PROBLEM 6

A) Translate last two ARMv8 assembly instructions to 32-bit binary machine code. Give your answer in hexadecimal. Assume that the code for .GE is 0xA.

loop: ADD X9,X9,8

LDUR X19,[X9,#0]

CMP X19,X0

B.GE loop

Instruction CMP: 0x _______________

Instruction B.GE: 0x _______________

B) What value is left in X0 after the following code is run (Remember ARMv8 is big endian)? The label func located at 0x400040.

func: ADRP X1,func

ADDI X1,X1,:lo12:func

ORR X2, XZR, 0x2

ADD X10, XZR, XZR

ADD X0, XZR, XZR

STUR X1, [X2, 0]

LDURB X0, [X2, 7]
