man feature_test_macros(7) specifies that _BSD_SOURCE and _SVID_SOURCE have
been deprecated in favor of _DEFAULT_SOURCE since libc 2.20. Specifying
either of the former is now equivalent to specifying just the latter. We add
this macro to conform to this standard, but do not add the compiler warning
to maintain full backwards compatibility with earlier version of glibc and
uclibc.

This syncs up <sys/reboot.h> with the GNU C library, see their
commit 1a09dc56. These constants are needed by init systems like
openrc.

This is a second attempt to fix a compilation failure involving a
missing struct timespec definition in some situation. Previous attempt
was following commit but it had undesirable side effects and was
reverted:
657c4a9d6c fcntl.h: fix a missing `struct timespec` definition
A similar issue was identified and reported in glibc [1], and the fix
was to include the timespec definition if __USE_XOPEN2K8 was defined. To
minimize the possible impact of this new fix, it was decided to not
replace __USE_ATFILE by __USE_XOPEN2K8 as glibc did, but to add an
additional OR condition on __USE_XOPEN2K8.

This reverts commit 657c4a9d6c2e649d86307f46ce9d5e44192f6e7a.
This breaks a lot of package cross-compilation as lvm, ruby,
ipsec-tools. :(

The included RPC implementation is ipv4 only.
Other C library projects have either deprecated the internal
RPC implementation (GNU C Library) or never implemented such
functionality (musl C Library). The latest rpcbind release (0.2.4)
checks for libtirpc and does not allow to be build with uClibc-ng
RPC without patching. The common use case for RPC nowadays is to
use rpcbind together with nfs-utils to provide NFS server or client
support to a system.
The included RPC implementation does create issues with duplicate
symbol failures when statically compiling with RPC enabled.

The header is not in sync with GNU libc and Linux kernel and
therefore produces compile errors with qemu-user (2.8.0).

If a source file is compiled with:
#define _XOPEN_SOURCE 700
#define _POSIX_C_SOURCE 200112L
Then including fcntl.h results in the following error:
In file included from fcntl.h:37:0,
from test.c:4:
sys/stat.h:371:54: error: array type has incomplete element type ‘struct timespec’
extern int futimens (int __fd, const struct timespec __times[2]) __THROW;
To fix that, we force the definition of struct timespec in fcntl.h when
__USE_XOPEN2K8 is defined. This mimics the behavior of glibc which
contains the following line in its io/fcntl.h header (included by
fcntlh.h):
#ifdef __USE_XOPEN2K8
# include <bits/types/struct_timespec.h>
#endif
This bug was spotted during the compilation of BoringSSL against uClibc.

This commit includes following features.
1. Support NPTL/TLS
2. Add libm function which is used to handle FP rounding and excpetions
(ex: fclrexcpt,fedisblxcpti,feenablxcpt... )
3. Add *context function for operating user context
(ex: setcontext,getcontext,makecontext... )
4. Change the return flow from signal handler
5. Cleanup of old code
The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1,
which are related to timing accuracy. (math and locale tests are disabled)

Remove __UCLIBC_HAS_OBSTACK__ as it isn't very uptodate and
maintained part. It shouldn't be required for any software and
mostly shipped with stuff which use it. (f.e. binutils-gdb)

Commit cee0b058fa0b4501b289a2da365182d60314d746 ("add aligned_alloc
required for latest gcc libstdc++") added the prototype of
aligned_alloc() to <stdlib.h>. This prototype contains
'__attribute_alloc_size__ ((2))', but this is not defined anywhere in
uClibc-ng.
This commit addresses that by adding the relevant definition in
<sys/cdefs.h>, borrowed from glibc.

As __UCLIBC_HAS_GETTEXT_AWARENESS__ is never defined, this is
mostly dead code. It is planned to integrate libiconv-tiny
and gettext-tiny into uClibc-ng after the next release, so
that more software packages can be used without modification.
Remove any _/_N macro usage.

