Then you just add a line to every git commit message:
Signed-off-by: Joe Smith <joe.smith@email.com>
Use your real name (sorry, no pseudonyms or anonymous contributions.)
If you set your user.name and user.email git configs, you can sign your commit automatically with git commit -s.
- Create a personal fork of the project on GitHub.
- Use sycl branch as baseline for your changes.
- Prepare your patch (follow LLVM coding standards).
- Build the project and run all tests (see GetStartedWithSYCLCompiler.md)
- Create a pull request for your changes following Creating a pull request instructions.
- When the pull request is created signed-off check is done.
- check_pr - verifies that the signed-off mark is added to each commit message.
- Once the pull request is approved by an Intel representative, build and functional testing are started.
- sycl-ubu-x64-pr - runs all LIT tests on machine with OpenCL runtimes for CPU and GPU.
- Approval is lost once the PR branch is updated. New approval and checks rerun are required.
- Once approval is received and all checks pass, the pull request is ready to be merged.
Merge of pull request is done only by project maintainers. There are three options:
- [Rebase and merge] The preferable choice for PRs containing a single commit.
- [Squash and merge] Used when there are multiple commits in the PR. Squashing is done to shorten history and make sure that the project is buildable on any commit.
- [Create a merge commit] Used for pull down PRs to avoid duplication of LLVM commits.
