| # This file defines pre-commit CI for libc++, libc++abi, and libunwind (on Github). | ||
| # | ||
| # We split the configurations in multiple stages with the intent of saving compute time | ||
| # when a job fails early in the pipeline. This is why the jobs are marked as `continue-on-error: false`. | ||
| # We try to run the CI configurations with the most signal in the first stage. | ||
| # | ||
| # Stages 1 & 2 are meant to be "smoke tests", and are meant to catch most build/test failures quickly and without using | ||
| # too many resources. | ||
| # Stage 3 is "everything else", and is meant to catch breakages on more niche or unique configurations. | ||
| # | ||
| # Therefore, we "fail-fast" for any failures during stages 1 & 2, meaning any job failing cancels all other running jobs, | ||
| # under the assumption that if the "smoke tests" fail, then the other configurations will likely fail in the same way. | ||
| # However, stage 3 does not fail fast, as it's more likely that any one job failing is a flake or a configuration-specific | ||
