cgd ec1f804952 add back RCS Id which I accidentally deleted. 1998-01-22 20:05:20 +00:00
cgd 193c1d2147 (1) make sure targets are built in a parallel-make-safe way 
(2) make sure softfloat.po is compiled with the right profiling
    flag (-pg), and softfloat.so is compiled with the right
    PIC flags (${CPICFLAGS}).

cgd ecb2fd7aad define INLINE to be "static inline" rather than "extern inline", so that 
if this code is compiled without optimization the not-inlined functions
will be included (statically) in the object files, and now show up
as undefined references.

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.)

mark 0053558a70 Fix a glaring bug in the assembly stubs for memcpy() and memmove() that 
meant the src address was being returned rather than the dst address.
Spotted by Chris Demetriou.

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).

mark a2b5e07612 Include memmove.S in the list of sources. 1997-10-18 02:28:25 +00:00
mark fd06e9f4e6 Use the ASENTRY() macro for the declaration of cerror. 1997-10-17 19:57:17 +00:00
mark fb4d5f58af Fix extra 'S' character typo that resulted in the condition codes being 
incorrectly internally on certain divides.
Handle the case where the internal result appears negative. This condition
can occur when dividing MIN_INT by certain values.
Raise an exception on divide by zero.

mycroft c9ec05f4b2 Treat reboot() like a normal system call. From PR 2458. 1996-11-11 13:41:08 +00:00
jtc 7228c89e17 Added new macros: 
SYSTRAP(x):             Expands to the code used to call syscall x.
				This is used to simplify other 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.
