Just some info regarding code sizes and GCC options I used some specific gcc and ld options on my gentoo server installation (I use it cause it's a lot easier in terms of developer usage)
Additional CFLAGS: -fivopts -fomit-frame-pointer -ftree-loop-im -ffunction-sections -fdata-sections -fwhole-program -flto Additional LDFLAGS: -Wl,--as-needed -Wl,--hash-style=gnu -Wl,--gc-sections -flto" Some size reduction numbers: htop from 140Kb to 102Kb 7z from 436Kb to 286Kb 7za from 1178Kb to 960Kb git from 1300Kb to 1038Kb transmission (O_o) : from -rwxr-xr-x 1 root root 385596 Apr 26 12:00 transmission-cli -rwxr-xr-x 1 root root 388172 Apr 26 12:00 transmission-create -rwxr-xr-x 1 root root 391008 Apr 26 12:00 transmission-daemon -rwxr-xr-x 1 root root 383696 Apr 26 12:00 transmission-edit -rwxr-xr-x 1 root root 419784 Apr 26 12:00 transmission-remote -rwxr-xr-x 1 root root 384084 Apr 26 12:00 transmission-show to -rwxr-xr-x 1 root root 330640 Apr 28 12:44 /usr/bin/transmission-cli -rwxr-xr-x 1 root root 30940 Apr 28 12:44 /usr/bin/transmission-create -rwxr-xr-x 1 root root 334772 Apr 28 12:44 /usr/bin/transmission-daemon -rwxr-xr-x 1 root root 26992 Apr 28 12:44 /usr/bin/transmission-edit -rwxr-xr-x 1 root root 73844 Apr 28 12:44 /usr/bin/transmission-remote -rwxr-xr-x 1 root root 36244 Apr 28 12:44 /usr/bin/transmission-show Actually, I dont think about using it in a system-scale (due to some regressions mainly in LTO), but we can test and use this flags with some packages. With best regards, Alexander.
