bool boring_symbol	(	op_bfd_symbol const &	first,
		op_bfd_symbol const &	second
	)

return true if the first symbol is less interesting than the second symbol boring symbol are eliminated when multiple symbol exist at the same vma

linenr_info const find_nearest_line	(	bfd_info const &	ibfd,
		op_bfd_symbol const &	sym,
		bfd_vma	offset,
		bool	anon_obj
	)

Attempt to locate a filename + line number for the given symbol and offset.

The bfd object is either the object associated with the binary or the once associated with the separated debug info file so find_nearest_line() can't lookup the section contents of code section etc. The filepos of debuginfo symbols are different from the original file but we fixed symbol filepos earlier.
