erts: fix attempt to start timer when executing on dirty scheduler OTP-15446
2018-11-26erts: fix attempt to start timer when executing on dirty schedulerMaxim Fedorov
Since OTP R20, there is a possibility for MAJOR garbage collection to run on dirty scheduler. So DistEntry destructor is being called on dirty scheduler as well. This, in turn, leads to an attempt to schedule timer on a dirty scheduler too, which is impossible (and will assert on debug build, but does succeed for release build, creating an infinite busy loop, since aux work wakes scheduler up, but dirty scheduler cannot execute aus work). There is a similar method in erl_hl_timer, see erts_start_timer_callback.

net_kernel crashed due to invalid return from handle_info. Could only happen if erts_internal:new_connection fails due to non-atom Node or if Node is the own node name.

Enhance compiler optimizations
2018-11-21Sort move instructions on the Y registerBjörn Gustavsson
Sort sequences of `move` instructions on the Y register. When moving from X registers to Y registers, having the instructions sorted on Y registers give the loader more opportunities to use `move_window{3,4,5}` instructions. For examples, the following five instructions: move_xy x(2) y(0) move_xy x(1) y(1) move_xy x(0) y(2) move_xy x(5) y(3) move_xy x(4) y(4) can be replaced with: move_window5_xxxxxy x(2) x(1) x(0) x(5) x(4) y(0) When the Y registers are not ordered so that `move_window5` can be used, the loader would typically combine the first three moves to a `move3_xyxyxy` instruction and the last two moves to a `move2_par_xyxy` instruction. When moving from Y registers to X registers, sorting on the Y registers could potentially be more cache-friendly. It could also be worthwhile investigating a new `move_window` instruction in the BEAM interpreter that could move values from contiguous Y registers to X registers. Note that `scripts/diffable` can generate diffable dissambly files for the loaded BEAM code: $ scripts/diffable --dis 0 $ scripts/diffable --dis 1 $ diff -u 0 1

2018-11-21Fix inadvertently suppressed warning for unused variableBjörn Gustavsson
An external fun could inadvertently suppress warnings for unused variables, such as in this example: bug() -> BugVar = foo(), if true -> fun m:f/1 end. There would be no warning that `BugVar` was unused. The bug was introduced in ff432e262e652, which was the commit that extended external funs to allow variables. https://bugs.erlang.org/browse/ERL-762

2018-11-20Allow disabling retpoline in interpreter loopJohn Högberg
We only do this when the user has explicitly told us it's okay to partially disable mitigation (spectre-mitigation=incomplete). The macro is inert if it isn't.
2018-11-20Add a ./configure flag for spectre mitigationJohn Högberg
Note that the ERTS_NO_RETPOLINE macro introduced by this commit is completely inert unless spectre-mitigation is set to 'incomplete.' This includes when mitigation has been manually enabled through CFLAGS, so it should be impossible for it to unintentionally disable mitigation.
