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.

2017-02-06Add binary overhead for magic ref/binariesRickard Green
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.

2017-02-06Atomic reference count of binaries also in non-SMPRickard Green
NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc()
