- New representation of refs in R9, see erl_term.h
-
- In the first data word, only the usual 18 bits are used. Ordinarily,
- in "long refs" all words are used (in other words, practically never
- wrap around), but for compatibility with older nodes, "short refs"
- exist. Short refs come into being by being converted from the old
- external format for refs (tag REFERENCE_EXT). Short refs are
- converted back to the old external format.
-
- When converting a long ref to the external format in the case of
- preparing for sending to an older node, the ref is truncated by only
- using the first word (with 18 significant bits), and using the old tag
- REFERENCE_EXT.
-
- When comparing refs or different size, only the parts up to the length
- of the shorter operand are used. This has the desirable effect that a
- long ref sent to an old node and back will be treated as equal to
- the original, although some of the bits have been lost.
-
- The hash value for a ref always considers only the first word, since
- in the above scenario, the original and the copy should have the same
- hash value.
