<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>
