Hi, I wrote tiny ModulePass which iterates over functions and then uses getAnalysis<LoopInfo> in order to get informations about the loop. It compiles smoothly, but whenever I try to run it I got error like this: opt: .. PassAnalysisSupport.h:203: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::LoopInfo]: Assertion `ResultPass &&

Hello, I was trying to get the loop info in a module pass to be able to iterate over the loops int the module itself. Since my pass requires to make module level changes including adding new types to module hence a looppass cannot be used here. I am getting the following error on running opt. opt: /root/llvm-2.4/include/llvm/PassAnalysisSupport.h:199: AnalysisType&

Hi, I had a question about this as well. The documentation about writing a pass shows an example like what John wrote, calling a function pass within a module pass on a per function basis. However, if I code it that way, I still get the same error: opt: /x/jeffhao/llvm/llvm/include/llvm/PassAnalysisSupport.h:232: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*,

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:

We have discovered the issue with our code. It seems that when the first call to doInitilization utilized one of the specified analyses, that analysis had never been properly added as required. Using gdb, we can see that addRequired is getting called (seen below) but when doInitalization is finally called, it still responds as if the analysis was not required. Is this a bug or is

Hello, I have created a ModulePass, that now needs LoopInfo information. The ModulePass registration is taken from [1]. I use clang to directly invoke it (This is also a hard requirement, because I need the fancy output of clang warnings/remarks). The problem is, that the dependency to the LoopInfoWrapperPass does not seem to work. The error is: --- snip --- clang-4.0:

Hi, Migrating from 3.5 to 3.9. There is a module pass that uses alias analysis started breaking at runtime: llvm/lnx64/llvm/include/llvm/PassAnalysisSupport.h:236: AnalysisType& llvm::Pass::getAnalysisID(llvm::AnalysisID) const [with AnalysisType = llvm::AAResultsWrapperPass; llvm::AnalysisID = const void*]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was

But this is already present in my pass. And I am not able to understand the cause for the error: opt: /home/ambika/llvm_3/llvm-2.6/include/llvm/PassAnalysisSupport.h:203: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::DominatorTree]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not "

Guys, What I want to do is to hack global opt pass, which needs ScalarEvolution analysis. However opt crashed saying "opt: /home/xchen/llvm/include/llvm/PassAnalysisSupport.h:242: AnalysisType& llvm::Pass::getAnalysisID(const void*, llvm::Function&) [with AnalysisType = llvm::ScalarEvolution]: Assertion `ResultPass && "Unable to find requested analysis info"'

Here is getAnalysisUsage() i am using, void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll(); AU.addRequired<DominatorTree>(); } and then I use it as, bool ptrTest::runOnModule(Module &M) { DominatorTree &DT = getAnalysis<DominatorTree>(); ...... } John Criswell wrote: > ambika wrote: >> But this is already present in

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

The transformation is phased, so all occurrences of getAnalysis<DominatorTree>(Function) happen before any occurrence of getAnalysisID<FunctionPass>(&DemoteRegisterToMemoryID, Function). I

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

Hey all, We have been working on a pass that uses another pass to count loads and stores prior to performing its own instrumentation. The second pass adds the first as required via the usual getAnalysisUsage function. On one machine, it has been tested and proven to function correctly. On another machine, whenever the second pass is run, it consistently fails the assertion: opt:

Dear All, The attached code (which is a contrived test case) hits the following assertion: test: /home/vadve/criswell/src/llvm22/include/llvm/PassAnalysisSupport.h:226: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*, llvm::Function&) [with AnalysisType = Pass1]: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not "
