llvm dev - Apr 2011 - [LLVMdev] inserting a fucntion call at the end of basic bloc

hi all,

i would like insert a fucntion call at the end of each basic bloc
the fucntion i have defined and declared at the begining of the module
ie i have written a pass derived from a module pass
virtual bool runOnModule(Module & M){
// i declared the fucntion and defined it
for (Module::iterator a = M.begin(), b = M.end(); a != b;
          for (Function::iterator i = a->begin(), e = a->end(); i != e;
++i)
{

        //call the function
           }
}

}
i tried to see an example with the demo, i saw that it instead of calling
the function, it repeats all the instruction that are existing in the
function
Any help?

Hi Nabila,

you can't, because only terminators are allowed at the end of a basic block.
However you can try to insert the call before the terminator.

Turn off optimization in the demo (optimization level "None").

Ciao, Duncan.

Yes, i mean before the termininator,
My problem is how to call a method
suppose this fucntion
void A(int x)
{
  x=x+1;

}

should i define this function and declare it at the beginig of the module
and create for it a basic bloc?
and then how to call it before each basic bloc terminitor
