+\subsection{Split DWARF Objects}
+\label{datarep:splitdwarfobjects}
+A DWARF producer may partition the debugging
+information such that the majority of the debugging
+information can remain in individual object files without
+being processed by the linker. The first partition contains
+debugging information that must still be processed by the linker,
+and includes the following:
+\begin{itemize}
+\item
+The line number tables, range tables, frame tables, and
+accelerated access tables, in the usual sections:
+\dotdebugline, \dotdebugranges, \dotdebugframe,
+\dotdebugpubnames, \dotdebugpubtypes{} and \dotdebugaranges,
+respectively.
+\item
+An address table, in the \dotdebugaddr{} section. This table
+contains all addresses and constants that require
+link-time relocation, and items in the table can be
+referenced indirectly from the debugging information via
+the \DWFORMaddrx{} form, and by the \DWOPaddrx{} and
+\DWOPconstx{} operators.
+\item
+A skeleton compilation unit, as described in Section
+\refersec{chap:skeletoncompilationunitentries},
+in the \dotdebuginfo{} section.
+\item
+An abbreviations table for the skeleton compilation unit,
+in the \dotdebugabbrev{} section.
+\item
+A string table, in the \dotdebugstr{} section. The string
+table is necessary only if the skeleton compilation unit
+uses either indirect string form, \DWFORMstrp{} or
+\DWFORMstrx.
+\item
+A string offsets table, in the \dotdebugstroffsets{}
+section. The string offsets table is necessary only if
+the skeleton compilation unit uses the \DWFORMstrx{} form.
+\end{itemize}
+The attributes contained in the skeleton compilation
+unit can be used by a DWARF consumer to find the object file
+or DWARF object file that contains the second partition.
+
+The second partition contains the debugging information that
+does not need to be processed by the linker. These sections
+may be left in the object files and ignored by the linker
+(that is, not combined and copied to the executable object), or
+they may be placed by the producer in a separate DWARF object
+file. This partition includes the following:
+\begin{itemize}
+\item
+The full compilation unit, in the \dotdebuginfodwo{} section.
+Attributes in debugging information entries may refer to
+machine addresses indirectly using the \DWFORMaddrx{} form,
+and location expressions may do so using the \DWOPaddrx{} and
+\DWOPconstx{} forms. Attributes may refer to range table
+entries with an offset relative to a base offset in the
+range table for the compilation unit.
+
+\item Separate type units, in the \dotdebuginfodwo{} section.
+
+\item
+Abbreviations table(s) for the compilation unit and type
+units, in the \dotdebugabbrevdwo{} section.
+
+\item Location lists, in the \dotdebuglocdwo{} section.
+
+\item
+A skeleton line table (for the type units), in the
+\dotdebuglinedwo{} section (see
+Section \refersec{chap:skeletoncompilationunitentries}).
+
+\item Macro information, in the \dotdebugmacrodwo{} section.
+
+\item A string table, in the \dotdebugstrdwo{} section.

+\item A string offsets table, in the \dotdebugstroffsetsdwo{}
