+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:

+
+<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.
