Notes

Testsuite results use a more lenient allowlist to reduce error reporting with flakey tests. Please take a look at the current allowlist. Results come from a sum file comparator. Each patch is applied to a well known, non-broken baseline taken from our gcc postcommit framework (here) which runs the full gcc testsuite every 6 hours. If you have any questions or encounter any issues which may seem like false-positives, please contact us at patchworks-ci@rivosinc.com
