2019-07-02erts: Improve hash shrinkingSverker Eriksson
* Release is_resizing as soon as possible to improve shrink concurrency. - Do join of buckets after release, but with kept WLOCK_HASH. - Do deallocations of seg and segtab after release of both is_resizing and WLOCK_HASH. * Do lazy initialization of buckets in extended segments. - Mark inactive buckets in DEBUG.

qsort expects the comparison function to return an int; returning an `Sint` may yield nonsensical results.
2019-07-01erts: Fix integer overflow in list subtractionJohn Högberg
CMP_TERM returned an `Sint`, which overflowed the `int` used in erl_rbtree for storing the comparison, causing list subtraction to behave strangely.

2019-06-27erts: Cleanup start of all erts threads to ABORT when failingLukas Larsson
Before this change erts used to crash dump and then abort, but a crash dump is not really usefull at this point and it caused all sort of lock problems when crash dumping that early in the system boot, so now it is changed to only dump core instead. Also in the process I cleaned up some the code so that it does not to a lot of things that are not needed.

* kjell/stdlib/ets_ordered_set_slow_react/OTP-15906: ETS ordered_set: Improvements to the CA tree implementation
2019-06-18ETS ordered_set: Improvements to the CA tree implementationKjell Winblad
This commit only affects the implementation of ETS `ordered_set` tables with the `write_concurrency` option enabled. Such tables are implemented with a data structure that is called the contention adapting search tree (CA tree). This commit introduces the following changes: * This commit causes a join to be triggered in one randomly selected base node in about one of 1000 read unlock calls for base node locks. No such joins happened before this commit. Before this commit, operations that only acquired looks in read-mode never triggered any contention adaptation. Therefore, the CA tree could get stuck in a sub-optimal state in certain scenarios. This could happen, for example, when a CA tree is first populated with parallel inserts (which will cause splits of base nodes) and then only read-only operations are applied to the data structure. Benchmark results from the `ets_SUITE:lookup_catree_par_vs_seq_init_benchmark/0` benchmark function (which is included in this commit) shows that this change can improve the throughput of the CA tree in the scenario described above. * Read-only operations will now also increase values of statistics counters when they detect that they need to wait for other operations. Only write operation changed statistics counters before this commit. This improves the statistics that the adaptation heuristics is based on. * Additionally, this commit adds an upper and lower limit to the contention statistics variables in the base nodes. Such limits did not exist before this commit. This should, for example, make the CA tree more responsive to contention after long periods of low contention.

2019-06-14Support sharing of fun entries in the runtime systemBjörn Gustavsson
Before OTP 23, there had to be a one-to-one correspodence between `make_fun2` instructions and fun entries. In the OTP 23 runtime system, start keying the fun entries with the explicit ("new") index included in the fun entry. That will allow multiple `make_fun2` instructions to refer to the same entry in the fun table. This change is safe for code compiled by OTP R15B or later, because the old and new indices are identical. The loader will refuse to load code where the old and new indices are not equal unless the code is known to be compiled with an OTP 23 compiler.

2019-06-14Stop supporting decoding of old funs in the external term formatBjörn Gustavsson
The new external format for funs (NEW_FUN_EXT) was introduced in OTP R8 along with the `make_fun2` instruction. Therefore, it should be safe to stop decoding the old FUN_EXT tag.
