2019-04-12crash dump: Fix printing of "OldBinVHeap unused"Björn Gustavsson
During a garbage collection, there could have been an overflow in the old virtual heap.

Make sure that the instruction pointer is correct for a garbing process in a crash dump.

Wait a little after to make sure that fun holding process to complete its termination.
2019-04-12Remove redundant rule from EmakefileBjörn Gustavsson
According to the comment, this rule was only needed when communication with R7B nodes was supported.
2019-04-12Turn off more optimizations for no_opt modulesBjörn Gustavsson
With the new compiler in OTP 22, we have to use more options to turn off optimizations. This commit also skips the match_huge_int/1 test case in the unoptimized clone of the bs_match_int module because it could crash on memory-constrained computers.

2019-04-11distribution_SUITE: Remove irrelevant test atom_roundtrip_r16bBjörn Gustavsson
Communication with OTP R16b has not been supported for a while.
2019-04-11bs_construct_SUITE: Rename bs_add_overflow/1 to bs_append_overflow/1Björn Gustavsson
The test case tests that the bs_append instruction tests for overflow. Make that clear by renaming the test case. While at it, also add a few explicit garbage_collection/0 calls to make it more likeley to run successfully in tight memory situations.
2019-04-11bs_construct_SUITE: Remove troublesome test huge_binary/1Björn Gustavsson
This test case can fail for the wrong reason (swapping followed by a timetrap timeout). It is unlikely to fail because of a real bug.

2019-04-10erts: Revert creation 0 as wildcard in node_table_cmpSverker Eriksson
This is a partial revert of bf7c722bd3b30e04a56c2d369fd9f5501a8316d0. It does not make sense to treat 0 as a wild card in cmp function for the hash table as creation is part of the hash calculation.
2019-04-10Decentralized counters for ETS ordered_set with write_concurrencyKjell Winblad
Previously, all ETS tables used centralized counter variables to keep track of the number of items stored and the amount of memory consumed. These counters can cause scalability problems (especially on big NUMA systems). This commit adds an implementation of a decentralized counter and modifies the implementation of ETS so that ETS tables of type ordered_set with write_concurrency enabled use the decentralized counter. [Experiments][1] indicate that this change substantially improves the scalability of ETS ordered_set tables with write_concurrency enabled in scenarios with frequent `ets:insert/2` and `ets:delete/2` calls. The new counter is implemented in the module erts_flxctr (`erts_flxctr.h` and `erts_flxctr.c`). The module has the suffix flxctr as it contains the implementation of a flexible counter (i.e., counter instances can be configured to be either centralized or decentralized). Counters that are configured to be centralized are implemented with a single counter variable which is modified with atomic operations. Decentralized counters are spread over several cache lines (how many can be configured with the parameter `+dcg`). The scheduler threads are mapped to cache lines so that there is no single point of contention when decentralized counters are updated. The thread progress functionality of the Erlang VM is utilized to implement support for linearizable snapshots of decentralized counters. The snapshot functionality is used by the `ets:info/1` and `ets:info/2` functions. [1]: http://winsh.me/ets_catree_benchmark/flxctr_res.html
