Comment at: llvm/lib/Target/AMDGPU/AMDGPUCtorDtorLowering.cpp:56
     ConstantArray *GA = dyn_cast<ConstantArray>(GV->getInitializer());
     if (!GA || GA->getNumOperands() == 0)
       return false;

Isn't this just being defensive about what type the initializer is? That seems wise to me, you also wouldn't need a dyn_cast otherwise.
