2. a) Translate the following C++/Java code to LEGv8 assembly. Assume that integer variable i is assigned to register X19, variable sum is in register X20, and base address of doubleword array grades is in register X21. Add comments to your lines of code. (10%) sum = 0; for (i = 100; i > 0,1 -= 2) { sum = sum + grades ) 3 W b) Compile the following C++ statement to LEGv8 assembly. Assume that integer variable a is assigned to register X23. Add comments to your lines of code. (5%) a = proc(10) - 1
