Actually there are problems with the predicated forms of load: with them you can hoist over a branch, as shown in the paper, but you can’t hoist over the computation of the predicate. Spectre has prompted much internal discussion about an alternative that doesn’t require the predicate until retire (easy) and is still safe from Spectre-like attacks (real hard). NYF for now.
