title: SHLD+BSR decoder?
body: <p>Reading the following <a href="http://www.virtualdub.org/blog/pivot/entry.php?id=205" rel="nofollow">blog post</a>. A so called "SHLD+BSR" huffman decoder is mentioned, which is then further expanded to <code>MOV, MOV, SHLD, OR, BSR, MOV, SHR, MOV, OR, ADD, ADC</code>, however I have not found any reference or source code that describes such decoding. Does anyone know what decoding method is referred?</p>
