<li><p>The most visible end-user change in LLVM 2.4 is that it includes many
optimizations and changes to make -O0 compile times much faster. You should see
improvements on the order of 30% or more faster than LLVM 2.3. There are many
improvements on the order of 30% (or more) faster than LLVM 2.3. There are many
pieces to this change, described in more detail below. The speedups and new
components can also be used for JIT compilers that want fast compilation as
well.</p></li>
