Thanks. Calling getAnalysis with a Function* argument and removing const from iterator solved the problem. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20080305/faff1821/attachment.html>

Hello, I have two passes, A and B. A is a function pass. B is a module pass. Each uses their getAnalysisUsage() method to .addRequired() several passes, and each .setPreserveAll()s. **Pass B requires pass A**. But, when I call getAnalysis<A> from within B, it exclaims: Assertion `ResultPass && "getAnalysis*() called on an analysis that was not "

Hello, I'd appreciate it if anyone can tell me what the error message means and point out what I am doing wrong. Thank you. I am trying to use the result of the DominatorTree analysis in my ModulePass class as explained in the section "Writing an LLVM Pass". http://llvm.org/docs/WritingAnLLVMPass.html#interaction I called the method "addRequired<DominatorTree>()"

I'm having trouble with using getAnalysis() to access the results of one pass from within another. I require the pass to be previously executed as follows: void MyPass::getAnalysisUsage(AnalysisUsage &Info) const { Info.addRequired<TDDataStructures>(); } Then I try to use it as follows: bool MyPass::doInitialization(Module &M) { TDDataStructures &dsgraph =

I’m debugging SAFECode source code files, and in AllocatorInfo.cpp, in the function getObjectSize(Value* V), the function getAnalysis<DataLayout>() is called. I’ve run into this problem before, and the first time I saw it, my employer recommended I use M.getDataLayout() instead, where M was a reference to a Module. However, in getObjectSize(Value* V), there is no Module reference in the

Sure. I've attached the code for the test pass I wrote, as well as the code and bitcode for the testcase I'm running. All the functionality has been stripped out of the pass, and the pass compiles without a problem, but the error appears when the pass is run.

Hi! I am trying to extend the native AliasAnalysis of LLVM to use an external analysis pass. Doing this with the legacy pass manager works fine through calling addRequired() in the getAnalysisUsage and getAnalysis() in function runOnFunction(). In the new pass manager, I haven't found a similar way of doing this. When running opt with -O3, I encounter the following error: >Assertion

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 &&

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, 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*,
