Assume that Q is an array of 32-byte records and the VAL field is in the first 4 bytes of each record. Using x86 code, we can compile this program fragment as follows:

MOV ECX,1 ;use register ECX to hold I

LP: IMUL EAX, ECX, 32 ;get offset in EAX

MOV EBX, Q[EAX] ;load VAL field

ADD S, EBX ;add to S

INC ECX ;increment I

CMP ECX, 101 :compare to 101

JNE LP ;loop until I  100

Interpret them.

Answer rating: 100% (QA)

This program makes use of the IMUL instruction which multiplies the second operand by the immediate ... View the full answer
