There isn't any, so typically it's other.

Don't forget llvmpipe is mostly useful for running simple things, like for
instance desktop compositing, where the shaders might not even have any control
flow. I agree it should help with more complex shaders, but optimizing for that
just wasn't that important - developer time isn't unlimited. But feel free to
give it a try :-).
