I agree that ideally the linker would be able to do fine-grained GC of DWARF at 
the granularity of individual DIEs and other data items. However, implementing 
that would be a huge project. Currently AFAICT `lld` does very little DWARF 
processing. Wholesale DWARF rewriting would expand the scope of the linker and 
require lots of testing against various DWARF producers and consumers. I 
definitely wouldn't want to implement that.
