37 * r5 - Accumulated sum value
43 * This is the internet (IP, TCP) checksum algorithm, which is the 1s-complement sum
47 * final sum is folded down to 16 bits. On 32-bit machines we use "adde", which is
50 * all 64-bits into a 16-bit sum at the end. We cannot use "adde" on 64-bit sums,
52 * is set on the low 32-bits of the sum.)

396 add r8,r8,r9 ; now r8 is 64-bit sum of the four accumulators
399 srdi r7,r8,32 ; get upper half of 64-bit sum
