-<p>The <a href="/testresults/">Nightly Tester</a> is a simple perl script
-(located in <tt>utils/NightlyTest.pl</tt>) which runs every night to generate a
-daily report. It could use the following improvements:</p>

-<li>Regression tests - We should run the regression tests in addition to the

+<p>Sometimes creating new things is more fun than improving existing things.
These projects tend to be more involved and perhaps require more work, but can
also be very rewarding.</p>
<li>Implement a flow-sensitive context-insensitive alias analysis algorithm<br>

<li>Implement a strength reduction pass</li>
<li>Value range propagation pass</li>

<ol>
-<li>Write a new frontend for some language (Java? OCaml? Forth?)</li>
+<li>Port the <A HREF="http://www-sop.inria.fr/mimosa/fp/Bigloo/">Bigloo</A>
+Scheme compiler, from Manuel Serrano at INRIA Sophia-Antipolis, to
+output LLVM bytecode. It seems that it can already output .NET
+bytecode, JVM bytecode, and C, so LLVM would ostensibly be another good
+candidate.</li>
+<li>Write a new frontend for some other language (Java? OCaml? Forth?)</li>
<li>Write a new backend for a target (IA64? MIPS? MMIX?)</li>
+<li>Write a disassembler for machine code that would use TableGen to output
+<tt>MachineInstr</tt>s for transformations, optimizations, etc.</li>
<li>Random test vector generator: Use a C grammar to generate random C code;
run it through llvm-gcc, then run a random set of passes on it using opt.
Try to crash opt. When opt crashes, use bugpoint to reduce the test case and
mail the result to yourself. Repeat ad infinitum.</li>
+<li>Design a simple, recognizable logo.</li>
