Add two further commits to ignored_commits, remove old ones
GCC's versioning script now ignores two new commit hashes and removes older, irrelevant ignored commits.
This update to GCC’s versioning script (git_update_version.py) adds two specific commit hashes to the ignored_commits list. These commits will now be excluded from the version string generation process, likely because they represent internal or cosmetic changes that shouldn’t affect the user-visible version number. Concurrently, older, no longer relevant commit hashes have been removed from the ignored list, streamlining the script’s maintenance.
In Details
The git_update_version.py script within GCC's gcc-changelog directory is responsible for generating the version string that identifies a specific GCC build. This script references a list of ignored_commits, which are commit hashes that should not influence the calculated version number. Typically, these are commits related to internal infrastructure, documentation, or trivial changes that don't warrant a version bump. This commit updates this list, adding two new hashes and pruning older ones, ensuring the versioning logic remains accurate and relevant to the project's development lifec…
For Context
Software projects, especially large ones like GCC, use version numbers (e.g., 11.2.0) to indicate specific releases and track changes. When you build GCC from its source code, a script automatically generates a detailed version string that often includes information about the exact changes incorporated. Sometimes, certain internal or minor changes to the compiler itself shouldn't affect this official version string, as they don't represent new features or bug fixes for end-users. The git_update_version.py script has a list of 'ignored commits' — specific internal changes that it should skip when calculating the version. This update simply adds two new such commits to that list and removes some old ones that are no longer relevant, ensuring that the automatically generated version numbers accurately reflect significant changes for users.
