similar to: [LLVMdev] construct new function

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

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 Rasha, First, you should not erase that cloned function XD the idea is that your pass should create that new function, add it to a module (that could be the same one where the original function is, or another one that you could be creating if that is the case), and then just let it be: the pass manager should identify this new function (after your pass returned) and all the other analysis and

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

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 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

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.

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, 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* *

Why you don't map the basic blocks to integers and apply algorithms on the integer graph? And construct your new CFG.

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

How could I keep the function CFG in another memory space. I want to be able to change one of the old CFG , but keeping the original one in another space.

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

Dear All, I need your help urgently I have to copy the CFG of each function using CloneFunction or CloneFunctionInto. After I made the copy function. Print the basic blocks then get this error : While deleting: i32 % Use still stuck around after Def is destroyed: %mul2_ = mul nsw i32 %6, 3 Use still stuck around after Def is destroyed: store i32 3, i32* %x_, align 4 opt: Value.cpp:75: virtual

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
