+<p>Then, each non-native object file is added to the code generator with:</p>
+
+<pre class="doc_code">
+lto_codegen_add_module(lto_code_gen_t, lto_module_t)
+</pre>
+
+<p>The linker then has the option of setting some codegen options. Whether or
+not to generate DWARF debug info is set with:</p>
+
+<pre class="doc_code">lto_codegen_set_debug_model(lto_code_gen_t)</pre>
+
+<p>Which kind of position independence is set with:</p>
+
+<pre class="doc_code">lto_codegen_set_pic_model(lto_code_gen_t) </pre>
+
+<p>And each symbol that is referenced by a native object file or otherwise must
+not be optimized away is set with:</p>
+
+<pre class="doc_code">
+lto_codegen_add_must_preserve_symbol(lto_code_gen_t, const char*)
+</pre>
+
+<p>After all these settings are done, the linker requests that a native object
+file be created from the modules with the settings using:</p>
+
+<pre class="doc_code">lto_codegen_compile(lto_code_gen_t, size*)</pre>
+
+<p>which returns a pointer to a buffer containing the generated native
+object file. The linker then parses that and links it with the rest
+of the native object files.</p>
