Consider the following code:

LDR r1,[r6] ;Load r1 from memory. r6 is a pointer
ADD r1,r1,#1 ;Increment r1 by 1
LDR r2,[r6,#4] ;Load r2 from memory
ADD r2,r2,#1 ;Increment r2 by 1
ADD r3,r1,r2 ;Add r1 and r2 with total in r3
ADD r8,r8,#4 ;Increment r8 by 4
STR r2,[r6,#8] ;Store r2 in memory
SUB r2,r2,#64 ;Subtract 64 from r2
