Question: Q1 Write more efficient code consisting of two ARM assembly instructions that are equivalent to the following instructions sequence: MOV r1, r1, LSR #2 ADD

Q1

Write more efficient code consisting of two ARM assembly instructions that are equivalent to the following instructions sequence:

MOV r1, r1, LSR #2

ADD r1, r3, r1

MOV r4, r4, ROR #7

SUB r4, r6, r4

Q2

Write a single ARM assembly instruction which will multiply an integer stored in r8 by 7 and store the product in r5.

(Note: you cannot use any of the explicit multiplication instructions; MLA, MUL, UMLAL, UMULL, SMLAL, or SMULL).
