Question

Write a single C statement that corresponds to the two LEGv8 assembly instructions below.

A. ADD R1, R2, R3
B. MOV R4, #10
C. CMP R5, R6
D. STR R7, [R8]

Answer 1

A single C statement that corresponds to the LEGv8 assembly instruction STR R7, [R8] is '*R8 = R7;' which stores the value from R7 into the location pointed to by R8.

Step-by-step explanation:

The student is asking how to write a single C statement that corresponds to the given LEGv8 assembly instructions. From the provided options, the correct matching C statement for STR R7, [R8] is:

*R8 = R7;

This line of C code is performing the same operation as the assembly instruction, which stores the value from register R7 into the memory address pointed to by register R8. It's important to note that the other given assembly instructions correspond to different operations and therefore would translate to different C statements.
