In glibc 2.17, the functions clock_getcpuclockid, clock_getres,
clock_gettime, clock_nanosleep, and clock_settime were moved from
librt.so to libc.so, leaving compatibility stubs behind. Now that the
dynamic linker no longer insists on finding versioned symbols in the
same library that originally defined them, we do not need the stubs
anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases
for most of the functions anymore either. (clock_gettime still needs
one.) For ports added before 2.17, libc.so needs to provide two
symbol versions for each, the default at GLIBC_2.17 plus a compat
version matching what librt had.
While I'm at it, move the clock_*.c files and their tests from rt/ to
time/.

This patch refactor sigcontextinfo.h header to use SA_SIGINFO as default
for both gmon and debug implementations. This allows simplify
profil-counter.h on Linux to use a single implementation and remove the
requirements for newer ports to redefine __sigaction/sigaction to use
SA_SIGINFO.
The GET_PC macro is also replaced with a function sigcontext_get_pc that
returns an uintptr_t instead of a void pointer. It allows easier convertion
to integer on ILP32 architecture, such as x32, without the need to suppress
compiler warnings.
The patch also requires some refactor of register-dump.h file for some
architectures (to reflect it is now called from a sa_sigaction instead of
sa_handler signal context).
- Alpha, i386, and s390 are straighfoward to take in consideration the
new argument type.
- ia64 takes in consideration the kernel pass a struct sigcontextt
as third argument for sa_sigaction.
- sparc take in consideration the kernel pass a pt_regs struct
as third argument for sa_sigaction.
- m68k dummy function is removed and the FP state is dumped on
register_dump itself.
- For SH the register-dump.h file is consolidate on a common implementation
and the floating-point state is checked based on ownedfp field.
The register_dump does not change its output format in any affected
architecture.
I checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
arm-linux-gnueabihf, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu,
powerpc64-linux-gnu, and powerpc64le-linux-gnu.
I also checked the libSegFault.so through catchsegv on alpha-linux-gnu,
m68k-linux-gnu and sh4-linux-gnu to confirm the output has not changed.

The resolution of C floating-point Clarification Request 25
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2397.htm#dr_25> is
that the totalorder and totalordermag functions should take pointer
arguments, and this has been adopted in C2X (with const added; note
that the integration of this change into C2X is present in the C
standard git repository but postdates the most recent public PDF
draft).
This patch updates glibc accordingly. As a defect resolution, the API
is changed unconditionally rather than supporting any sort of TS
18661-1 mode for compilation with the old version of the API. There
are compat symbols for existing binaries that pass floating-point
arguments directly. As a consequence of changing to pointer
arguments, there are no longer type-generic macros in tgmath.h for
these functions.
Because of the fairly complicated logic for creating libm function
aliases and determining the set of aliases to create in a given glibc
configuration, rather than duplicating all that in individual source
files to create the versioned and compat symbols, the source files for
the various versions of totalorder functions are set up to redefine
weak_alias before using libm_alias_* macros to create the symbols
required. In turn, this requires creating a separate alias for each
symbol version pointing to the same implementation (see binutils bug
<https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is
done automatically using __COUNTER__. (As I noted in
<https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might
well make sense for glibc's symbol versioning macros to do that alias
creation with __COUNTER__ themselves, which would somewhat simplify
the logic in the totalorder source files.)
It is of course desirable to test the compat symbols. I did this with
the generic libm-test machinery, but didn't wish to duplicate the
actual tables of test inputs and outputs, and thought it risky to
attempt to have a single object file refer to both default and compat
versions of the same function in order to test them together. Thus, I
created libm-test-compat_totalorder.inc and
libm-test-compat_totalordermag.inc which include the generated .c
files (with the processed version of those tables of inputs) from the
non-compat tests, and added appropriate dependencies. I think this
provides sufficient test coverage for the compat symbols without also
needing to make the special ldbl-96 and ldbl-128ibm tests (of
peculiarities relating to the representations of those formats that
can't be covered in the generic tests) run for the compat symbols.
Tests of compat symbols need to be internal tests, meaning _ISOMAC is
not defined. Making some libm-test tests into internal tests showed
up two other issues. GCC diagnoses duplicate macro definitions of
__STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added
an appropriate conditional and filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue.
On ia64, include/setjmp.h ends up getting included indirectly from
libm-symbols.h, resulting in conflicting definitions of the STR macro
(also defined in libm-test-driver.c); I renamed the macros in
include/setjmp.h. (It's arguable that we should have common internal
headers used everywhere for stringizing and concatenation macros.)
Tested for x86_64 and x86, and with build-many-glibcs.py.

