+<p>
+Modules may contain "module-level inline asm" blocks, which corresponds to the
+GCC "file scope inline asm" blocks.  These blocks are internally concatenated by
+LLVM and treated as a single unit, but may be separated in the .ll file if
+desired.  The syntax is very simple:
+</p>
+
+<div class="doc_code"><pre>
+  asm "inline asm code goes here"
+  asm "more can go here"
+</pre></div>
+
+<p>The strings can contain any character by escaping non-printable characters.
+   The escape sequence used is simply "\xx" where "xx" is the two digit hex code
+   for the number.
+</p>
+
+<p>
+  The inline asm code is simply printed to the machine code .s file when
+  assembly code is generated.
+</p>
