e1e9dd27c5 Copy up bcopy.S and memcpy.S. 1998-02-22 06:46:55 +00:00

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.)

4d7e773266 A foolish consistency... gen, net, and string all get MD sources 
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).

7b8ed4c70b update for new <machine/asm.h> and generally clean up: 
rename SYSCALL_NOLABEL as CALLSYS_ERROR (for consistency with CALLSYS_NOERROR
    now in asm.h), and implement it using CALLSYS_NOERROR.
reimplement SYSCALL, RSYSCALL, and PSEUDO to use the appropriate macros.
implement SYSCALL_NOERROR and RSYSCALL_NOERROR to do the same thing as
    SYSCALL and RSYSCALL, but without the error checking/handling.

7a8e7b22a1 deal properly (i hope!) with registers' upper 32 bits, when doing 
32-bit division and remainder.  Sometimes, when optimizing, they could
have been different than previously expected (and could have caused
hokey results).
