> FWIW in one of comments (it was edited later) of this patch I saw error message like "error: failed to compute relocation..." that comes from DWARFContextInMemory which LLD uses for error reporting. I suppose LLD currently unable to report correct line numbers for AVR because of that. Looks just AVR target should be implemented in RelocVisitor.
Where is RelocVisitor? could you give me a hint? thanks!
