I've switched back and forth between gold and lld a couple times. Eventually I always get frustrated by lld causing slowdowns and other issues for gdb.

Yea. gold also isn't really maintained anymore, so it'd be nice to move on... > There is another linker called mold [2].

Yea, didn't yet quite seem there yet last time I looked, and lld seems plenty fast for our purposes. Greetings, Andres Freund
