davidg 95/12/27 10:47:46 Modified: lib/libc/i386/string bcopy.S memmove.S Log: 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 1.3 +8 -6 src/lib/libc/i386/string/bcopy.S 1.3 +8 -6 src/lib/libc/i386/string/memmove.S
