Assignment 4, due June 21

Do problems 7, 9 and 11 at the end of Chapter 3 of the notes.
What features of the EAL assembler would prevent your converting EAL from a 2-pass assembler to a 1-pass assembler with chaining used to resolve forward references?
The fictional Ultimate RISC computer has one machine instruction, move, which moves an operand from the source address to the destination address. From the assembler's point of view, this is defined as follows:
```
	MOVE src,dst
```
Assembles identically to these two lines of EAL code
```
	W    src
	W    dst
```
If you are curious about the machine itself, see http://homepage.cs.uiowa.edu/~dwjones/arch/risc/, but nothing about the details of the actual machine matters to this problem.
Look in the code for EAL, in file parser.c and find the code for processing the B and W pseudo-ops (right before the else clause that generates the error message illegal opcode or pseudo-op). Write the code you would add here (starting with } else if ...) to handle the MOVE opcode. Assume that move_handle is defined for you.
