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.

Rewrite BSM optimizations in the new SSA-based intermediate format
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.

* Make connection_id part of the distribution handle as {ConnId, DistEntry} in order for BIFs to verify correct connection. * Make distribution handle opaque to net_kernel. * Remove some unsafe lockless reads of DistEntry.flags * Change state ERTS_DE_STATE_EXITING to be more of an internal state that prevents erts from enqueue, encode or schedule new data to be sent. Otherwise it should behave like ERTS_DE_STATE_CONNECTED.

2018-09-13Improve trapping in lists:reverse/2John Högberg
If the process had more free space than reductions it could run a lot longer than it was supposed to. It didn't honor the number of reductions going in either, nor did it bump reductions when returning its result or erroring out. This commit also removes this function from a work function in scheduler_SUITE as it's extremely sensitive to the number of reductions spent in the test, causing equal_and_high_with_part_time_max to fail on some machines.
2018-09-13Fix unsafe use of lists:reverse/1John Högberg
We said reverse/2 but used reverse/1 which is unsafe to use in preloaded modules. This didn't have any effect in practice as the affected functions weren't used before the code server was started, but it's still an error.
