Fix the [-Warray-parameter=] warning for __sigsetjmp generated by GCC 11 and
later GCC versions:
|
| warning: argument 1 of type 'struct __jmp_buf_tag *' declared as a pointer [-Warray-parameter=]
| extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROWNL;
| ...
| note: previously declared as an array 'struct __jmp_buf_tag[1]'
| extern int __sigsetjmp (struct __jmp_buf_tag __env[1], int __savemask)
|
Use the same fix as in glibc. The fix is to move the struct __jmp_buf_tag
definition to a separate bits/ header so it can be included in
pthread.h, to allow to use an array (as in setjmp.h) rather than a pointer
in the declaration.

issue with gcc 12
The current definition of __WCHAR_MIN and __WCHAR_MAX are only correct
when wchar_t is an int. This is not the case on ARM/AArch64 where
wchar_t is an unsigned int, or some other architectures where wchar_t
is a long.
The current incorrect definition causes a build issue for example when
building mpd, which uses boost, with gcc 12.x:

This issue was fixed in glibc in 2013, see bug report
https://sourceware.org/bugzilla/show_bug.cgi?id=15036, and upstream
commit
https://sourceware.org/git/?p=glibc.git;a=commit;h=052aff95782fefe9c63566471063e8b20836bfb8.
Since the i386-specific definition of __WCHAR_MIN and __WCHAR_MAX was
also removed at the same time in glibc, we do the same as part of this
commit.

This macro exists since Linux 2.6.25 [1] and is defined in glibc
since 2.14 [2] for sparc and most supported architectures.
RLIMIT_RTTIME has been added later for mips [3] and alpha [4].
For example, RLIMIT_RTTIME is needed to build qemu 7.0.0 with
Linux user-land emulation support [5].

Rename various spare fields in structs to include a namespace
This should avoid accidental clashes with uses of the __unused symbol
in upstream projects. eg currently it causes a compile error in dhcpcd 8.x
due to their re-use of the __unused symbol as a macro
This follows the style of glibc which does something equivalent

The function towlower doesn't work with locales different from C.
Issue was introduced in commit: 8cde3a9bf2856dcb9a759dec7ecb04a68e712254
Call to setlocale is needed for correct generation of the table uplow_diff.
Otherwise you receive compile time error "range assumption error" after
uncommenting the call.
Similar problem described here:
http://lists.uclibc.org/pipermail/uclibc/2015-March/048852.html
This commit fix the problem by using int32_t values.

Commit 251a3c19cb "sleep: employ __USE_EXTERN_INLINES (with necessary fixes)"

1. __USE_EXTERN_INLINES forcibly enabled build fails

...
2. libuargp wrongly contains __cmsg_nxthdr/__sigismember/__sigdelset/__sigaddset
global symbols on platforms which includes signal.h from sys/procfs.h
As result, static linking will fail:

We have to partially revert 251a3c19cb to fix problems above. It is
safe to do this after commit
162cfaea20 *: inline constant __sig{add,del}set and __sigismember
since we are able to use new inlines from within libc and leave the
rest of world(__USE_EXTERN_INLINES) equal to glibc now.

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.

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.

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.

uClibc doesn't define signal info for the SIGSYS signal which is issued
in case of hitting a syscall prohibited by seccomp.
This is sad as it makes debugging seccomp filter policies impossible on
some architectures (at least ARM and PowerPC, maybe also others) which
do not coincidentally set si_value.sival_int as the syscall number.
To fix this, import the definitions and macros needed from glibc.
