davidg 95/12/27 10:54:53 Modified: sys/i386/i386 support.s Log: Update bcopyb & bcopy to reflect changes I made in the libc version of bcopy: Be smarter about handling overlapped copies and only go backwards if it is really necessary. Going backwards on a P6 is much slower than forwards and it's a little slower on a P5. Also moved the count mask and 'std' down a few lines - it's a couple percent faster this way on a P5. Revision Changes Path 1.30 +12 -7 src/sys/i386/i386/support.s
