Hi @rwestrel , may I ask you a question about this? From your comments, I see `short_scale` reports if a `ConvI2L` node is present since it's used to protect against overflow. Does this mean that `ConvI2L` at this point only appears in long counted loops? I ask this because in my knowledge array address computing in int loops also generates `ConvI2L` on 64-bit platforms.
