A lot of time spent on linting is due to eval_file_attribute/2
function that recursively traverses all the AST, annotating
the file name on the AST nodes. This traversal happens so
it is easier to add errors and warnings later on by simply
introspecting the node.
This patch changes eval_file_attribute/2 to only annotate
forms (i.e. attributes and functions) and rely on the #lint
record to keep the proper file information (which it already
did before this patch).
To summarize, both pre scan and pos scan will use the annotated
file attribute in forms, however form/2 already maintains the
proper file in #lint, which we pass around when retrieving the
location information.
After this patch, linting of a regular erlang module with 500LOC
became twice faster when measured with eprof.

Compilation on Erlang 18.0-rc2 is about 10% slower than in Erlang 17.
After some debugging, we have noticed that linting is on average 30%
to 50% slower being the main responsible for the performance reduction.
Later profiling revealed is_filename/1 to be the biggest culprit. The change
in this commit brings compilation times to about the same times as Erlang 17.
Note this commit doesn't change the compiler behaviour compared to Erlang
17 because we didn't sanity check the value given to the file annotation in the
past. I would say checking the filename is not worth it if it means compilation
becomes 10% slower on average. After all, there are many places in the
compiler where it will fail if we give it a malformed tree, I wouldn't then special
case file annotation.

When compiling parser files, because they rely heavily
on inline annotations, retrieving the nowarn_bif_clash
information from the compiler options is expensive.
This patch stores nowarn_bif_clash in the lint record.
By using erlc +'{eprof,lint_module}' when compiling the
erlang parser, we noticed the time spent on
nowarn_function/2 reduced from 30% to 0.01%.

This commit adds a new function, ssl:connection_information/[1,2]
to retrive the connection information from a SSLSocket.
And also, this deprecates a function ssl:connection_info/1, and
reimplements connection_info/1 with the new function.

Together with vertex and edge, label is a core type of digraph module
according to documentation and therefore should be exported as well.

filename:split("") returns [], while filename:split(<<"">>) returns
[<<"/">>].
Since the support in the filename module for binary arguments is
much more recent than support for strings, change
filename:split(<<"">>) so that it returns [].

It is needed in various tests. It uses the Ziggurat algorithm, which
is the fastest that I know.
|
|
As the erl_anno module is used by the compiler, it must be included
in the set of modules that are used when building the primary
bootstrap.
|
|
As long as the Erlang Compiler and qlc do not agree on the location of
LC warnings, qlc's own warnings about patterns and filters that always
fail have been silenced.
