Hello John,
I was following your procedures and I isolated the problem. The problem are
represented by the basic blocks with only one element.
for (Function::iterator II = F.begin(), EE = F.end(); II != EE; ++II, ++ii)
{
BasicBlock* BB=II;
if (BB->getTerminator())
{
Instruction* current = BB->getTerminator();
Instruction* previous;
errs()<<"AAA\n";
if(*current->getPrevNode()*)
{
errs()<<"BBB\n";
previous = current->getPrevNode();
ok=1;
}
if (ok){
errs()<<"CCC\n";
........
It does print AAA, but then I have the segfault. So when I am evaluating
the *current->getPrevNode() *condition, I got the segfault.
Do you know how can I solve this?
Thank you
Alex
