[llvm-dev] how to add createLowerSwitchPass to PassManager object?

[Taher via llvm-dev]

My pass crashes on the callsite of runOnFunction() as it calls GetAnalysis
to LazyValue internally.

FunctionPass* lower = createLowerSwitchPass();
lower->runOnFunction(F);

The crash log says: *Assertion failed: (Resolver && "Pass has not been
inserted into a PassManager object!")*

How do I get the PassManager object to add LowerSwitchPass? I can't happen
to find the object anywhere. Can the legacy pass manager run lower passes
in llvm14? Alternatively, is there another method I can use to create
LowerSwitchPass with the new PassManager?
