-<p>
- This intrinsic is used when stack protectors are required. LLVM generates a
- call to load the randomized stack protector guard's value. The intrinsic is
- used so that LLVM can ensure that the stack guard is placed onto the stack in
- the appropriate place—before local variables are allocated on the stack.

-<h5>Syntax:</h5>
-<pre>
-declare void @llvm.stackprotector( i8* <guard>, i8** <slot> )
-
-</pre>
-<h5>Overview:</h5>
-<p>
- The <tt>llvm.stackprotector</tt> intrinsic takes the <tt>guard</tt> and stores
- it onto the stack at <tt>slot</tt>. The stack slot is adjusted to ensure that
- it's before local variables are allocated on the stack.
-</p>
-<h5>Arguments:</h5>
-<p>
- The <tt>llvm.stackprotector</tt> intrinsic requires two pointer arguments. The
- first argument is the value loaded from the stack guard
- <tt>@__stack_chk_guard</tt>. The second variable is an <tt>alloca</tt> that
- has enough space to hold the value of the guard.
-</p>
-<h5>Semantics:</h5>
-<p>
- This intrinsic causes the prologue/epilogue inserter to force the position of
- the <tt>AllocaInst</tt> stack slot to be before local variables on the
- stack. This is to ensure that if a local variable on the stack is overwritten,
- it will destroy the value of the guard. When the function exits, the guard on
- the stack is checked against the original guard. If they're different, then
- the program aborts by calling the <tt>__stack_chk_fail()</tt> function.
