Need to convert this C code TO ARMV8 (in DS5)

Convert the below C code snippet to ARMv8 assembly code. Assume variables a, b, and c are stored in registers X20, X21, and X22 respectively and the array x is stored as a static array in the data section. Assume all the values are 64-bits and are unsigned integers. Do not use divide and multiply instructions in your code. Assemble, test, and simulate the assembly code using DS-5 simulator. Do not upload the entire DS-5 project. Only upload the assembly file (.S file) from the DS-5 project to Canvas, Comment your assembly code. (40 Points) a = b - C; X[2] = a + x[1]; x[a] X[2] + 4*x[b]; x[2*b] = x[a] + x[c/2]
