-# Macros for reducing debug info size using dwz(1) utility.
-
-# The two default values below should result in dwz taking at most
-# 3GB of RAM or so on 64-bit hosts and 2.5GB on 32-bit hosts
-# on the largest *.debug files (in mid 2012 those are
-# libreoffice-debuginfo, debuginfos containing
-# libxul.so.debug and libwebkitgtk-*.so.*.debug).
-# This needs to be tuned based on the amount of available RAM
-# on build boxes for each architecture as well as virtual address
-# space limitations if dwz is 32-bit program. While it needs less
-# memory than 64-bit program because pointers are smaller, it can
-# never have more than 4GB-epsilon of RAM and on some architecture
-# even less than that (e.g. 2GB).
-
-# Number of debugging information entries (DIEs) above which
-# dwz will stop considering file for multifile optimizations
-# and enter a low memory mode, in which it will optimize
-# in about half the memory needed otherwise.
-%_dwz_low_mem_die_limit 10000000
-# Number of DIEs above which dwz will stop processing
-# a file altogether.
-%_dwz_max_die_limit 50000000
-
-# On x86_64 increase the higher limit to make libwebkit* optimizable.
-# libwebkit* in mid 2012 contains roughly 87mil DIEs, and 64-bit
-# dwz is able to optimize it from ~1.1GB to ~410MB using 5.2GB of RAM.

-# On ARM, build boxes often have only 512MB of RAM and are very slow.
-# Lower both the limits.
