2019-08-12erts: Fix crash in instrument:allocations/0-1John Högberg
The current carrier list was read when the allocator wasn't locked, crashing the emulator if a block scan raced with a carrier allocation.

2019-08-09erts: Create heap binaries in bs_get_binary2John Högberg
ErlSubBin is a large struct that often dwarfs the region of memory it points at, and it's common for them to refer to a ProcBin which must be kept around as long as the SubBin lives, using up even more heap space and keeping the referenced binary alive regardless of how small the sub-binary is.
2019-08-09erts: Remove size check in bs_start_matchJohn Högberg
The size check is redundant now that all binaries are guaranteed to be small enough that their size in bits fits into a word.
2019-08-09erts: Disallow binaries whose size in bits exceeds UWORD_MAXJohn Högberg
These have never worked in binary matching (including sub-binaries extracted from them) so it's hard to justify their existence. They also make a future migration of binary sizes from bytes to bits problematic, so we may as well change it ahead of time. This is potentially incompatible on 32-bit platforms where a NIF or driver could allocate 512MB+ binaries, but allocations that large should be expected to fail anyway.

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.
