Evgeny Stupachenko 9d35c64dc2 The patch fixes PR27392. ... Summary: It is incorrect to compare TripCount (which is BECount + 1) with extraiters (or Count) to check if we should enter unrolled loop or not, because TripCount can potentially overflow (when BECount is max unsigned integer). While comparing BECount with (Count - 1) is overflow safe and therefore correct.
