Question

For the whole question, pseudo-instructions are not allowed except “j target_label”
and “jr ra”. One suggestion for assembly programming problems is that you can include
comments to one or a block of instructions.

Consider a RISC-V assembly function func1. func1 has three passing
arguments stored in registers a0, a1 and a2, uses temporary registers t0-t3 and
saved registers s4–s10. func1 needs to call func2 and other functions may call func1
also. func2 has two passing arguments stored in registers a0 and a1, respectively. In
func1, after the program returns to func1 from func2, the code needs the original
values stored in registers t1 and a0 before it calls func2.

(a) How many words are the stack frames of function func1?
(b) Indicate which registers are stored on the stack of func1.
