Make the Emacs Erlang mode TRAMP-aware when compiling. Thanks to Tomas Abrahamsson.
Own Id: OTP-11270
When cover:stop(Node) was called on a non-existing node, a process waiting for cover data from the node would hang forever. This has been corrected.
Own Id: OTP-10979
Make cover smarter about finding source from beam.
In particular, search using the source path in module_info if the current heuristic fails.
Own Id: OTP-10902

The BIF highlighting in the emacs mode has been updated to correspond with the correct BIFs.
Own Id: OTP-10774
Support for Unicode has been implemented.
Own Id: OTP-10302
A new function, cover:flush(Nodes), is added which will fetch data from remote nodes without stopping cover on those nodes. This is used by test_server and common_test when it is safe to assume that the node will be terminated after the test anyway. The purpose is to avoid processes crashing when re-loading the original beam if the processes is still running old code.
Remote nodes will now continue to count code coverage if the connection to the main node is broken. Earlier, a broken connection would cause the cover_server on the remote node to die and thus any still cover compiled modules would cause process crash when trying to insert cover data in ets tables that used to exist on the cover_server. The new functionality also involves synchronization with the main node if the nodes are reconnected.

Where necessary a comment stating encoding has been added to Erlang files. The comment is meant to be removed in Erlang/OTP R17B when UTF-8 becomes the default encoding.

Remove Erlang-specific compilation error regexp in erlang.el
Own Id: OTP-10168
Fix highlighting of atoms ending with a dollar sign
Like this: 'atom$'. In that example, the last single quote should be recognised as ending the atom. This needs a font-lock workaround similar to the one for strings. Thanks to Magnus Henoch
Own Id: OTP-10178
Xref now accepts filenames with character codes greater than 126. (Thanks to Emile Joubert for reporting the issue.)
Own Id: OTP-10192
Add test_indentation target to lib/tools/emacs/Makefile
Automatically indent test.erl.orig, save to test.erl, and compare to test.erl.intended. Thanks to Magnus Henoch.
Own Id: OTP-10226
Makefiles in erts, hipe and tools have been corrected to enable parallel make, i.e MAKEFLAGS=-jX where X is the parallelity number. As a result of this dependencies were corrected since that is what is needed for parallel make to work.

Update system profiling principles to reflect eprof performance improvements.
Own Id: OTP-9656
[cover] fix leftover {'DOWN', ..} msg in callers queue
After stopping cover with cover:stop() there could still be a {'DOWN',...} leftover message in the calling process's message queue. This unexpected leftover could be eliminated if erlang:demonitor/2 with option flush would be used in certain points
Own Id: OTP-9694
Add deps as erlang-flymake include directory.
Update erlang-flymake to recognize the "deps" folder as an include directory. This makes erlang-flymake compatible with the rebar dependency management tool's default folder structure, which puts included dependencies in "deps".(Thanks to Kevin Albrecht)

Teach the emacs mode to compile yecc and leex files
If visiting a .yrl or .xrl file in emacs with erlang-mode, then the `erlang-compile' function (normally bound to C-c C-k), now knows how to compile yecc and leex files, and then, if that compilation succeeds, also compiles the resulting .erl files.
Also introduce a `erlang-compile-command-function-alist' to make it possible to hook in other functions for computing compilation commands/expressions, depending on file name. (Thanks to Tomas Abrahamsson )
Own Id: OTP-9503
Bugs in xref(3) have been fixed. (Thanks to Matthias Lang.)
Own Id: OTP-9416
Change make:files to behave more like erlc
This change removes the unnecessary checks on the files when make:files is called and allows the error checking to be done in compile:file, where the error messages are produced. It does not affect the return value.
(Thanks to Sam bobroff)
Own Id: OTP-9179
add user specified compiler options on form reloading
In order to be able to test non-exported functions from another (test) module it is necessary to compile the specific module (at least during the test phase) with the export_all compiler option. This allows complete separation of testing and productive code. At the moment it is not possible to combine this with a test code coverage using the cover module. The problem is that when cover compiling a module using cover:compile_* the code is reloaded into the emulator omitting/filtering the passed user options. In my example above the export_all option would be removed and the non-exported functions cannot be called any more. (Thanks to Tobias Schlager)
Own Id: OTP-9204
Inhibit electric newline after "->" when inside a type spec
The Erlang mode for Emacs inserts a newline after every "->", which saves you one keystroke when writing a function, but that is inappropriate when writing a type spec, as you'd normally keep the spec on one line. This change inhibits the automatic insertion when the current line starts with "-spec" or "-type".(Thanks to Magnus Henoch)
Own Id: OTP-9255
Add a check logic to prevent file descriptor leak
cover module handle files as raw in export and import. Assert counts of ports are the same at the beginning and at the end of the test case.(Thanks to Shunichi Shinohara)
Own Id: OTP-9300
Declare indentation options as "safe" in erlang-mode for Emacs
Emacs has a facility for setting options on a per-file basis based on comments in the source file. By default, all options are considered "unsafe", and the user is queried before the variable is set. This patch declares the variables erlang-indent-level, erlang-indent-guard and erlang-argument-indent to be safe, if the value specified in the source file is valid.
Such declarations usually look like this:
%% -*- erlang-indent-level: 2 -*-
and appear on the first line of the file. (thanks to Magnus Henoch)
Own Id: OTP-9122
Cover has been improved to take less memory and allow parallel analysis of cover data. Data collection from nodes is now done in parallel and it is now possible to issue multiple analyse and analyse_to_file requests at the same time. A new function call async_analyse_to_file has also been introduced, see the documentation for more details.

Add lock profiling tool.
The Lock profiling tool, lcnt, can make use of the internal lock statistics when the runtime system is built with this feature enabled.
This provides a mechanism to examine potential lock bottlenecks within the runtime itself.
- Add erts_debug:lock_counters({copy_save, bool()}). This option enables or disables statistics saving for destroyed processes and ets-tables. Enabling this might consume a lot of memory.
- Add id-numbering for lock classes which is otherwise undefined.
