21110867b5 Goodbye to bcmp.S, bcopy.S, and bzero.S. They are defined as macros in 
sys/systm.h.

6fe2633df0 Remove bcmp.S and bzero.S from list. They were doing nothing but wasting 
kernel bits for a long time (2 years?).

5e7e19ec12 Xscale-optimised mem* functions, contributed by Wasabi Systems. 
(Note: memcmp/memset improvements also benefit non-Xscale).

memcmp()  - Compare 32-bits at a time if possible. Special-case 6-byte
            comparisons, for the benefit of the network stack.

memset()  - More loop unrolling, plus use of 'strd' instruction,
            results in > 100% speedup on Xscale.

memcpy()  - Big-endian support, unrolled loops, 'strd/ldrd/pld', plus
            special-cases for very common length/alignment combinations
            (at least in the kernel). Benchmarks show ~50% improvment on
            Xscale.

memmove() - Big-endian support. Use fast memcpy(), above, if the regions
            don't overlap. Otherwise unchanged.

b2566d8735 Provide a strtoul() implementation based on the one in libc instead of the 
totally different version that was here.  This version, of course, has an
BSD license on it while the old one did not.  This one also compiles down
to tighter code--the smaller the better for libkern & libsa.

c327a133c6 Significantly faster memcpy/memmove/bcopy and memset/bzero 2003-04-15 22:49:50 +00:00

bfc4be13a6 When MEMCOPY is defined, don't bother checking if a backwards-copy is 
required. That's what memmove() is for.

This should fix port-powerpc/16889. The backwards copyin can confuse
uiomove/genfs_getpages, resulting in corruption of files written over NFS.

6576c49b48 Add an assembler version of strcmp, based on example code from the ARM 
ARM.  As an example of the performance difference that this provides
a Dhrystone score on my Shark goes from 213k to 261k.

appropriate places.
