# 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.
%_dwz_max_die_limit_x86_64 110000000
# On ARM, build boxes often have only 512MB of RAM and are very slow.
# Lower both the limits.
