The GNU D Compiler (GDC) project was originally started by David Friedman +in 2004 until early 2007 when he disappeared from the D scene, and was no longer able to maintain GDC. +Following a revival attempt in 2008, GDC is now under the lead of Iain Buclaw who has been steering the +project since 2009 with the assistance of its contributors, without them the project would not have been +nearly as successful as it has been. + +Documentation on GDC is available from [the wiki][wiki]. Any bugs or issues found with using GDC should +be reported at [the GCC bugzilla site][bugs] with the bug component set to `d`. For help with GDC, the +[D.gnu][maillist] mailing list is the place to go with questions or problems. There's also a GDC IRC +channel at #d.gdc on FreeNode. Any questions which are related to the D language, but not directly to +the GDC compiler, can be asked in the [D forums][dforum]. You can find more information about D, including +example code, API documentation, tutorials and these forums at the [main D website][dlang]. + +### Building GDC + +Stable GDC releases for production usage should be obtained by downloading stable GCC sources +from the [GCC downloads][gcc-download] site. +For the latest experimental development version, simply download a [GCC snapshot][gcc-snapshot] or +checkout the GCC Git repository. Most GDC development directly targets the GCC Git repository, +so the latest GDC version is always available in the GCC Git. +Do not use the `ci/mainline` branch in this repository, as it is rebased regularly and contains exclusively +CI related changes. + +During certain development phases (e.g. when GCC is in a feature freeze) larger GDC changes may be staged +to the `devel/gdc` branch. This branch is rebased irregularly, do not rely on the commit ids to be +stable. + +If you need to clone this repo for some reason, you may want to do a shallow clone using the +`--depth 1 --no-single-branch` git options, as this repository is large. To compile GDC, add `--enable-languages=d` to the GCC configure flags and [start building][gdc-build]. + +### Using GDC + +Usage information can be found at ... + +### Contributing to GDC + +Starting with GCC 9.0.0, GDC has been merged into upstream GCC and all GDC development now follows the usual +GCC development process. Changes to GDC and related code can therefore be submitted +to the [gcc-patches mailing list][patches-ml] for review. + +It is possible to directly post patches to the [mailing list][patches-ml] and not to use this repository at all. +We however recommend using this repository to make use of the CI checks and the github review workflow. + +#### Submitting Changes + +To submit changes to GDC, simply fork this repository, create a new feature branch based on the `ci/mainline` branch, +then open a pull request against the **mainline** branch. We recommend using full clones for development, allthough +using shallow clones should also be possible. In code: + +```bash +# Initial one time setup: +# For repository on github, then clone your fork +git clone git@github.com:[you]/gcc.git +cd gcc +# Add the gdc repository as a remote +git remote add gdc git@github.com:D-Programming-GDC/gcc.git + +# Do this for every patch: +# Fetch latest upstream changes +git remote update +# Base a new branch on gdc/mainline +git checkout gdc/ci/mainline +git checkout -b pr12345 +# Make changes, commit +git commit [...] +git push origin pr12345:pr12345 +# Open a pull request on github, target branch: mainline +``` +Opening a pull request will automatically trigger our CI and test your changes on various machines. + +#### Changelogs +The GCC project requires keeping changes in the `Changelog` files. GCC ships a script which can generate +Changelog templates for us if we feed it a diff: +```bash +git diff gdc/ci/mainline | ./contrib/mklog +``` +*Note:* The above command generates the diff between `gdc/ci/mainline` and your local branch. If `gdc/ci/mainline` was +updated and you did a `git remote update`, `gdc/mainline` may have changes which are not yet in your branch. +In that case, rebase onto `gdc/mainline` first. + +The command outputs something like this: +``` +ChangeLog: + +2019-02-03 Johannes Pfau + + * test.d: New file. + +gcc/d/ChangeLog: + +2019-02-03 Johannes Pfau + + * dfile.txt: New file. + +libphobos/ChangeLog: + +2019-02-03 