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.

* Add correct $NetBSD$ headers everywhere.
...
* Remove $Id$ headers.
* Support LIB_SCCS in all files.
* Use local labels where ever possible.
* Use cpufunc.h instead of __asm__ when possible.
* Access labels with _C_LABEL and _ASM_LABEL.
* Always set errno by calling cerror.
* No more FRAME/EMARF.
* No more SVC, use SYSTRAP instead.
* Use "$Masqueraded: as XXX $" to show e.g. memcpy compiled as bcopy.
* Rewrite vfork to work even whith a "real" vfork system call.
* Make cerror take care of _REENTRANT.

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.

and memmove(), by compiling with the appropriate options.

fields so that the mask and sticky bits are the same.
