<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>
<li>Make the compiler driver use the LLVM linking facilities (with IPO)
before depending on GCC to do the final link.</li>
<li>Clean up parsing. It doesn't handle errors very well.</li>
