Write a hypothetical RISC$-$V assembly language program consisting of $3$ instructions

that would exhibit high temporal locality in the instruction cache. Note that the program

need not do anything meaningful Assuming the first instruction is at PC $=100,$ show the

address trace of the first thirst instructions executed in the program.

Problem $2(10$ points$)$

Explain why a compiler might make the following optimization to a C program. You must

be very specific, otherwise you will get ZERO credit.
