similar to: [LLVMdev] pass registration

hello sir i have created LoopPass but now i am facing problem in Registering that pass. I read all the documents & followed the procedure but its giving error. Can you tell me what is the right way to register a pass. I am getting errors like char::ID=0 "ID" is not in the scope {anonymous::PrintLoopPass something like} please help me -------------- next part -------------- An

i am beginner in llvm compiler framework. As i want to create loop pass i went through all the procedure for creating new pass. I did all the steps u mentioned but when i copied the content of makefile(for hello pass) from ur website to my makefile its not working properly. My makefile is like this : # Makefile for hello pass # Path to top level of LLVM hierarchyLEVEL = ../../.. # Name of the

Hi, As you said i downloaded arm toolchain from codesourcery(2009q3 with gcc 4.4.1 version).. if i use this toolchain i am getting the following error.. make[2]: Entering directory `/home/prasanth/LLVM_ARM/llvm-with-armgcc441/llvm-obj/lib/Analysis' llvm[2]: Compiling LoopPass.cpp for Release build if arm-none-linux-gnueabi-g++ -I/home/prasanth/LLVM_ARM/llvm-with-armgcc433/llvm/include

Hi, I am trying to compile the Hello World pass (described at http://llvm.org/docs/WritingAnLLVMPass.html#basiccode) in an LLVM Project and I get an error, 'no match for ‘operator<<’ at line llvm::cerr << "*Hello: *" << F.getName() << "\n"; But when I looked up in the LLVM API Documentation, I think "<<" operator is not overloaded

Hi all, I have a code with three passes (one loop pass and two module passes) and my own pass manager. If I schedule the loop pass between the others, my code segfaults. Is there any explanation why loop passes cannot be scheduled between two module passes? Perhaps I misunderstood the behaviour of pass managers. I paste here my "usage" information: int main(...){ Module m = ...

I'm wondering if the documentation for LoopPass ( http://llvm.org/docs/WritingAnLLVMPass.html#LoopPass) is misleading or incorrect (or if I'm just missing something.) The documentation states: "The doFinalization method ... is called when the pass framework has finished calling runOnLoop<http://llvm.org/docs/WritingAnLLVMPass.html#runOnLoop> for every loop in the program being

That way you should get an assert failure with a helpful message rather than a crash. Is there any explanation why loop passes cannot

Hi Edvard, _ZTIN4llvm8LoopPassE is "typeinfo for llvm::LoopPass". LLVM is built without typeinfo, so you will need to build your pass with -fno-rtti.

But is there a better way of getting the loops in a function than using LoopInfo? For some tasks it is necessary that we don't process the same loop twice. Doing that with LoopInfo requires the use of a flag.

Hello . I'm trying to implement LoopPass. Here is simple code :    class LoopParser: public llvm::LoopPass   {     public:       static char ID;     public:       virtual void getAnalysisUsage(llvm::AnalysisUsage &AU) const       {         AU.addRequiredID(llvm::LoopSimplifyID);         AU.addPreservedID(llvm::LoopSimplifyID);         AU.addRequired<llvm::LoopInfo>();       }

Hi, Lately LLVM has been adding -fno-rtti to most of the compiler. I have a pass which uses LoopPass and which inherits from FunctionPass and a class of my own. If I compile my code with ENABLE_RTTI=1, I can't dynamically load the shared object since it won't be able to find the symbol for LoopPass's typeinfo. undefined symbol: _ZTIN4llvm8LoopPassE $ c++filt _ZTIN4llvm8LoopPassE

LLVMers, I have a traversal plan which needs to visit certain types of Functions. For each instruction in such functions, I will need to know: 1. is it located inside a loop 2. if yes, what level of loop nest it is currently in. So on the highest level, it should be a FunctionPass. However, in order to identify loops and loop-nest levels, it should also be a LoopPass. Is there a reasonably
