Using predicated execution ([\#2b1]), one does not have to create a
prologue or an epilogue when trying to execute a loop, and apparently
also benefits from a large performance increase by using predicated
execution. This is because each instruction in the kernel can be
predicated in such a way that the pipeline gets filled correctly, and
then in such a way so that it gets drained correctly.
