The vfork() wrapper defined in libpthread, that's used to run
pthread_atfork()-registered handlers, is not only a very bad idea,
it's broken and useless. Here's the rationale:
[---------snip----------]
Since the implementation as it stands is broken (linking a program
that vfork()s and exec()s on the child and wait()s on the parent works
unless you happen to link with libpthread), and I can't think of
any workable solution, I suggest that we simply remove the vfork()
overrider in the non-MMU case. Yes, we might lose some small amount
of functionality here, but it's not like people running uClinux expect
anything resembling actual fork() to work.

Because variables are linked to fixed registers, there is a problem in :
(*__errno_location())=(-_r0);
As __errno_location() uses r0 to return the address of the errno location,
the negated address will be assigned instead of the error code.
Attached patch will resolve this.

This code in uClibc would attempt to set the default facility if
none was specified. Except none being specified is 0, which is
also LOG_KERN, therefore klogd could never get kernel messages
logged as LOG_KERN.

This patch arranges for the .so files in say /usr/lib to be soft links
to ../../lib, instead of to /some/arbitrary/pathname/lib. This
enables seamless relocation of a toolchain containing the development
and run time trees in a sys-root.

I added this function after I posted the last version of the FR-V
patch. Add syscall.c.

instead. Based on an initial patch from Tobias Anderberg, but reworked. I
asked Tobias to look into doing something more like what is done in busybox,
but that proved to be a pain.
One possible concern is that these buffers will probably show up as
memory leaks i.e. with valgrind. Perhaps we should add in an atexit
call to free this memory right after we allocate it?

Hi
I just noticed that gcc has an "b"(Address base register) operand that
will match all "r" registers but r0. It is a better fix then adding
r0 to the clobber list.
What do you think?

error.c file still needs work.

Bug fix: gethostbyname_r checked errno without first setting it to a

This patch adds code to uClibc to support a new ABI designed for the
FR-V architecture, that enables text segments of executables and
shared libraries to be shared by multiple processes on an OS such as
uClinux, that can run on FR-V processors without an MMU.
Patches for binutils and GCC have just been posted in the
corresponding mailing lists. The binutils patch was approved,
but there's one additional patch pending review, that I posted
this week. An updated GCC patch will be posted to
gcc-patches@gcc.gnu.org as soon as I complete testing (I used a
known-good compiler to test the uClibc patch below).
Since the existing dynamic loader code didn't support independent
relocation of segments, it required changes that were somewhat
extensive. I've added a number of new machine-specific macros to try
to keep the platform and ABI-specific details outside the generic
code. I hope this is not a problem.

While testing the FR-V code with GCC mainline, I ran into some
problems in the RPC code. It relies on a GCC extension that is no
longer available, namely, the result of a cast is no longer considered
an lvalue.
This patch enables the code to compile. I haven't been able to test
RPC though, especially in a multi-threaded environment.
