 |
|
Recently switched default linker to mold.
Having a whole set of /etc/portage/env files, it's quite easy to change per package build parameters.
I was wondering about lto/bfd & lto/mold binary size and experienced gui-apps/wlr-randr::guru which is just an example.
bfd got: | Code: | | image/usr/bin/wlr-randr lto-no: 31040 lto: 26944 diff: 4096 #bin |
mold got: | Code: | | image/usr/bin/wlr-randr lto-no: 26080 lto: 26944 diff: -864 #bigger-bin |
Both lto have same size. As expected...
Hey, wait!!! Plz check the non lto binary size 
Sorry I felt off my chair 
Every package installed here with lto size gain failure will be tested ld-bfd vs mold and reported here when mold does better.
Thks 4 ur attention, interest & support.

lto is no good for x11-wm/openbox.
mold lto-no binaries are much smaller though
