36 # To define a new flag, simply add it to this list.
176 # "Compound" flags correspond to a set of base flags. These exist
177 # solely for convenience in setting them via the command line: if a
178 # compound flag is specified, all of the corresponding base flags are
179 # set. Compound flags cannot be used directly in DPRINTFs etc.
180 # To define a new compound flag, add a new entry to this hash
181 # following the existing examples.
