Final Project

Finish your compiler -- implement the register allocator, do final assembly of all the modules so that you can go all the way from Tiger source to assembler.

This will require you to define a few remaining machine-level bits and pieces of the modules. See chapter 12 of the course text for discussion. At the least, you should include:

• a main routine that reads in a file and saves assembly code to another file
• Frame.string properly implemented
• procEntryExit3 generating the proper cruft that SPIM expects
• procEntryExit2 updated to work with your particular code generator and register allocator

Reading sysspim.s and/or the output from "gcc -S" on an SGI may be helpful.

You should submit the following files:

• Any altered or new source code, including sources.cm
• A text file describing
  • The members of your team
  • A description of what new functionality you added to the final compiler for integration.
  • Anything you think is of interest about your code.
• An assembler listing for a program or procedure to compute factorial. If your compiler is missing critical phases and cannot compile a factorial program, then submit some compiled Tiger program. Insert stubs for pieces you are missing. (You may make this listing or listings part of your report.)
