2018-10-23erts: Do contention adaptions during (updating) iterationsSverker Eriksson
Once an iteration key has been found, never fall back to first/last key in next/prev tree as trees may split or join under our feet. I.e we must always use previous key when searching for the next key.
2018-10-23erts: Optimize find_next/prev_from_pb_keySverker Eriksson
to not have to backtrack up on the stack.
2018-10-23erts: Add erts_debug feature 'ets_force_split'Sverker Eriksson
to easier generate a routing tree for test without having to spend cpu to provoke actual repeated lock conflicts.
2018-10-23erts: Implement ets:info(T, stats) for catreesSverker Eriksson
{RouteNodes, BaseNodes, MaxRouteTreeDepth}
2018-10-19erts: Remove dead tree merging codeSverker Eriksson
2018-10-19erts: Remove tree merging for print and foreach_offheapSverker Eriksson
2018-10-19erts: Remove tree merging for ets:slotSverker Eriksson
Brute force solution will always iterate tree from slot 0 and forward. ToDo1: Yield. ToDo2: Maybe optimize by caching AVL tree size in each base node.
2018-10-19erts: Remove tree merging for ets:first,last,next,prevSverker Eriksson
2018-10-19erts: Remove tree merging for ets:select*Sverker Eriksson
2018-10-19erts: Add table type assertions for static stack accessSverker Eriksson
DbTableCATree has no static stack.
2018-10-19erts: Refactor ets:select* bound key lookupSverker Eriksson
Move lookup from analyze_pattern to callers.

2018-10-03erts: Refactor out DbRouteKey structSverker Eriksson
to not abuse DbTerm.
2018-10-03erts: Remove dead code in erl_db_catreeSverker Eriksson
'parent' is route node and 'neighbor' is base node, they can never be equal. 'neighbor_parent' has already been set correctly for all cases.
2018-10-03erts: Fix bug in erl_db_catreeSverker Eriksson
Search stack must be cleared before retry.
2018-10-03erts: Remove "dynamic" lock order supportSverker Eriksson
2018-10-03erts: Add lock order check for route nodesSverker Eriksson
Lock order is reverse tree depth, from leafs toward root. This solution may eventually fail if running too long as route nodes do not increase their 'lc_order' in a join operation when they move up in the tree. But who runs a VM with lock-checker for such a long time?
2018-10-03erts: Add lock order check of erl_db_catree base nodesSverker Eriksson
Lock order is key term order, so each base node needs its own key if lock check is enabled.

2018-10-03erts: Add some ERTS_RESTRICT pointersSverker Eriksson
2018-10-03erts: Do some refactoring in erl_db_catree.cSverker Eriksson
Fewer variables with shorter names and prefer DbTableCATree over DbTableCommon.
2018-10-03erts: Improve deallocation of CATree nodesSverker Eriksson
Update table memory stats before scheduling free to not be dependent on deallocation order with main table struct.

2018-09-28Rewrite BSM optimizations in the new SSA-based intermediate formatJohn Högberg
This commit improves the bit-syntax match optimization pass, leveraging the new SSA intermediate format to perform much more aggressive optimizations. Some highlights: * Watch contexts can be reused even after being passed to a function or being used in a try block. * Sub-binaries are no longer eagerly extracted, making it far easier to keep "happy paths" free from binary creation. * Trivial wrapper functions no longer disable context reuse.

2018-09-25erts: Remove unnecessary NIF argc testsSverker Eriksson
It's impossible to call NIF with wrong argc from Erlang and thus pointless to throw badarg.
2018-09-24Support using match contexts from Y registersJohn Högberg
The upcoming beam_ssa_bsm pass allows match contexts to be used across function calls that take said context as an argument, which means it's fairly common for them to end up in Y registers.
