91.305 Assignment 6:
The x86 Instruction Set and C-Language Compilation

 

Reading and Practice Problems

Read the following from Bryant and O’Hallaron, Chapter 3. Do the practice problems as indicated for each section.

  • Introduction (pp. 124–125)
  • 3.1, Historical Perspective (pp. 125–128).
  • 3.2, Program Encodings (pp. 128–134).
  • 3.3, Data Formats (pp. 135).
  • 3.4, Accessing Information (pp. 136–143); Practice Problems 3.1 and 3.2.
  • 3.5, Arithmetic and Logical Operations (pp. 143–148); Practice Problem 3.6.
  • 3.6, Control (pp. 148–170); Practice Problem 3.12.

Since answers are given in the book, the practice problems are done on the honor system. Basically, you should make an effort to solve them, and then use the solutions as necessary to confirm your understanding.

Some of the practice problems (e.g., 3.2) suggest that you actually sit down in front of a Linux machine, type in some C code, compile it (using the -S switch, which generates the assembly), and examine the result.

I highly recommend that you actually do this. It's a lot more interesting when you can see the gcc compiler at work. If you don't have an x86-based Linux machine of your own, log into one of the department’s machines (e.g., mercury) to do this.

To Turn In

Please turn in written solutions (prepared individually) for the following homework problems (starting on page 231 of the text).

It’s perfectly acceptable (or should I say, encouraged!) to type in C code and compile it (with -S) to help figure out the answers!
