Getting Started

• Locate and install the lab10 project into your eclipse workspace as directed by your instructor, following the usual instructions, including those for an ant build.
• Browse this lab document to get an idea of the work you will do for this assignment.

Procedure:

• Install the software as usual.
• Take a look at Contest.j, which is a jasmin program that, as provided, calls its static fibs method.
• Be certain only to modify the file Contest.j.
• Complete the Jasmin file Contest.j file as directed by the comments in that file.
• To assist you with the Jasmin part, there is on-line documentation here
• A more thorough guide to the Java VM instruction set can be found here
• Your solution must correctly pass the bytecode-verification stage of a JVM. That stage always runs by default, and the JVM will throw an exception or crash on bytecodes that do not verify.
• Submit your solution as usual.

Contest:

We will examine the size in bytecodes of each contest submission, and we will award a tasty prize for the smallest solution in each of the following categories:

• Verified: submissions to this category must bytecode-verify by a standard JVM.
• NonVerified: submissions to this category need not bytecode-verify. Solutions that need not verify can generally be shorter than those that do.

Submit your contest entry as directed by your instructor.

Your solution must clearly indicate via comments at the top if it is intended for the NonVerified category. We will otherwise assume that your solution should verify properly.
