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

ad2206d5766 Revert "Delete MALLOC_ABI_ALIGNMENT define from pa32-linux.h"

Notes

Failed to apply to the post-commit baseline. This can happen if your commit requires a recently-commited patch in order to apply. The pre-commit CI will only perform a build since it doesn't know what dejagnu testsuite failures are expected on the tip-of-tree.

If you would like us to re-run this patch once the baseline reaches a different hash, please email us at patchworks-ci@rivosinc.com with a link to your patch.
