# Ada warning options:
#
# a Activate most optional warnings.
# .e Activate every optional warnings.
# e Treat warnings and style checks as errors.
#
# D Suppress warnings on implicit dereferences:
# As SPARK does not accept access types we have to map the
# dynamically chosen register locations to a static SPARK
# variable.
#
# .H Suppress warnings on holes/gaps in records:
# We are modelling hardware here!
#
# H Suppress warnings on hiding:
# It's too annoying, you run out of ideas for identifiers fast.
#
# T Suppress warnings for tracking of deleted conditional code:
# We use static options to select code paths at compile time.
#
# U Suppress warnings on unused entities:
# Would have lots of warnings for unused register definitions,
# `withs` for debugging etc.
#
# .U Deactivate warnings on unordered enumeration types:
# As SPARK doesn't support `pragma Ordered` by now, we don't
# use that, yet.
#
# .W Suppress warnings on unnecessary Warnings Off pragmas:
# Things get really messy when you use different compiler
# versions, otherwise.
# .Y Disable information messages for why package spec needs body:
# Those messages are annoying. But don't forget to enable those,
# if you need the information.
