[LLVMdev] Adding instructions to loop
I am attempting to add instructions before and after all loops. To do

return;
}
The function added is trivial:
void printloopbegin() {
fprintf (stderr,"Loop Beginning\n");
}
The function is called from runOnFunction() as follows:
PrintLoopBegin = F.getParent()->ge...
