statfs() is a Linux-specific function. When building without
UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in
include/sys/statfs.h is unmatched with libc_hidden_def(statfs)
in libc/sysdeps/linux/common/statfs.c, leading to a compile
error. This patch fixes this, as well as adds statfs() to the
list of Linux-specific functions in extra/Configs/Config.in.

As most of these architectures either does not compile or embedded
hardware is difficult to get, I disable them for now.
I do not remove the existing code and hope to enable many
of them in the future, but not for 1.0.

There is a NPTL port of uCLibc for c6x, but it doesn't work
with uClibc master. May be someone with real hardware could
sync it. Unfortunately I got no respone from Aurelien and
no response on the mailing list.
|

When NPTL is available for an architecture just allow the use of it.
If NPTL is not available for an architecture, allow to choose between
LT and LT.old. This minimizes misconfiguration of threading library.
|

disabling this results in non-working toolchain building, so
better do not allow anyone to disable it.

We add the Linux-specific function fallocate() which allows the user to
directly manipulate allocate space for a file. fallocate() can operate
in different modes, but the default mode is equivalent to posix_fallocate()
which is specified in POSIX.1.
Recent releases of e2fsprogs 1.42.11 and above expect fallocate64() to be
available.

For this port, I would like to give due credit to:
- Folks from Codito technologies (Sameer, Amit, Kanika, Ramana,...)
who did the very first port
- ARC UK from 2007-2009 (Joern, Irfan, Khurram, Phil...
- Late Brendan Kehoe (may he RIP)

You can set these yourself in your CFLAGS, and our list is incomplete
and pointless (we agreed some time ago to stop doing this).
We keep around CONFIG_[3456]86 because it is used to select between
different optimized subdirs of handcoded assembly.
Also take this opportunity to up the default to i686. If you're using
an older cpu, then you can handle changing this yourself.

Meta cores are 32-bit, hardware multithreaded, general purpose, embedded
processors which also feature a DSP instruction set, and can be found in
many digital radios. They are capable of running different operating
systems on different hardware threads, for example a digital radio might
run RTOSes for DAB decoding and audio decoding on 3 hardware threads,
and run Linux on the 4th hardware thread to manage the user interface,
networking etc. HTPs are also capable of running SMP Linux on multiple
hardware threads.

Since NPTL port to an ARCH can be non-trivial, we must allow the legacy
pthread lib to be built for the common-generic syscall ABI
Note that only linuxthreads.old is allowed, since "newer" linuxthreads
relies on sysctl which the ABI no longer provides.

Linuxthreads(old and new) need deprecated syscalls to build. Existing
architectures support these system calls but new architectures don't.
This symbol has no functional change apart from hidding the Linuxthreads
symbols from arches that don't support them.

Touch signals only if DODEBUG is enabled.
Make the signal selection dependent on DODEBUG, as last resort use SIGKILL.
Use internal functions with less arguments, some savings.
Fix a warning about unused argument.
Do not use openlog/closelog, while there remove their hidden versions.

The latest POSIX spec introduces a "m" character to allocate buffers for
the user when using scanf type functions. This is like the old glibc "a"
flag, but now standardized. With packages starting to use these, we need
to implement it.
for example:
char *s;
sscanf("foo", "%ms", &s);
printf("%s\n", s);
free(s);
This will automatically allocate storage for "s", read in "foo" to it,
and then display it.
I'm not terribly familiar with the stdio layer, so this could be wrong.
But it seems to work for me.

This is based on Ulrich Drepper's implementation in GLIBC, but hacked up to work
in uClibc. The differences from the GLIBC version are as follows:
- b64_from_24bit() has been converted into a macro
- Usage of GLIBC-isms (such as libc_freeres_ptr) have been removed
It is enabled by the UCLIBC_HAS_SHA256_CRYPT_IMPL configuration symbol. You must
have UCLIBC_HAS_CRYPT_IMPL enabled as well.
