Hi,
I would propose to first check if the trip count is calculated
correctly. I would do this with opt

[LLVMdev] Wrong AliasAnalysis::getModRefInfo result
...}
int main()
{
int a[10];
int b[10];
for(int i=0; i<10; i++)
a[i] = i;
foo(a,b);
return 0;
}
Obviously, for "foo", it only reads from array "a" and only writes to array
"b".
The LLVM pass:
virtual bool runOnFunction(Function &F) {
++HelloCounter;
errs() << "Hello: ";
errs().write_escaped(F.getName()) << '\n';
AliasAnalysis &AA = getAnalysis<AliasAnalysis>();
for (inst_iterator I = inst_begin(F), E = inst_end(F); I != E; ++I) {
Instruction *Inst = &*I;

Opt plugin linkage
...other follow-up, seems like ExecutionEngine is still not usable without editing CMakeLists, on my setup I had to edit CMakeLists.txt as well to get the example working.
Below is the modifications I made:
Modified Hello.cpp for testing:
```
bool runOnFunction(Function &F) override {
++HelloCounter;
std::string errStr;
EngineBuilder eb;
eb.setErrorStr(&errStr);
eb.setEngineKind(EngineKind::Kind::JIT);
ExecutionEngine* ee=eb.create();
errs()<<"ExecutionEngine:"<<ee<<" Error:"<<errStr<<"\n";...

Opt plugin linkage
Hey:
I spent sometime debugging this, it seems like editing ``llvm/tools/opt.cpp`` and move ``cl::ParseCommandLineOptions(argc, argv,
"llvm .bc -> .bc modular optimizer and analysis printer\n");`` to the beginning of main() solved it for me. I'm not sure if this is a bug on LLVM side
