OS Exercise 10 graded

Exercise 10 submissions have been graded and posted at the Exercise Grade page (internal access only). If you have any question about your exercise grades, please contact the instructor.

Amendments to rules and policies possible

From this year, (for the section I teach), the Operating Systems course has been downgraded from a 3rd-year course to a 2nd-year course (personally, this decision does not make sense and is inappropriate). As a result, we plan to make changes to the rules and policies for the course. When the changes are made, they will be announced on this board.

LP Exercise 10 (additional info)

The assumptions for Problems 2 were not sufficient. Please use the following code for the first few lines:

case CHAR-STRING: /* handles a[i] */
  t1 <- expr(i);
        /* t1 is assigned the register name having 
        the value of i */
  t2 <- base(a);
        /* t2 is assigned the register name having 
        the address of a[0]* /

LP Exercise 6

Today's problems are posted on the Execise Page.

Please, always think:

• you have to submit the exercise by 1440
• it takes some time to print and staple your exercise
• there's almost always a long queue for printer jobs, especially after 1430
• then when should you stop working ????

The length of the time to work for exercise is equal for everyone, it's up to you how to use it.

You don't have to use _subscript in the SSA form, just write a number next to the variable. That is, x₀ is good but not needed, x0 is enough.
