Your Answer for Question 1:
To avoid saving and restoring a register whose value is never used, which might happen with a temporary register, MIPS software ofers two classes of registers.
- $t0-$t9:10 temporary registers not preserved by the callee on a procedure call.
- $s0-$s7:8 saved registers that must be preserved on a procedure call.

This simple convention reduces spilling.

Your Answer for Question 2:
A programming language that does not permit recursive procedures need not allocate frames on a stack. In a nonrecursive language, each procedure’s
frame may be statically allocated since only one invocation of a procedure can be active
at a time.
We would often get "stack overflow" error.

Your Answer for Question 3:
The reading was interesting, especially nested procedures.
