What libc implementation are you based on? I'm wondering if if would make more sense to replace memcpy entirely for the whole system in case the native implementation is not as good. uClibc, for example, has an optimized routine for memcpy: http://sources.busybox.net/index.py/trunk/uClibc/libc/string/arm/_memcpy.S?revision=22064&view=markup Daniel _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
