Squash. +# +# When applied, this patch makes some minor adjustments to some assembly +# language routines in UXP for the x86 architecture. Once these adjustments +# are made, UXP can be compiled with LTO (link-time optimization), given a +# proper 'mozconfig' file. +# +# The author discovered that you need to use the following extra lines in your +# mozconfig file in order for LTO to work on the x86 architecture (replace all +# instances of `[n]` with the number of parallel LTO jobs you want -- it's +# generally safe to use the same number here that you use in +# `MAKEOPTS="-j[n]"`): +# +# ``` +# export CFLAGS="${CFLAGS} -flto=[n]" +# export CXXFLAGS="${CXXFLAGS} -flto=[n]" +# export LDFLAGS="${LDFLAGS} -Wl,-z,norelro" +# ac_add_options --disable-elf-hack +# ac_add_options --disable-gold +# ``` +# You may also want to add "${CFLAGS}" to the `--enable-optimize` option, if +# you want to ensure everything gets LTO-optimized. +# +#=============================================================================== +# +# This patch *appears to be* stable. It does not seem to adversely affect +# UXP, though the author stresses that this patch needs to be tested more widely +# before any conclusions can be drawn about its stability. +# +# WARNING! This is not an official patch in any way, shape or form!
