CS 2734 Computer Organization II

This is the final part of the MAC-1 assembler. Do the following prior to the laboratory.

• Create a separate directory and copy your programs from Laboratory 8 into it.

• The assembler should use Pass 1 as specified in laboratory 8.

• The assembler takes the following command-line options:

          -o filename1
          -s filename2
  

  If -o is given, the assembler writes the assembled code to filename1, otherwise the assembler writes the assembled code to a.out. If -s is given, the assembler writes the symbol table in ASCII to filename2 at the end of Pass 1. The assembled code should be written out in ASCII hex.

• You should reuse as much code as possible from Pass 1 in implementing Pass 2.

• You should correctly handle errors in the assembly language source.

• Your program should be well-structured and well-documented. Each function should have a header describing the function and specifying the meaning of each parameter.

• You should test your program on the following files prior to being checked off:
  • Test Program 1
  • Test Program 2
  • Test Program 3
  • Test Program 4
  • Test Program 5
  • Test Program 6
  • Test Program 7

• Test File 1:
  • 1.in: Input file containing MAC-1 source code.
  • 1.out: Output file containing MAC-1 executable.
  • 1.err: List of assembly errors.
  • 1.symTable: Symbol table.
  • 1.trace: Trace of pass 1 (for debugging purposes).
  • 1_tmp: Temporary file written in pass 1, read in pass 2

• Test File 7:
  • 7.in: Input file containing MAC-1 source code.
  • 7.out: Output file containing MAC-1 executable.
  • 7.err: List of assembly errors.
  • 7.symTable: Symbol table.
  • 7.trace: Trace of pass 1 (for debugging purposes).
  • 7_tmp: Temporary file written in pass 1, read in pass 2
