* dgud/erts/erlscript_name:
Rename argv[0] from beam to invoking program name
OTP-14381

No need for the xor-trick, to be order independent, as both
flatmaps and hashmaps have a constant key-value order internally.

Clear ethr_not_inited__ early (like on unix)
to not get assertion in ethr_tsd_key_create("stacklimit")

Fix assert in dbg_verify_empty_later_slots()

The macro previously named 'LOG2' is in fact computing the LSB (not the MSB)
of its input, and can only be used to compute log2(n) when n is is a power
of 2, that is, when its LSB is also its MSB.

Introduce new "Dbgi" chunk

* lukas/erts/list_to_port/OTP-14348:
erts: Add erlang:list_to_port/1 debug bif
erts: Auto-import port_to_list for consistency
erts: Polish off erlang:list_to_ref/1
|
|
|
|
Follow the same pattern as pid_to_list
|

The new Dbgi chunk returns data in the following format:
{debug_info_v1, Backend, Data}
This allows compilers to store the debug info in different
formats. In order to retrieve a particular format, for
instance, Erlang Abstract Format, one may invoke:
Backend:debug_info(erlang_v1, Module, Data, Opts)
Besides introducing the chunk above, this commit also:
* Changes beam_lib:chunk(Beam, [:abstract_code]) to
read from the new Dbgi chunk while keeping backwards
compatibility with old .beams
* Adds the {debug_info, {Backend, Data}} option to
compile:file/2 and friends that are stored in the
Dbgi chunk. This allows the debug info encryption
mechanism to work across compilers
* Improves dialyzer to work directly on Core Erlang,
allowing languages that do not have the Erlang
Abstract Format to be dialyzer as long as they emit
the new chunk and their backend implementation is
available
Backwards compatibility is kept across the board except
for those calling beam_lib:chunk(Beam, ["Abst"]), as the
old chunk is no longer available. Note however the "Abst"
chunk has always been optional.
Future OTP versions may remove parsing the "Abst" chunk
altogether from beam_lib once Erlang 19 and earlier is no
longer supported.
The current Dialyzer implementation still supports earlier
.beam files and such may also be removed in future versions.

Add smoke test for TypER
Add back TypEr to the main OTP repository

bind to device is needed to properly support VRF-Lite under
Linux (see [1] for details).

It turned out that the dependencies between Dialyzer
and TypEr makes it impractical to have TypEr in a
separate repository.
Add it back to the OTP repository, but put the Erlang
module 'typer' in the dialyzer application.

The previous code worked through luck because the memory
returned from erts_alloc was zero:ed and SCHED_NORMAL
is 0. But if you run with +Meamin that is not always the
case which is how this error was detected.

It is no longer possible to commuicate with R9B nodes.

Add re:version/0
OTP-14347

|
|
Minimum known timeout position is saved in bot far and near
wheel. This information is used to avoid scanning from current
position in the cases were we know the minimum timeout position.
|
|
|
|
Timer counters for ranges of slots in order to be able
to avoid inspecting large ranges of slots without timers.
|
|
The old single wheel implementation handled about 65 seconds. The
new dual wheel implementation handles more than 37 hours. The dual
wheels have also been shrunk compared to the single wheel, so the
total memory consumption for timer wheels have been cut in half.
