by the compiler. That means you don't have to futz around with figuring out how
to get the keyword recognized. It already is. The part of the compiler that
you need to implement is the <code>ROLL</code> case in the
<code>StackerCompiler::handle_word(int)</code> method.</p> See the implementations
of PICk and SELECT in the same method to get some hints about how to complete
this exercise.<p>

<li>Enhance to run on 64-bit platforms like SPARC. Right now the size of a
pointer on 64-bit machines will cause incorrect results because of the 32-bit
size of a stack element currently supported. This feature was not implemented
because LLVM needs a union type to be able to support the different sizes
correctly (portably and efficiently).</li>

<li>Write an LLVM pass to optimize the use of the global stack. The code
emitted currently is somewhat wasteful. It gets cleaned up a lot by existing
passes but more could be done.</li>
<li>Add -O -O1 -O2 and -O3 optimization switches to the compiler driver to
allow LLVM optimization without using "opt."</li>

depending on GCC to do the final link.</li>

<li>Rearrange the StackerCompiler.cpp code to make better use of inserting
instructions before a block's terminating instruction. I didn't figure this
technique out until I was nearly done with LLVM. As it is, its a bad example
