Subject: [9fans] bcopy in APE

Finishing out my network stack redesign in netbsd, I glanced
at the source of the bcopy function. The BSD implementation,
found at /sys/lib/libsa/bcopy.c, increments while copying
octets if arg1 is greater than arg2.

However, the plan9 APE implementation of bcopy (found at
/sys/src/ape/lib/ap/gen/memmove.c) decrements.

My question is, why does the function need to increment or
decrement at all? And if there is a specific reason, why does
plan9's implementation do it opposite of the netbsd? I really
have no idea why the if(x < y) clause is needed.

Comments?
