Your question isn't clear; please restate what specifically isn't working. -Eli On Wed, Aug 14, 2013 at 11:57 AM, Rasha Omar <rasha.sala7 at gmail.com> wrote: > or like this > > %cmp4 = icmp eq i32 %rem, 0 > > br i1 %cmp4, label %if.then5, label %if.else7 > > > On 14 August 2013 20:08, Rasha Omar <rasha.sala7 at gmail.com> wrote: > >> Hi

How could BranchInst be used to insert new branch between two basic blocks to get result like this example: br label %if.else br label %if.then br i1 %cmp1, label %if.then, label %if.else Thanks for your help On 14 August 2013 21:36, Eli Friedman <eli.friedman at gmail.com> wrote: > Your question isn't clear; please restate what specifically isn't working. > > -Eli

Hi All, How could I use BranchInst to implement for example br label %if.else7 br label %if.then5 br i1 %cmp4, label %if.then5, label %if.else7 I can use BranchInst for only one instruction but how could I compare between two branches Thanks -- * Rasha Salah Omar Msc Student at E-JUST Demonestrator at Faculty of Computers and Informatics Benha University* *

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

But I don't want to map only basic blocks, I need too to map the edges "the whole CFG of the function" Save the CFG of the function in another memory address and call it for example orgCFG and change the CFG by referencing to the orgCFG Thank you for help and patience On 6 June 2013 10:59, Alexandru Ionut Diaconescu < alexandruionutdiaconescu at gmail.com> wrote: > I

I don't use a function for do the mapping, it may be MapValue(). If it does not work, alias an int identifier for each basic block. Be aware because basic block cannot have the same name (getName) in the same function, but they might have the same name being in different functions. Therefore, take into account the function name as well. Good luck On Thu, Jun 6, 2013 at 10:55 AM, Rasha Omar

Map every basic block from the CFG to a set of integers. The successors from the CFG can be used to make the edges in your simplified graph. The pair (Callee,Caller) can link the CFG-s between them in a larger CFG-like.

What do you mean by mapping to integers?

Hi All, Hope this question finds you I typed this command lli Main.ll Mod.ll to execute program in Mod.ll that contains three functions and the main function is in Main.ll but I've got the following error LLVM ERROR: Program used external function 'foo' which could not be resolved! Thanks in advance -- * Rasha Salah Omar Msc Student at E-JUST Demonestrator at

I have Function Function* F; and one of its basic blocks BB I want to insert this BB into a new function without remove it from the original according that BList is the list of the basic blocks of the newFunction BList.insert(BB); but I don't want to call BB->removeFromParent(); and without this method it give me error that BB is already in a container is there another function that get

Hi All, I need to call global variable by its name from the following code for(Function::iterator i=F->begin();i!=F->end();++i) { BasicBlock*Bb =&*i; GlobalVariable* GV = new GlobalVariable(type,false, F->getLinkage(),0, "F$"+Bb->getName()); GV->setInitializer(Constant::getNullValue (typ)); GList.push_back(GV); } Could I solve that by

Hi, Is changing the successors for each basic blocks means by default that the Terminator Instruction will be changed or this is another problem should be solved? If case 2 please tell me how to change it according to the new successors?

I think I understood that, but what I mean is what is the function responsible to do mapping is it MapValue() in ValueMapper.h?

Does cloning copies the function with its address or it constructs a new address to the new function? Is this real copying for the CFG or just opaque one to do some work? If it's not real copying, please I need a method that can help me in copying the function in another with new pointer to another address. Please I need answer urgent Thanks On 29 May 2013 10:14, Rasha Omar <rasha.sala7

Hi All, I need to remove successors from every basic block to insert new ones I tried this code, but it doesn't work void RemoveSuccessor(TerminatorInst *TI, unsigned SuccNum) { assert(SuccNum < TI->getNumSuccessors() && "Trying to remove a nonexistant successor!"); // If our old successor block contains any PHI nodes, remove the entry in the //