Johannes Pfau + + * phobosfile.txt: New file. + +``` + +The `ChangeLog:`, `libphobos/ChangeLog:` part gives the file into which the following changes need to be added. +Complete the changelog text and use the existing entries in the files for reference or see +the [GCC][changelog-doc] and [GNU][changelog-doc2] documentation. Also make sure to adhere to the line length limit of 80 characters. Then make the changelog somehow available for review: +Either commit the files, or preferable, just copy and paste the edited text output of `mklog` into your +pull request description. + + +### Getting Changes Into GCC Git + +After changes have been reviewed on github, they have to be pushed into the GCC Git. Pull requests will +not get merged into this repository. The following steps can be handled by GDC maintainers, although it is +possible to perform these by yourself as well. + +##### Sumbitting to the gcc-patches Mailing List + +Once the review and CI have passed on the github pull request page, the changes need to be submitted to the +`gcc-patches` mailing list. This can easily be done using [git send-email][git-send-email]: + +1. You might want to squash the commits. Each commit will become one email/patch so it might make sense + to combine commits here. +2. The changelog should preferrably be pasted into the email text, so do not include + commits modifying the changelog files. +3. If you had to regenerate any autogenerated files (e.g. configure from configure.ac) + you may keep these changes out of the patch for simplified review. The generated files + should still be present in the changelog. + +You'll have to configure `git send-email` once after you checked out the repository: +```bash +git config sendemail.to gcc-patches@gcc.gnu.org +``` +If you never used `git send-email` before, you'll also have to setup the SMTP settings once. +See [here][git-send-email] for details. + +Now to send the patches: +```bash +# Check which commits will be sent: +git log gdc/ci/mainline.. +# Check the complete diff which will be sent: +git diff gdc/ci/mainline.. +# Dry run to verify everything again +git send-email gdc/ci/mainline --annotate --dry-run +# Send the patches +git send-email gdc/ci/mainline --annotate +``` + +If you send multiple patches and want to write an introduction email, use the `--compose` argument for +`git send-email`. You can also generate patch files like this: +```bash +git format-patch gdc/ci/mainline.. +# Edit the *.patch files, add messages etc. +# Now send the patches +git send-email *.patch --dry-run +git send-email *.patch +``` + +##### Pushing Changes to Git + +This section is only relevant for GDC maintainers with GCC Git write access. There are certain rules when +pushing to Git, usually you're only allowed to push **after** the patches have been reviewed on the mailing list. +Refer to the [GCC documentation][gcc-git] for details. + +### Repository Information + +This repository is a fork of the [GCC git mirror][gcc-github]. + +#### Directory Structure + +All code branches contain the complete GCC tree. D sources are in `gcc/d` for the compiler +and in `libphobos` for the runtime library. Changes to files in `gcc/d/dmd` or `libphobos` +should be submitted to the [upstream dlang repositories][dlang-github] first if possible. +Refer to [gcc/d/README.gcc][gcc-d-readme] for more details. + +#### Branches + +Branches in this repository are organized in the following way: + +* CI branches: The `ci/mainline` branch and release branches `ci/gcc-*` are based on the same + branches in the upstream GCC git repository. The only changes compared to the upstream branches + are CI-related setup commits. CI branches are updated automatically to be kept in sync with + upstream and are rebased onto the upstream changes. These branches are effectively readonly: + We never merge into the branches in this repository. The CI related changes make it possible + to run CI based tests for any PR based on these branches, which is their sole purpose. +* The `devel/gdc` branch: If GCC is in a late [development stage][gcc-stage] this branch can accumulate + changes for the GCC release after the next one. It is essentially used to allow periodic merges from + [upstream DMD][dlang-github] when GCC development is frozen. Changes in the GCC `mainline` branch + are manually merged into this