2017-02-28erts: Convert small sub-binaries to heap-binariesBjörn-Egil Dahlberg
In many cases sub-binaries costs more memory than converting them to heap-binaries. Sub-binaries also has a hidden cost of pinning larger binaries in memory. By converting binaries this cost is reduced. Byte aligned sub-binaries upto 24 bytes (64-bit) or 12 bytes (32-bit) are converted.

A magic destructor can return 0 and thereby take control and prolong the lifetime of a magic binary.

1> round(6209607916799025.0). 6209607916799026 Problem: Adding/subtracting 0.5 and large double floats between (1 bsl 52) and (1 bsl 53) does not give reliable results. Solution: Use round() function in math.h.

2017-02-06Implement magic referencesRickard Green
Magic references are *intentionally* indistinguishable from ordinary references for the Erlang software. Magic references do not change the language, and are intended as a pure runtime internal optimization. An ordinary reference is typically used as a key in some table. A magic reference has a direct pointer to a reference counted magic binary. This makes it possible to implement various things without having to do lookups in a table, but instead access the data directly. Besides very fast lookups this can also improve scalability by removing a potentially contended table. A couple of examples of planned future usage of magic references are ETS table identifiers, and BIF timer identifiers. Besides future optimizations using magic references it should also be possible to replace the exposed magic binary cludge with magic references. That is, magic binaries that are exposed as empty binaries to the Erlang software.
