adb7eb514d sigaction() that calls the compat syscall (jonathan forgot to commit this). 1998-09-28 19:01:28 +00:00

0c47ce2246 mips libc stubs for sig*14 signal API (128bit sigset_t), 
plus backward-compatibility  for the old 1.3 libc entrypoints.

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.)

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).

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.

Leave the change in but commented out, it may be a  ld.so problem.

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.

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.
