See [Bug reports](https://github.com/erlang/otp/wiki/Bug-reports) +for more information. + +## Submitting Pull Requests + +You can contribute to Erlang/OTP by opening a Pull Request. + +## Fixing a bug + +* In most cases, pull requests for bug fixes should be based on the `maint` branch. +There are exceptions, for example corrections to bugs that have been introduced in the `master` branch. + +* Include a test case to ensure that the bug is fixed **and that it stays fixed**. + +* TIP: Write the test case **before** fixing the bug so that you can know that it catches the bug. + +* For applications without a test suite in the git repository, it would be appreciated if you provide a +small code sample in the commit message or email a module that will provoke the failure. + +## Adding a new feature + +* In most cases, pull requests for new features should be based on the `master` branch. + +* It is recommended to discuss new features on +[the erlang-questions mailing list](http://erlang.org/mailman/listinfo/erlang-questions), +especially for major new features or any new features in ERTS, Kernel, or STDLIB. + +* It is important to write a good commit message explaining **why** the feature is needed. +We prefer that the information is in the commit message, so that anyone that want to know +two years later why a particular feature can easily find out. It does no harm to provide +the same information in the pull request (if the pull request consists of a single commit, +the commit message will be added to the pull request automatically). + +* With few exceptions, it is mandatory to write a new test case that tests the feature. +The test case is needed to ensure that the features does not stop working in the future. + +* Update the [Documentation](https://github.com/erlang/otp/wiki/Documentation) to describe the feature. + +* Make sure that the new feature builds and works on all major platforms. Exceptions are features +that only makes sense one some platforms, for example the `win32reg` module for accessing the Windows registry. + +* Make sure that your feature does not break backward compatibility. In general, we only break backward +compatibility in major releases and only for a very good reason. Usually we first deprecate the +feature one or two releases beforehand. + +* In general, language changes/extensions require an +[EEP (Erlang Enhancement Proposal)](https://github.com/erlang/eep) to be written and approved before they +can be included in OTP. Major changes or new features in ERTS, Kernel, or STDLIB will need an EEP or at least +a discussion on the mailing list. + +## Before you submit your pull request + +* Make sure existing test cases don't fail. It is not necessary to run all tests (that would take many hours), +but you should at least run the tests for the application you have changed. +See [Running tests](https://github.com/erlang/otp/wiki/Running-tests). + +Make sure that your branch contains clean commits: + +* Don't make the first line in the commit message longer than 72 characters. +**Don't end the first line with a period.** + +* Follow the guidelines for [Writing good commit messages](https://github.com/erlang/otp/wiki/Writing-good-commit-messages). + +* Don't merge `maint` or `master` into your branch. Use `git rebase` if you need to resolve merge +conflicts or include the latest changes. + +* To make it possible to use the powerful `git bisect` command, make sure that each commit can be +compiled and that it works. + +* Check for unnecessary whitespace before committing with `git diff --check`. + +Check your coding style: + +* Make sure your changes follow the coding and indentation style of the code surrounding your changes. + +* Do not commit commented-out code or files that are no longer needed. Remove the code or the files. + +* In most code (Erlang and C), indentation is 4 steps. Indentation using only spaces is **strongly recommended**. + +### Configuring Emacs + +If you use Emacs, use the Erlang mode, and add the following lines to `.emacs`: + + (setq-default indent-tabs-mode nil) + (setq c-basic-offset 4) + +If you want to change the setting only for the Erlang mode, you can use a hook like this: + +``` +(add-hook 'erlang-mode-hook 'my-erlang-hook) + +(defun my-erlang-hook () + (setq indent-tabs-mode nil)) +``` diff --git a/bootstrap/lib/compiler/ebin/beam_asm.beam b/bootstrap/lib/compiler/ebin/beam_asm.beam Binary files differindex
