Maybe:
/* Records whether we still have the option of vectorizing this loop using
partially-populated vectors; in other words, whether it is still possible
for one iteration of the vector loop to handle fewer than VF scalars. */
“partial vectorization” sounds more like some parts of the loop would
remain scalar code (which would potentially be useful too).
OK with that change, thanks.
