# This CI is used to test Arm cases. We can set the maximum 16 tasks.
# The entire testing design is inspired from .github/workflows/compilers.yml.

# By default, Cirrus mounts an empty volume to `/tmp`
# which triggers all sorts of warnings like "system temporary path is world-writable: /tmp".
# Lets workaround it by specifying a custom volume mount point.
