I'd think so, but it probably requires a new profiler that counts for how often 0 <= A <= B for every "A % B". Just profiling the range of values might be misleading (because A <= N and B <= M and N <= M doesn't imply that A <= B often holds). But it would possibly be an interesting experiment already to do such transformation generally (without profiling) and see what it gives on some benchmarks. Just to get a feel what's on the plate. > IIRC value-prof > handles constant divmod but not ranges for modulo operations. Ciao, Michael.
