Problem $2.$ Using the disassemble command under gdb$,$ examine the first five instructions of

recmul $($ignoring the endbr$64$ instruction$).$

$1$

a$.$ Compare these instructions to the first five instructions of recexp. What do you notice?

b$.$ What are these instructions doing? $($Hint: recall that the parameters to each function are

passed in registers $\%$rdi and $\%$rsi.$)$

c$.$ Whydoes the compiler generate this code? $($Hint: look at the instructions before the recursive

call in each function.
