2 . ----- Original Message ---- > From: Nick Johnson <npjohnso at cs.princeton.edu> > To: LLVM Developers Mailing List <llvmdev at cs.uiuc.edu> > Sent: Monday, May 11, 2009 3:01:12 PM > Subject: [LLVMdev] Pass Manager hangs with CallGraph and LoopSimplify >

Hello, I need to analyze dependencies in my llvm ir by using polly. i created a new pass called mypass there i added polly dependency analysis pass but when i execute this pass in gdb i get no data. Why is that so? My code is follows; namespace { struct mypass : public FunctionPass { static char ID; mypass() : FunctionPass(ID) { } virtual bool runOnFunction(Function &F) {

The following code is causing an "UNREACHABLE executed!" and a stack dump, any ideas? namespace { struct myPass : public CallGraphSCCPass { static char ID; myPass() : CallGraphSCCPass(ID) {} virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll(); AU.addRequired<LoopInfo>(); } virtual bool runOnSCC(CallGraphSCC &SCC)

There are some funny errors that can occur when you do things that the PassManager cannot handle. For example, if you're requiring a transform pass, that can cause strange assertions from the

Dear guys, I need help fixing a little piece of code. I have a pass that I really want to execute after the TwoAddressinstructionPass. But if I write "AU.addRequiredID(TwoAddressInstructionPassID);" in my pass' getAnalysisUsage, I end up getting the infamous: PassManagerT.h:387: failed assertion `getAnalysisOrNullUp(P) &&
