Our demonstration for Chapter 3 is elegant and easy to extend. Unfortunately,
it does not produce wonderful code. For example, when compiling simple code,
we don't get obvious optimizations:</p>

define double @test(double %x) {

%addtmp1 = add double %addtmp, %x
ret double %addtmp1
}
</pre>
</div>
<p>This code is a very, very literal transcription of the AST built by parsing
the input. As such, this transcription lacks optimizations like constant folding (we'd like to get "<tt>add x, 3.0</tt>" in the example above) as well as other more important
optimizations. Constant folding, in particular, is a very common and very
important optimization: so much so that many language implementors implement
constant folding support in their AST representation.</p>
<p>With LLVM, you don't need this support in the AST. Since all calls to build LLVM IR go through
the LLVM builder, it would be nice if the builder itself checked to see if there
was a constant folding opportunity when you call it. If so, it could just do
the constant fold and return the constant instead of creating an instruction.