resulted in <asm/socket.h> indirectly including <linux/posix_types.h>.
The latter is not namespace-clean for the POSIX version of
<sys/socket.h>.
This issue has persisted across several Linux releases, so this commit
creates our own copy of the SO_* definitions for !__USE_MISC mode.
The new test socket/tst-socket-consts ensures that the copy is
consistent with the kernel definitions (which vary across
architectures). The test is tricky to get right because CPPFLAGS
includes include/libc-symbols.h, which in turn defines _GNU_SOURCE
unconditionally.
Tested with build-many-glibcs.py. I verified that a discrepancy in
the definitions actually results in a failure of the
socket/tst-socket-consts test.

With commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c ("ld.so:
Support moving versioned symbols between sonames [BZ #24741]"), the
dynamic linker will find the definition of vfork in libc and binds
a vfork reference to that symbol, even if the soname in the version
reference says that the symbol should be located in libpthread.
As a result, the forwarder (whether it's IFUNC-based or a duplicate
of the libc implementation) is no longer necessary.
On older architectures, a placeholder symbol is required, to make sure
that the GLIBC_2.1.2 symbol version does not go away, or is turned in
to a weak symbol definition by the link editor. (The symbol version
needs to preserved so that the symbol coverage check in
elf/dl-version.c does not fail for old binaries.)
mips32 is an outlier: It defined __vfork@@GLIBC_2.2, but the
baseline is GLIBC_2.0. Since there are other @@GLIBC_2.2 symbols,
the placeholder symbol is not needed there.

The kernel is evolving this interface (e.g., removal of the
restriction on cross-device copies), and keeping up with that
is difficult. Applications which need the function should
run kernels which support the system call instead of relying on
the imperfect glibc emulation.

No 32-bit system call wrapper is added because the interface
is problematic because it cannot deal with 64-bit inode numbers

Linux 5.1 adds missing syscalls to the syscall table for many Linux
kernel architectures. This patch updates the kernel-features.h
headers accordingly. __ASSUME_DIRECT_SYSVIPC_SYSCALLS is not updated
because of the differences between new and old syscalls described in
<https://sourceware.org/ml/libc-alpha/2019-05/msg00235.html>. The
statfs64 structure used by alpha matches what the new kernel syscalls
use.
Tested with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/alpha/kernel-features.h
(__ASSUME_STATFS64): Only undefine if [__LINUX_KERNEL_VERSION <
0x050100].
* sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_STATX):

The tgkill function is sometimes used in crash handlers.
<bits/signal_ext.h> follows the same approach as <bits/unistd_ext.h>
(which was added for the gettid system call wrapper).

The twalk function is very difficult to use in a multi-threaded
program because there is no way to pass external state to the

Fixes build using v5.1-rc1 headers.
The kernel has cleaned up how these are defined. Previous behavior
was to define __NR_osf_shmat as 209 and not define __NR_shmat.

__NR_osf_shmat as __NR_shmat.

On platforms where long double may have the same format as double
(-mlong-double-64), error and error_at_line do not take that into
account and might produce wrong output if a long double conversion is
requested by the format string ('%Lf'). This patch adds compatibility
functions for this situation and redirects calls via header magic.
Tested for powerpc, powerpc64 and powerpc64le.

