[cfe-dev] Checking if function have been emitted

[Piotr Padlewski via cfe-dev]

Hi,
I would like to check if there is inline virtual function that was not
emitted.

I tried to do something like this based
on CodeGenModule::GetOrCreateLLVMFunction:

      StringRef Name = CGM.getMangledName(VFunction);
      auto *Entry = CGM.GetGlobalValue(Name);

      // If function doesn't exist or doesn't have a definition.
      if (!Entry || Entry->isDeclaration())
        return true;

But Entry->isDeclaration() returns True for functions that I would expect
to be emited.
What is the proper way of checking that?

Thanks for help!
Piotr


PS:
here is the patch that doesn't work, to get wider scope.
