Quiz submission record for quiz2-2-2 at Wed Jun 30 23:30:12 2004: Your Answer for Question 1: The convention is to use two classes of registers to avoid saving and restoring a register whose value is never used: the 10 temporary registers $t0-$t9 and 8 saved registers $s0-$s7. Your Answer for Question 2: I'm not sure if I understand what this questions is asking, but I'm going to go with the base case. In scheme, I got lots of errors that had something to do with the base case, like "invalid argument to first" Your Answer for Question 3: I'm finding it harder to understand the reading everyday because I am behind with MIPS. It was hard for me to understand MIPS code. MIPS stuff seems interesting, though, so I'll try to catch up (and hopefully get ahead) over the weekend.
