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.

This allow languages such as Elixir and LFE to attach
extra chunks to the .beam file without having to parse
the beam file after compilation.
This commit also cleans up the interface to beam_asm,
allowing chunks to be passed from the compiler without
a need to change beam_asm API on every new chunk.

Add the option 'deterministic' to make it easier to
achieve reproducible builds.
This option omits the {options,...} and {source,...} tuples in
M:module_info(compile), because those options may contain absolute
paths.
The author of ERL-310 suggested that only compiler options that
may contain absolute paths (such as {i,...}) should be excluded. But I
find it confusing to keep only some options.
Alternatives considered: Always omitting this information. Since this
information has been available for a long time, that would probably
break some workflows. As an example that some people care about
{source,...}, 2d785c07fbf9 made it possible to give a compiler option
to set {source,...}.

The deprecation of the built-in types dict/0 and so on had as
side-effect that it was impossible to switch to dict:dict/2 and so on
without getting warnings either in the the previous release (R16B) or
the current one (17.0).
By including the attribute
-compile(nowarn_deprecated_type).
in an Erlang source file warnings about deprecated types can be
avoided in 17.0.
The option can also be given as a compiler flag:
erlc +nowarn_deprecated_type file.erl

OTP-11682

erlc is wired to treat *.core files as core and build them as
compile:file(File, [from_core]), but this is not documented. There's
also an udocumented compile:file/2 option called 'from_core'. This has
been in place and in use for a long time. Therefore, it should be
supported officially.
To fix that, make the following changes:
* document erlc handling of *.core files
* document 'from_core'
|
|
erlc is wired to treat *.S files as assembler and build them as
compile:file(File, [from_asm]), but this is not documented. There's also
a documented compile:file/2 option called 'asm' (mapping to 'from_asm'),
but the wording discourages its use. All of this has been in place and
in use for a long time. Therefore, it should be supported officially.
To fix that, make the following changes:
* document erlc handling of *.core files
* un-document 'asm' and document 'from_asm' instead
* deprecate 'asm'
While at it, fix a minor typo in the test suite.

This patch introduces the no_auto_import attribute:
-compile(no_auto_import).
Useful for code generation tools that always use the
qualified function names and want to avoid the auto
imported functions clashing with local ones.
Implementation wise, we chose to have a special flag
'all' to avoid doing many set lookups when checking for
suppression.

Change encoding of troublesome notes.xml files to utf-8

* maint:
compiler: Conform returned errors to the documented format

Most notes.xml files will be updated in every release and cause
the kind of the problems described in the previous commit.

ErrorInfo is documented to be:
{ErrorLine,Module,ErrorDescriptor}
but for some errors with line numbers it would look like:
{Module,ErrorDescriptor}
Ensure that all ErrorInfo tuples have three elements. Use 'none'
instead of a line number:
{none,Module,ErrorDescriptor}
There already are errors that return 'none' when no line number is
available, but that convention was not documented. Mention it in the
documentation.
Also make sure that the compiler will not print 'none' as a line
number in error messages (if the 'report_errors' option is given) as
that looks stupid. That is, when attempting to compile a non-existing
module, the error message should be:
non-existing.erl: no such file or directory
and not:
non-existing.erl:none: no such file or directory
