# Note [Cross-compiler stripping]
# gcc requires delicate stripping as it installs ELF files for both
# HOST and TARGET platforms. It requires according strip tool otherwise
# strip could remove sections it's not aware of.
# Example ARM breakage by x86_64 strip: https://bugs.gentoo.org/697428
#
# Let's recap the file layout for directories with object files for a
# cross-compiler:
#
# $out (host != target)
# `- bin: HOST
# lib/*.{a,o}: HOST
# `- gcc/<TARGET>/<VERSION>/*.{a,o}: TARGET
# `- plugin/: HOST
# `- lib{,32,64,x32}: symlink to lib or identical layout
# `- libexec/: HOST
# `- <TARGET>/: TARGET
#
# $out (host == target) has identical directory layout.
#
# $lib (host != target):
# `- <TARGET>/lib/*.{la,so}: TARGET
#
# $lib (host == target):
# `- lib/*.{la,so}: HOST
# The rest of stripDebugList{Host,Target} will be populated in
# postInstall to disambiguate lib/ object files.
stripDebugList = [ "bin" "libexec" ];
