++# 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.

++# 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.
