+Native Object File Wrapper Format
+=================================
+
+Bitcode files for LLVM IR may also be wrapped in a native object file
+(i.e. ELF, COFF, Mach-O). The bitcode must be stored in a section of the
+object file named ``.llvmbc``. This wrapper format is useful for accommodating
+LTO in compilation pipelines where intermediate objects must be native object
+files which contain metadata in other sections.
+
+Not all tools support this format.
