<pre>
    I have written a new pass for instrumentation using LLVM-15.0.0. The pass can be executed normally when using command like `clang -g -fpass-plugin=../xxPass.so`. Now I want to insert it into LLVM so default clang will output a instrumented binary without extra command args. But the instrumentation can not operate when Pass is inserted into LLVM.

The part of the code of the pass the cause the error is:

```cpp
...
IRBuilder<> builder(beginInst);
// call ptr @fopen(ptr @.str, ptr @.str.1)
// fileName, mode
ArrayRef<Value*> fopenArgs = {
        getStrConstant(fileName, builder), // icall_log.txt
        getStrConstant(mode, builder) // a
 };
errs() << "-----------------inserting fopen for log func names\n";
CallInst* fid = builder.CreateCall(fopenFunc, fopenArgs);
```

`builder.CreateCall` is where the error occur. When compiled into a plugin, the registration code is:

```cpp
PassPluginLibraryInfo getTraceLogCallBack() {
 const auto callback = [](PassBuilder &PB) {
 PB.registerPipelineEarlySimplificationEPCallback(
 [&](ModulePassManager &MPM, auto) {
 MPM.addPass(TraceLogPass());
                    return true;
 });
    };
    return {
            LLVM_PLUGIN_API_VERSION, "TraceLogPass", "v0.1", callback
    };
}

// This part is the new way of registering your pass
extern "C" ::llvm::PassPluginLibraryInfo LLVM_ATTRIBUTE_WEAK
llvmGetPassPluginInfo() {
    return getTraceLogCallBack();
}
```

When inserted into LLVM, I register it in [addSanitizers](https://github.com/llvm/llvm-project/blob/llvmorg-15.0.0/clang/lib/CodeGen/BackendUtil.cpp#L623) function like

```cpp
static void addSanitizers(const Triple &TargetTriple,
                          const CodeGenOptions &CodeGenOpts,
                          const LangOptions &LangOpts, PassBuilder &PB) {
  errs() << "start executing addSanitizer\n";
 PB.registerPipelineEarlySimplificationEPCallback(
 [&](ModulePassManager &MPM, OptimizationLevel Level) {
 MPM.addPass(TraceLogPass()); // MyPass
      });
 PB.registerOptimizerLastEPCallback([&](ModulePassManager &MPM,
...
```

The part of error trace is:

```

```

How should I register the pass in LLVM?
