<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>
- <result> = malloc <type>[, i32 <NumElements>][, align <alignment>] <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(<type>)*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>

-<h5>Syntax:</h5>
-<pre>
- free <type> <value> <i>; yields {void}</i>
-</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>