branch. When GCC enters stage 1 development again, this branch will be + rebased and pushed to upstream `mainline`. After that, the branch in this repository will be **rebased** + to mainline. +* Backport branches: The `gcc-*-bp` branches contain D frontend and library feature updates for released GCC versions. + Regression fixes should target the main `gcc-*-branch` branches instead, according to GCC rules. + + + +[home]: https://gdcproject.org +[dlang]: https://dlang.org +[gcc]: https://gcc.gnu.org +[dforum]: https://forum.dlang.org +[dmd]: https://github.com/dlang/dmd +[wiki]: https://wiki.dlang.org/GDC +[bugs]: https://gcc.gnu.org/bugzilla +[maillist]: https://forum.dlang.org/group/D.gnu +[email]: mailto:ibuclaw@gdcproject.org +[gcc-devel]: https://gcc.gnu.org/git/?p=gcc.git;a=shortlog +[patches-ml]: https://gcc.gnu.org/lists.html +[gcc-github]: https://github.com/gcc-mirror/gcc +[gcc-git]: https://gcc.gnu.org/gitwrite.html +[gcc-stage]: https://www.gnu.org/software/gcc/develop.html +[dlang-github]: https://github.com/dlang +[gdc-build]: https://wiki.dlang.org/GDC/Installation/Generic +[changelog-doc]: https://www.gnu.org/software/gcc/codingconventions.html#ChangeLogs +[changelog-doc2]: https://www.gnu.org/prep/standards/standards.html#Change-Logs +[git-send-email]: https://www.freedesktop.org/wiki/Software/PulseAudio/HowToUseGitSendEmail/ +[gcc-download]: https://www.gnu.org/software/gcc/releases.html +[gcc-d-readme]: https://github.com/D-Programming-GDC/gcc/blob/ci/mainline/gcc/d/README.gcc +[gcc-snapshot]: https://www.gnu.org/software/gcc/snapshots.html diff --git a/azure-pipelines.yml b/azure-pipelines.yml new file mode 100644 index 00000000000..8b9c1f5e72c --- /dev/null +++ b/azure-pipelines.yml @@ -0,0 +1,48 @@ +jobs: +- job: Windows + timeoutInMinutes: 120 + pool: + vmImage: 'vs2017-win2016' + strategy: + matrix: + x64: + OS: win64 + MODEL: 64 + ARCH: x64 + x86: + OS: win32 + MODEL: 32 + ARCH: x86 + steps: + - checkout: self + fetchDepth: 1 + - script: | + git clone https://github.com/lazka/msys2-ci-base.git %CD:~0,2%\msys64 + %CD:~0,2%\msys64\usr\bin\rm -rf %CD:~0,2%\msys64\.git + displayName: Install MSYS2 + - script: | + set PATH=%CD:~0,2%\msys64\usr\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem + %CD:~0,2%\msys64\usr\bin\pacman --noconfirm -Syyuu + displayName: Update MSYS2 + +- job: Linux_X86_ML + timeoutInMinutes: 120 + pool: + vmImage: 'ubuntu-16.04' + variables: + AZURE: 'true' + steps: + - checkout: self + fetchDepth: 1 + - script: | + ./buildci.sh setup + displayName: Install prerequisites + - script: | + ./buildci.sh build + displayName: Building GCC + - script: | + ./buildci.sh testsuite + displayName: Running testsuite + - script: | + ./buildci.sh unittests + displayName: Running unit tests diff --git a/buildci.sh b/buildci.sh new file mode 100755 index 00000000000..1a37d4956fc --- /dev/null +++ b/buildci.sh @@ -0,0 +1,542 @@ +#!/bin/bash +# This script is intended to be ran on platform on GitHub Action +# Other CI platforms in this script are legacy and only kept around to keep +# the configuration parts of it modularish. +# +# Following environmental variables are assume to be exported on GitHub Actions. +# +# - RUNNER_TOOL_CACHE +# - RUNNER_OS +# - GCC_CI_TARGET +# - GCC_CI_BOOTSTRAP +# +# See https://docs.github.com/en/actions/learn-github-actions/variables#default-environment-variables +# +## Top-level build system configration. +gcc_prereqs="gmp-6.1.0.tar.bz2 mpfr-3.1.6.tar.bz2 mpc-1.0.3.tar.gz isl-0.18.tar.bz2" +host_package="9" + +export CC="gcc-${host_package}" +export CXX="g++-${host_package}" +export GDC="gdc-${host_package}" +export MAKE="make" + +environment() { + ## Determine what flags to use for configure, build and testing the compiler. + ## Commonize CI environment variables. + # + # project_dir: directory of checked out sources. + # cache_dir: tarballs of downloaded dependencies cached + # between builds. + # log_dir: where to save testsuite logs to upload them + # build_host: host triplet that build is ran from. + # build_host_canonical: canonical version of host triplet. + # build_target: target triplet of the compiler to build. + # build_target_canonical: canonical version of target triplet. + # make_flags: flags to pass to make. + # build_bootstrap: whether to enable bootstrap build. + # + if [ "${SEMAPHORE}" = "true" ];
