  Project 5a, bug fixes
  This update is applied to Thursday's update. If you're unsure of which files to get at this point, just go to the project 5 source directory listing (from Tuesday Mar 27), and get all the files. They are the most recent updates.

  This update fixes problems with comparison and branching instructions. Each comparison was setting one or more flags in the CPSR, but the old flags were not getting cleared first.

  New project deadline: Tuesday Apr 3, midnight
  ExecutionUnit.hs

  Additional update 3:15PM. These updates fix a potential problem with displaying values in the data area when you are using the debugger.
  Decoder.hs
  Encoder.hs
  Instruction.hs

• Tuesday Apr 3
  Project 5a, bug fix
  This update is applied to Monday's update, and replaces Monday's ExecutionUnit.hs file. The add instruction now correctly allows you to add an 8-bit constant to a register, like this: ``Add (Reg R0) (Reg R0) (Con 4)''.
  ExecutionUnit.hs

  Project 6 update
  You can either get just these update files, or get all the files in the project 6 source directory if you have not yet done so. That directory contains the updated files.
  Assembler.hs (fixes branch ``decode'' problem) Get the Apr 11 update instead
  p1.arm (places ``#'' before all constant numbers)

  6:00 PM
  This fixes a bug which caused strings to be loaded incorrectly into a buffer when entered using swi #4.
  Loader.hs
  Swi.hs

• Wednesday Apr 11
  Project 6 update
  Some of you had the problem where labels were not being recognized. In fact the problem lay elsewhere, but these updates now provide you with meaningful (if not very descriptive) error messages, including the line number of the offending instruction. You should get these updates even if you have not experienced any problems.
  Arm.hs
  Assembler.hs
  Parser.hs

  Project 8 update
  A bug in this file accidentally re-enabled interrupts if you used the cmp instruction inside your interrupt handler.
  ExecutionUnit.hs

• Thursday May 3
  Project 8 update
  I have added some new commands to the debugger to allow you to set up and dump separate ranges of memory. This is useful for watching the values in separate stacks. The command ``e'' lets you set up a dump range (any number of them can be set up), and ``u'' lets you select a range to dump.
  Debugger.hs
