Hello,
the ppc memset, memcpy, memmove from string.h didn't work for me. Busybox-Vi
always got a segfault. I only debugged the memset.c. Memmove and memcpy were
replaced by simpler functions.
The failure is in the "align" section. In the case that only n==1 characters
had to be replaced and for an aligned adress there are remaining rem==3 spaces
with n=n-rem; an overflow occurred.
I'm running a MPC5554.
greetings
Erik
