Pass via r4 the rtld finalizer
_dl_fini to the user application. This will be the 6^ arg of
__uClibc_main and will be registered with 'atexit'.
In this way the dynamic linker will be able to call destructors
defined within the loaded DSOs.

brk.c:(.text.__GI_sysconf+0xd4): undefined reference to `clock_getres'

Some of the code is functionally identical before and after, but for now
I'm just mechanically reverting the entire mess.
|
|
|
|
|
|
For now, a straight revert; we can decide later wheter we want to do something
more.

no libc_hidden_def exists for the function.

The spill routine to flush all windowed registers was missing a 'mov'
instruction.

__uc_malloc calls in getnetent.c, so we must retain the include and
libc_hidden_proto).

since posix_openpt lives in getpt.c it has to stay there unconditionally.

Fixes compilation error for defined UCLIBC_HAS_PTY && !defined UNIX98PTY_ONLY
which need both __libc_ptyname1 and __libc_ptyname2 for ptsname_r().

- ptsname_r depends on UCLIBC_HAS_PTY just like ptsname()

definition. I seems to produce spurious warning:
libc/inet/resolv.c:1549: warning: 'visibility' attribute ignored on non-class types
(seems like gcc bug)
and it is not really needed - attribute_hidden was already
specified in function _declaration_ so it is not necessary here.
No code changes (verified with objdump).

SIGPIPE handler was attempting to re-acquire an already taken lock.
While at it, stop checking for sigaction failure which is not possible here.

we were closing a FILE, but did not record that fact by setting
a variable to NULL, and then we used it for reading!
While at it, small reduction in bss.

- tidy up PTHREADS_DEBUG_SUPPORT by using per-target STRIP_FLAGS for the few
This fixes the spurious rebuilds bernd and vda were seeing with libpthreads.

The obsolete functions bcopy, index, etc. are not supposed to be used within
uClibc itself. Hence, there is no libc_hidden_def for them, but the previous
patch did not just move libc_hidden_protos, it also added new ones for the
legacy functions. As a result, programs which use these functions can no
longer link with uClibc.
This fixes it by removing the unnecessary libc_hidden_protos. I've also
removed all inclusions of <strings.h> from uClibc source files: since we
define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not
need to duplicate the libc_hidden_proto block in <strings.h>.

1. names with two consecutive dots are not valid
2. if name ends with a dot, dont try appending search domain(s)
alos a few small optimisations are here.

The bug: this blocks in syslogd is stopped:
#include <syslog.h>
int main() {
int i;
for (i = 0; i < 10000; i++)
syslog(LOG_INFO, "Testing, disregard....................");
return 0;
}
Fix: set O_NONBLOCK on fd to "/dev/log".
Other fixes: do not try to write to fd -1, do not spin forever or EAGAIN,
use constant sockaddr instead of recreating identical one each time,
eliminate one intermediate function (SUGPIPE sig handler),
use smallints where appropriate, add a few comments.
