LLD treats any symbol referenced from a linker script as a GC root, which makes sense. Unfortunately, it also processes --defsym as a linker script fragment internally, so all target symbols of a --defsym also get treated as GC roots (i.e., if you have something like --defsym SRC=TGT, TGT will become a GC root). I believe this to be unnecessary for defsym specifically, since you're just

...ange defsym targets specifically to not be considered as GC roots, so that they can be dead code eliminated.

I would like to make bar plots where the bars are composed of text like this: http://www.thomaslevine.com/lowres/text_bars.png Is there a package that will help me with this? Thanks Tom
