7e49f8ba22 From Arne Juul <arnej@math.ntnu.no>: 
Explicilty reload the mips-ABIcall GOT/$gp  in cerror().
  cerror() gets called from outside libc (e.g., from libposix's rename(),
  and if we don't load $t9, cerror() makes wild references using
  the libposix $gp and coredumps.

bedc7b48df Add syscall stubs for __vfork14(). These are basically copies of Ovfork.S 
with the syscall numbers changed.

Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers).  __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns.  (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)

eb96023de7 Quick fix to repair runtime link problem with libc - "SYS_sigaltstack 
undefined".  The sigaltstack structure layout didn't actually change on
the sparc, so just change the syscall name.  A better fix would probably
be to replace the direct system call with a function call to the libc
sigaltstack().

4d7e773266 A foolish consistency... gen, net, and string all get MD sources

e6cb27b508 ieee.h and ldexp.c taken from the powerpc port, for the benefit of 
68040 and 68060 owners.
With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp()
doesn't use excessive amounts of system cpu time.
Without any of those defines, the normal assembler version using FSCALE is
included, for the benefit of M68020 and M68030 users, or M68040/M68060 users
where the ldexp performance is no bottleneck.
[Its not yet worked out how to include both library versions in a binary
distribution, but you can build your own from source now if you need it.]
For details, look at PR 3105.

530ba70aa3 New implementations of strcmp() and strncmp(). 
This code uses subb instead of cmpb to compare chars.  When they are
not equal, the function's return value is computed by sign extending
the difference.  The basic idea was contributed by Hiroshi Horitomo
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3223, but his implementation
used additional instructions to compute the return value.

Also, the series of insns used to compare one pair of characters has
been unrolled 4 times.  This helps the 680[23]0, where the cost of a
taken branch is significantly more than that of a not-taken branch.

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.

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.
