Hi, For the following code const Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type, 0, "flag", Bb); Bb->getInstList().push_back(newInst); It gives me the error " error: no matching constructor for initialization of 'llvm::AllocaInst' AllocaInst* newInst = new

Hi Silky, Sorry for the slow reply. You probably already fixed this, but just in case I'll reply anyway.

Hi Alastair, Thank you so much for the information on the tools. Actually, I need to analyze which sections of code are prone to misses and mis predicts, and would have to eventually instrument the code. I was able to instrument and call an external function, but faced an issue while passing an argument to the function. I am following EdgeProfiling.cpp but couldn't figure out the problem.

Thank you for your help I tried Instruction* p=&( Bb->front()); Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", p); that works well but I need to store the value of the variable too. What's the method that could be used to store specific value?? On 30 July 2013 16:01, John Criswell

Hi, I need to insert new instruction into every basic block like x=1 or while loop I tried this code, but it doesn't work Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", Bb); Bb->getInstList().push_back(newInst); the error: void llvm::SymbolTableListTraits<llvm::Instruction,

Thank you for your help I found the problem, as hook() is a no paramter function,so for(Function::arg_iterator i = hook->arg_begin(), e = hook->arg_end(); i != e; ++i) { Args.push_back(i); /////////////Wong } we can add a call by Instruction *newInst = CallInst::Create(hook,

Hi, I'm gonna try to give some feedback, but I have only been working with LLVM for a few days, so don't take what I'm saying without verifying :-) > BasicBlock *ProgSlicer::CloneBasicBlock(const BasicBlock *BB, > DenseMap<const Value*, Value*> &ValueMap, > const char *NameSuffix, Function *F) { > > BasicBlock

Hi all, I am trying to write a pass where i am creating a clone of a function (the only difference being, the new function returns void , instead of any value). I am creating a new Function Type with a void return type (rest being the same as original function), and using this i am creating a new function body. Then, i clone the body of the old function into new function, but when ever i

Hi, I am working on a project with LLVM. What I need to do is to generate/insert some dummy/dead basic blocls which never have chance to be executed and put some instructions in those dummy/dead basic blocks. So far, the dummy/dead BB insertion is done. I am trying insert instructions in those dummy/dead BB. Actually, I can insert the legal instructions to dummy/dead BB, however, I really want

Try : INITIALIZE a1 if you didnt. if (cpProf EXISTS){ CallInst* newInst = CallInst::Create(cpProf,a1,""); if (BB->getTerminator() && CI) BB->getInstList().insert((Instruction*)CI, newInst); On Tue, Mar 5, 2013 at 1:04 PM, Anshul Garg <gargaa24 at gmail.com> wrote: > CallInst* newInst = CallInst::Create(cpProf,a1,""); >

I'm not sure I understand. This code: Instruction *NewInst = II->clone(); ..

Hi , I am trying to clone a BasicBlock. I want both to co-exist and I have introduced a conditional branch to the original or the cloned BB. I tried mapping the original instruction and the clone as below : Instruction *NewInst = II->clone(); if (II->hasName()) NewInst->setName(II->getName()); NewBB->getInstList().push_back(NewInst); ValueMap[II] =

Well, it does so to implement Arnold and Ryder style profiling. I can send you a copy of that if you want (I hope to

Hello Andrew , Yes , I have missed the phi node since my paths merge together. I'll try this out. I am implementing a timer based profiling scheme and hope your code will be useful for me.

Hi, Nick, thanks for the reply. I still have a problem: I only need to "clone" an Instruction, changing its type. That is, I would like to keep all characteristics of the old Instruction and create a new one only with a different type. I am trying create a new Instruction thus: %3 = add nsw i32 %1, %2 ; <i16> [#uses=2] //Old Instruction Value* Op0 = I->getOperand(0); Value*

Hi Matthijs, Thanks for giving some code so we can discuss this in more concrete detail. In terms of the information we need, I think you have it right. We just need a description of how the different address spaces relate and I don't see much of an issue with how you implemented to InstructionCombining. As you also mentioned, I don't like that we pass a reference to
