hi Reid,

thanks for the documentation for this. Me too struggled at first with
this concept.

Regarding the page fragment references:

<a href="firstptr">What is the first index of the GEP instruction?</a>
    </li>
    <li><a href="extra_index">Why is the extra 0 index required?</a></li>

    <li><a href="deref">What is dereferenced by GEP?</a></li>
    <li><a href="lead0">Why don't GEP x,0,0,1 and GEP x,1 alias? </a></li>
    <li><a href="trail0">Why do GEP x,1,0,0 and GEP x,1 alias? </a></li>

I think you should put a # in fron of the href values, otherwise my
preferred browser (firefox) thinks it is a website and not a document
fragment.
