 <p>A key design point of an SSA-based representation is how it represents
    memory.  In LLVM, no memory locations are in SSA form, which makes things
-   very simple.  This section describes how to read, write, allocate, and free

-<h5>Syntax:</h5>
-<pre>
-  &lt;result&gt; = malloc &lt;type&gt;[, i32 &lt;NumElements&gt;][, align &lt;alignment&gt;]     <i>; yields {type*}:result</i>
-</pre>
-
-<h5>Overview:</h5>
-<p>The '<tt>malloc</tt>' instruction allocates memory from the system heap and
-   returns a pointer to it. The object is always allocated in the generic
-   address space (address space zero).</p>
-
-<h5>Arguments:</h5>
-<p>The '<tt>malloc</tt>' instruction allocates
-   <tt>sizeof(&lt;type&gt;)*NumElements</tt> bytes of memory from the operating
-   system and returns a pointer of the appropriate type to the program.  If
-   "NumElements" is specified, it is the number of elements allocated, otherwise
-   "NumElements" is defaulted to be one.  If a constant alignment is specified,
-   the value result of the allocation is guaranteed to be aligned to at least
-   that boundary.  If not specified, or if zero, the target can choose to align
-   the allocation on any convenient boundary compatible with the type.</p>
-
-<p>'<tt>type</tt>' must be a sized type.</p>
-
-<h5>Semantics:</h5>
-<p>Memory is allocated using the system "<tt>malloc</tt>" function, and a
-   pointer is returned.  The result of a zero byte allocation is undefined.  The
-   result is null if there is insufficient memory available.</p>
-
-<h5>Example:</h5>
-<pre>
-  %array  = malloc [4 x i8]                     <i>; yields {[%4 x i8]*}:array</i>
-
-  %size   = <a href="#i_add">add</a> i32 2, 2                        <i>; yields {i32}:size = i32 4</i>
-  %array1 = malloc i8, i32 4                    <i>; yields {i8*}:array1</i>
-  %array2 = malloc [12 x i8], i32 %size         <i>; yields {[12 x i8]*}:array2</i>
-  %array3 = malloc i32, i32 4, align 1024       <i>; yields {i32*}:array3</i>
-  %array4 = malloc i32, align 1024              <i>; yields {i32*}:array4</i>
-</pre>
-
-<p>Note that the code generator does not yet respect the alignment value.</p>

-</pre>
-
-<h5>Overview:</h5>
-<p>The '<tt>free</tt>' instruction returns memory back to the unused memory heap
-   to be reallocated in the future.</p>
-
-<h5>Arguments:</h5>
-<p>'<tt>value</tt>' shall be a pointer value that points to a value that was
-   allocated with the '<tt><a href="#i_malloc">malloc</a></tt>' instruction.</p>
-
-<h5>Semantics:</h5>
-<p>Access to the memory pointed to by the pointer is no longer defined after
-   this instruction executes.  If the pointer is null, the operation is a
-   noop.</p>
-
-<h5>Example:</h5>
-<pre>
-  %array  = <a href="#i_malloc">malloc</a> [4 x i8]                     <i>; yields {[4 x i8]*}:array</i>
