bcd75f16cb Duh, call the clone's entry point w/ jal, so that when it returns,
it returns to the correct $ra (not the parent's!!).

af83a97717 Add special treatment of shmat(2).
On m68k ELF calling standard (__SVR4_ABI__), if a function
returns a pointer, the return value should go to a0 as well as d0.

de9e80b40f Missed in previous: replace the previously used _brk label with an ordinary
local label; problem noticed by Matthias Drochner.

5510a708c4 Make __cerror be LEAF_NOPROFILE. I relies upon having v0 and v1 be unchanged

30dca7f7db Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d
in their respective header files).  Add PSEUDO stubs for the old versions
of these system calls.

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

5af7e7a902 Change references to end' to _end' as not to invade (or being invaded by)
the user's name space.

6348b7d5b5 * On architectures using ELF, and conditionally on those in transition, rename
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

efd37a7da8 Warn about references to the compatibility vfork() (i.e. the vfork() with
the 4.4BSD non-shared-address-space semantics), and direct the user to
include <unistd.h> to generate the correct reference.

This warning isn't about an ABI compatibility issue, but the new vfork() is
considerably faster.

e644246e6a Warn about references to the compatibility() sigaction(), sigpending(),
sigprocmask(), sigreturn(), and sigsuspend(), and direct the user to
include <signal.h> to generate the correct reference.

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.)
