-heap profile policy: POLICY_DEEP_2
-#
-# This file contains a classification policy for dmprof.py.
-#
-# Each line indicates a group to be classified and conditions for classifying
-# in the following format.
-#   Format: <group-name> <region-type> <pattern>
-#
-# <group-name> is a name for the group to be classified.  Same names can appear
-# in the same policy file multiple times.  <region-type> represents a type of
-# the memory region.  It's one of {malloc, mmap, default, optional}.  <pattern>
-# is a Python-style regular expression to match with calling stack frames.
-#
-# For each memory chunks allocated by malloc, its calling stack frame of malloc
-# is compared with these classification policies whose <region-type> is 'malloc'
-# from the top.  If <pattern> of the policy matches the frame, the memory chunk
-# is classified into <group-name>.  The same way for 'mmap'.
-#
-# Policy lines whose <region-type>s are 'optional' and 'default' are used by
-# dmprof.py internally.  'optional' policies can be disabled by removing or
-# commenting-out.