Add support for Andes Technology NDS32 architecture.
See here http://www.andestech.com/en/index/index.htm for more
informaton. Verification of the port from an older uClibc
port was done on a sponsored AG101p board.
The testsuite only has 5 errors, three are related to
an existing bug in dlclose() with LT.old, also happening
on cris32 and m68k.
Failures to fallocate/posix_fallocate are unresolved.
Thanks to Andes Technology sponsoring the hardware and
being very helpful while doing the uClibc-ng porting.

Do it by following the trail of the existing commented code, which
implemented it by calling get_phys_pages() and get_avphys_pages().
This patch implements these two functions, which are also glibc
extensions.
Some program/libraries (e.g. libuv) assumes that sysconf(_SC_PHYS_PAGES)
works on linux and never check for -1, thus they report an insane amount
of memory.

Linuxthreads.new isn't really useful with the existence
of NPTL/TLS for well supported architectures. There is no
reason to use LT.new for ARM/MIPS or other architectures
supporting NPTL/TLS. It is not available for noMMU architectures
like Blackfin or FR-V. To simplify the live of the few uClibc-ng
developers, LT.new is removed and LT.old is renamed to LT.

Sync with GNU libc behaviour.

On systems where uClibc doesn't provide an arch specific byteswap.h,
we fall back on bits/byteswap-common.h. However, there is a bug
in this header in the __bswap_constant_64(x) macro. If, for example,
a double is passed, we get 'invalid operands to binary &' in which we
mismatch a 'double' and 'long long unsigned int'. The newer glibc
headers fix this and so we import them. Also, since the inclusion of
byteswap.h is not appropriate for assembly code, we guard a portion
of endian.h which uses byteswap.h from inclusion in any assembly.
This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big
endian PowerPC.

This is similar to this patch for GNU glob:
ff6ce3999db93a52d1cd22510f8508b660ddf54e.
The problem is that libiberty/obstack.c file checks for
_GNU_OBSTACK_INTERFACE_VERSION == _OBSTACK_INTERFACE_VERSION and elides
libiberty obstack implementation if there is already a compatible
implementation in libc. Therefore define should be set only when obstack is
actually selected, otherwise it is not possible to build binutils and gdb
with uClibc.

Some architectures do not provide the Linux header, so
packages which include a.out.h might fail.
Some discussions seen on the buildroot mailinglist.

The FR-V port is really broken, and I have no emulator
or hardware for this platform. I tried to get some hardware
from RedHat, who made the FR-V port initially. Unfortunately
Fujitsi didn't agreed to sent me some of their unused spare
hardware lying @RedHat. As I invested some time to get stuff compiled,
I decided to add the code and may be anytime later I can gain
access to some emulator or hardware.
GDB simulator for FR-V doesn't support booting Linux AFAIK.

getaddrinfo() does not implement IDN encoding, and always fail when
provided an IDN flag (e.g., AI_IDN) with EAI_BADFLAGS. Some packages
(such as the VLC media player) check for AI_IDN before they use it;
providing an unimplemented AI_IDN in the libc makes these package
fail. As a result they make calls to getaddrinfo() with AI_IDN that
always fail while they could have made successful calls without AI_IDN
instead.
Thus, do not define IDN flags: it is better not to compile rather than
to compile a code that always fail.

Implement single rtld_flags interpretation through all the
do_dlopen()/_dl_load_shared_library()/_dl_load_elf_shared_library()
calls chain.
This adds the ability to use the flags, passed to dlopen(), in all
underlaying functions and implement rtld_flags inheritance.
Saves a few bytes code.

Argp is an advanced support for parsing unix-style argument vectors.
In addition to the common getopt interface, it provides automatic
response
to `--help' and `--version' options and use of custom parser in
conjunction
with argp native option parser, among others.
Argp support is required by elfutils package and prelink.
In uClibc argp functionalities has been moved from C library to
libuargp.so
Further the libc.so linker script contains an AS_NEEDED entry so that
it doesn't need to link libuargp.so explicitely.
Disable argp test if feature disabled.
