Hello, in my development I learned the hard way that the only linker which works with gnustep/libobjc2 seems to be the gold linker. standard ld as well as lvm's lld had issues with libobjc2 either by not doing stuff as it should or by optimizing things away it shouldnt. At least on Debian9 where I failed miserably when I tested (things might have changed since).
I'm happy in terms of functionality with gold linker but linking my projects is quite slow. My projects has around five thousands source files. All very small but still lots of them. So linking is taking most of the time when I modify and run something. Today I learned about the mold linker which is heavily paralelized speeding up linking in some tests by a factor of 20x. That's quite an achievement. This is wonderful for turnaround times while developing. Now as libobjc2 has a few specialities I wonder if anyone has ever tested mold with it and what the findings where. Mold's Project page is https://github.com/rui314/mold Andreas
