thorpej 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.)

thorpej f22bd47b81 Use __sigaltstack14(), not sigaltstack(). 1997-12-05 02:09:49 +00:00
cgd 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).

jonathan 68a9b35134 Do a .cpload if compiling with PIC.
Examining  the .so output from binutils 2.8 and 2.8.1 shows the
	li.d	$f2, 4503599627370496e0
is (incorrectly?) emitted as GP-relative loads when PIC is in effect.

jonathan a70f22abe7 Back out previous revision, which is reported to break signal-handing
in the GNU awk in our tree.
Leave the change in but commented out, it may be a  ld.so problem.

jonathan a68c573b21 Rewrite from scratch. 1996-10-19 12:32:04 +00:00
jtc 41da409893 Added new macros:
SYSCALL_NOERROR(x):     Like SYSCALL except that "x" is a syscall
				that can never fail.

        RSYSCALL_NOERROR(x):    Like RSYSCALL except that "x" is a syscall
				that can never fail.

These macros simply call SYSCALL / RSYSCALL, and serve as placeholders
until an optimized implementation is done.

jonathan 945bd69ebd The old mips modf didn't work (pr 1048). This replaces it with
a version that does work on little-endian MIPS CPUs. Not tested on
big-endian MIPS; the "li.d" may be byteorder-dependent.

jonathan 946af1bccf Fix an old bug, whereby ASMSTR() was used before #including "SYS.h", where
