Hi, When pacman-6.0 is release, makepkg will provide the option to build packages using Link Time Optimisation (LTO) by default. This provides smaller, faster executables/DSOs, and improves GCC diagnostics. SUSE saw an average 5% decrease in binary size. In short, makepkg.conf will have: OPTIONS=(.... lto) When enabled, makepkg with add -flto to CFLAGS/CXXFLAGS The use of LTO can be disabled as needed in a PKGBUILD: options=('!lto') For full details and to comment, see: https://gitlab.archlinux.org/archlinux/rfcs/-/merge_requests/4 Allan
