# Note [The CI Story]
# ~~~~~~~~~~~~~~~~~~~
#
# There are two different types of pipelines:
#
#  - marge-bot merges to `master`. Here we perform an exhaustive validation
#    across all of the platforms which we support. In addition, we push
#    performance metric notes upstream, providing a persistent record of the
#    performance characteristics of the compiler.
#
#  - merge requests. Here we perform a slightly less exhaustive battery of
#    testing. Namely we omit some configurations (e.g. the unregisterised job).
#    These use the merge request's base commit for performance metric
#    comparisons.
#

workflow:
  # N.B. Don't run on wip/ branches, instead on run on merge requests.
