CreateReleases

The following part describes how the OpenRISC GCC maintainers create releases:

For plain gcc

• Fetch an upstream release from their repository (they have the form gcc-{version}-release.

• Merge this release into the OpenRISC branch (or a version branch)

• Create a branch or1k-{version}

• Create an annotated tag or1k-{version}-release

    git tag -a or1k-{version}-release -m "GCC {version} Release for OpenRISC"
  

• Push this tag: git push origin or1k-{version}-release

• Create the OpenRISC patch: git diff gcc-{version}-release > gcc-{version}-or1k.patch

• Visit the repository on GitHub and go to releases

  • Edit the new tag
  • Set release title: GCC {version} with OpenRISC patches
  • Upload the patch

For musl gcc patches

As musl is not part of GCC, we also patch GCC for musl:

• Branch or1k-{version} to musl-{version}
• Get the patches for the GCC version (branch per release)
• Apply the patches listed in series and commit similar to this commit
• Finally, apply the or1k-specific patch: git cherry-pick 3455e5a
• Push the branch

Where to go next

• Create a release of newlib, musl, etc.
• Update the RTEMS source builder
• Update openrisc.io with a post about your new release
• Send a mail to [email protected] with the details

Automation

Stafford has put together some scripts that help automate the build release parts above.

The or1k-toolchain-build project helps with:

• Build binaries for musl, newlib and nolib(no libc just binutils and gcc for linux builds)
• The binaries are built in a docker container for easy reproduction
• release.sh script to create the git tag, .patch files and github release draft
• upload.sh script to upload patches and binaries the the release