When support for long double format with 128-bits (-mlong-double-128)
was added for platforms where long double had the same format as double,
such as powerpc, compatibility versions for the functions listed in the
commit title were missed. Since the older format of long double can
still be used (with -mlong-double-64), using these functions with a
format string that requests the printing of long double variables will
produce wrong outputs.
This patch adds the missing compatibility functions and header magic to
redirect calls to them when -mlong-double-64 is in use.
Tested for powerpc, powerpc64 and powerpc64le.

The functions argp_error and argp_failure are missing support for

when -mlong-double-64 is in use.

Alpha rt_sigaction syscall uses a slight different kernel ABI than
generic one:
arch/alpha/kernel/signal.c
90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act,
91 struct sigaction __user *, oact,
92 size_t, sigsetsize, void __user *, restorer)
Similar as sparc, the syscall expects a restorer function. However
different than sparc, alpha defines the restorer as the 5th argument
(sparc defines as the 4th).
This patch removes the arch-specific alpha sigaction implementation,
adapt the Linux generic one to different restore placements (through
STUB macro), and make alpha use the Linux generic kernel_sigaction
definition.
Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity).
* sysdeps/unix/sysv/linux/alpha/Makefile: Update comment about
__syscall_rt_sigaction.

kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment
"However, SH is lame, and still does not have a 64-bit inode field.".
The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha
case is, however, trivially useless: none of the files that test
__ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel
support for stat64 syscalls, with a 64-bit st_ino field, in Linux
2.6.4; the define to 0 for Alpha in glibc predates that).
The SH kernel gained support for a 64-bit st_ino in struct stat64 in
commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64()
syscall."), which is in Linux 2.6.22 and later. So the redefinition
of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of
the files testing it do so immediately after a stat64-family syscall
has been used, which will always have set the 64-bit st_ino correctly
(in addition to the 32-bit __st_ino), while the relevant code
__xstat32_conv executes only after such a syscall in the function
calling __xstat32_conv.
Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it.
Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv
renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases
around it identical, so that conditional is also removed.
Tested compilation with build-many-glibcs.py for its Alpha and SH
configurations; also ran the glibc testsuite for x86_64 and x86.

Introduce new pow symbol version that doesn't do SVID compatible error
handling. The standard errno and fp exception based error handling is
inline in the new code and does not have significant overhead.
The wrapper is disabled for sysdeps/ieee754/dbl-64 by using empty
w_pow.c and enabled for targets with their own pow implementation or
ifunc dispatch on __ieee754_pow by including math/w_pow.c.
The compatibility symbol version still uses the wrapper with SVID error
handling around the new code. There is no new symbol version nor
compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv).
On targets where previously powl was an alias of pow, now it points to
the compatibility symbol with the wrapper, because it still need the
SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g. arm)
and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well.
The __pow_finite symbol is now an alias of pow. Both __pow_finite and
pow set errno and thus not const functions.
The ia64 asm is changed so the compat and new symbol versions map to the
same address.
On x86_64 #include <math.h> was added before macro definitions that
may affect that header.
Tested with build-many-glibcs.py.

by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and
math/w_exp2.c files use the wrapper template and can be included by
targets that have their own exp and exp2 implementations or use ifunc
on the glibc internal __ieee754_exp symbol.
The compatibility symbol versions still use the wrapper with SVID error
handling around the new code. There is no new symbol version nor
compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv).
On targets where previously expl and exp2l were aliases of exp and exp2,
now they point to the compatibility symbols with the wrapper, because
they still need the SVID compatible error handling. This affects
NO_LONG_DOUBLE (e.g arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets
as well.
The _finite symbols are now aliases of the standard symbols (they have
no performance advantage anymore). Both the standard symbols and
_finite symbols set errno and thus not const functions.
The ia64 asm is changed so the compat and new symbol versions map to the
same address.
On x86_64 #include <math.h> was added before macro definitions that may
affect that header (the new macro name is __exp instead of __ieee754_exp
which breaks some math.h macros).
