efriedma added a comment. Are you saying that it's faster to use clasta targeting a float register, then move the result to an integer register, rather than use the integer form directly? Or is the issue just that we want to split the operations in case we can simplify the resulting bitcast?
Do we expect SelectionDAG to combine a clasta+bitcast to a single instruction? Do we have test coverage for that?
