Hash values

abergel
Hi!

Alejandro and I are working on a new profiling technique to identify redundant objects.

We’ve heard there are some effort on increasing the range of identity hash values. Currently, it goes up to 4096, which is not much. Can someone tell us about this?

Also, I discovered that -100 hash = -100. Does this make sense?

Cheers,
Alexandre

Check the spur format on clement's blog. If I remember we will have 12 bits for hashes soon.
