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

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

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

What do you mean by mapping to integers?

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.

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

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* *

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

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.

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

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

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

1- I need the first example. 2- I set the Address uninitialized according to the documentation " Setting the name on the Value automatically updates the module's symbol table" from Value.h source code 3- I'm not sure about "select" instruction, you mean that the address is the new destination (basic block)that will be added Thanks On 23 July 2013 16:38, Tim Northover

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,

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?
