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

<br>
Create a store instruction (StoreInst) that stores the desired value
into the memory created by the alloca instruction.<br>

<div>Hi,<br>
</div>
<div>I need to insert new instruction into every
basic block like x=1<br>
</div>
<div>or while loop<br>

<div>I tried this code, but it doesn't work<br>
<br>
Type * Int32Type =
IntegerType::getInt32Ty(getGlobalContext());<br>
AllocaInst* newInst = new
AllocaInst(Int32Type,"flag", Bb);<br>
Bb->getInstList().push_back(newInst);<br>
</div>

The problem is that you've inserted the AllocaInst into
the basic block via the AllocaInst constructor (note the
Bb at the end of the line with new AllocaInst). You then
attempt to insert the AllocaInst into the BasicBlock Bb a
second time with the last line. Note that the assertion
is telling you that you're inserting the alloca
instruction twice.<br>
<br>
Remove the last line, and it should fix your problem.<br>
