+<h1>Status As Of August 1, 2006</h1>
+<p>HLVM is steadily progressing towards release 0.2. Here is the 
+status of HLVM as of between revisions #359 and #438.</p>
+<h2>General Update</h2>
+<ul>
+  <li>Work is steadily progressing towards the 0.2 release. Most of the
+  milestones have already been accomplished. What remains is to finish up the
+  real number arithmetic operators, finish the test case generator, and
+  implement JIT execution.
+  <li>We are now about three quarters through the 0.2 functionality set.</li>
+  <li>Lines Of Code in HLVM: 31044</li>
+  <li>Lines Of Doc  in HLVM: 3282</li>
+  <li>Code Productivity: 443 loc/day</li>
+  <li>Total Productivity: 490 lines/day</li>
+  <li>Progress slowed a bit in July as Reid had to attend to an out-of-town
+  consulting engagement for two weeks.</li>
+</ul>
+<h2>Functionality Changes</h2>
+<ul>
+  <li>There are now 127 node types in the AST. This is down a bit from the
+  previous status update since the intrinsics were removed as separate node
+  types. Instead, they are just named instances of other node types.
+  </li>
+  <li>There is now an intrinsic type name tokenizer. The RNG file is in the
+  <tt>hlvm/AST/Intrinsics.rng</tt> file.
+  <li>All ConstantValue classes except ConstantExpression are implemented. It 
+  is now possible to represent a constant of all the types HLVM currently 
+  supports.</li>
+  <li>Resolved confusion about Arguments, Parameters, NamedTypes, NamedValues,
+  etc.</li>
+  <li>Removed the Alias type, it wasn't useful. Each type definition is an
+  alias for a type.</li>
+  <li>Removed the "atom" element from the XML syntax. It was redundant as we
+  now just use "intrinsic" directly.</li>
+  <li>Octet types and literal constants are now implemented.</li>
+  <li>Bundles may no longer have empty content.</li>
+  <li>Significant improvements in validation of the AST tree.</li>
+  <li>Linkables are now Constants because the address of a linkable (variable
+  or function) is constant (after linking).</li>
+  <li>Type resolution was implemented properly. It now handles recursive 
+  types properly and somewhat transparently.</li>
+  <li>The node dumper was vastly improved. It now uses new interfaces in the
+  PassManager to dump individual types, variables, etc. You can access it from
+  the debugger via <tt>hlvm::dump(Node*)</tt> function.</li>
+  <li>The IndexOp operator was broken into a two operators: GetIndexOp and 
+  GetFieldOp. The former for UniformContainerTypes, the latter for 
+  DisparateContainerTypes. This simplifies the whole business of indexing the
+  container types.</li>
+  <li>Function argument handling is now implemented.</li>
+  <li>There is a new ConvertOp for type conversion of first-class values. It is
+  akin to the LLVM CastInst. Code generation for non-first-class values has not
+  yet been implemented.</li>
+  <li>The NInf, PInf, and NaN operators have been removed. There is no need to
+  provide operators for these values. Instead the IsPInf, IsNInf, and isNan
+  operators can be used to determine if a floating point value is one of the
+  special values.</li>
+</ul>
+<h2>Test Case Changes</h2>
+<ul>
+  <li>The main focus in the past month has been to get the automated test case
+  generator to generate better test cases. It now generates HLVM programs that
+  use most of the defined operators and types. Not all of them, however, result
+  in compilable tests. This will be remedied soon.</li>
+  <li>Numerous bugs have been found and fixed as a result of the test case
+  generator</li>
+</ul>
+<h2>Documentation Changes</h2>
+<ul>
+  <li>Not much progress here. Although it looks like I will be writing the
+  reference manual for the AST nodes soon.</li>
+  <li>One significant change: Chandler Carruth validated the "sanity" build
+  instructions in the Developer's Guide. He made several suggestions and
+  corrections to the documentation to ensure correct building of HLVM and all
+  its dependent software.</li>
+</ul>
+<h2>Other Changes and News</h2>
+<ul>
+  <li>None.</li>
+</ul>
