fredette 3085bd52b8 On the 68010, we are forced to do bytewise compares
and copies if the two addresses aren't of the same
evenness.

jtc d46e665a16 Faster versions of bcmp(), bcopy(), bzero(), and memset().
The implementation of these functions is losely based on the original
BSD code plus versions I was working on which would yeild code tuned
for a particular m68k or coldfire family cpu, code space or run time
efficiency, etc. depending on the values of various macros.

My original code was intended for use in OS-less embedded systems.
Because NetBSD can not benefit from the considerable complexity, I've
removed the extraneous preprocessor goop.  The resulting code is tuned
for the '020 - '060.  It will not function on the '000 or coldfire.

jtc f42ebd4897 #include <machine/asm.h> instead of "DEFS.h" 1997-01-04 03:26:18 +00:00
jtc 48030a80ae Use jCC instead of bCC, as the assembler will then use the (smaller,
faster) byte-displacement form of the instruction if the offset will
fit.  This happens to be all occurances in this case, so I could have
used bCCs.  However, a quick survey of the rest of NetBSD's m68k code
showed that jCC was used in similar cases.  I did the same to be
consistant.

thorpej ed63b163c8 Fix a brain-o by me; if I'm going to use stuff in <machine/asm.h>, I better
darn well include it in the right place.  "Hello, McFly!"
