4.100% which of the following segments of C code best describes what the following MIPS assembly code does? (Note: oddly, unlike nearly every programming language, MIPS add detects integer overtloW -- SO always use addu as this code does.) you really should $to, x $t1, 0(Sto) $t2, y $t3, 0 (St2) $t1, $0, 12 $t1, $t1, $t3 $t1, 0($t0) lw 11 e 12 addu SW 0 x=x+y ; 0 if (x-=0) { x=x+y; } 0 if (x!=0) { x=x+y; } 0 while (x==0) { x=x+y; 0 while (x1=0) { x=x+y; } }
