Starting from glibc 2.1, crt1.o contains _IO_stdin_used which is checked
by _IO_check_libio to provide binary compatibility for glibc 2.0. Add
crt1-2.0.o for tests against glibc 2.0. Define tests-2.0 for glibc 2.0
compatibility tests. Add and update glibc 2.0 compatibility tests for
stderr, matherr and pthread_kill.

This patch is based on __strcmp_power10.
Improvements from __strncmp_power9:
1. Uses new POWER10 instructions
- This code uses lxvp to decrease contention on load
by loading 32 bytes per instruction.
2. Performance implication
- This version has around 38% better performance on average.
- Minor performance regression is seen for few small sizes
and specific combination of alignments.

This adds the OpenRISC hard float glibc variant to the build many
script. We update the compiler for glibc to support hard-float
multilibs to allow us to use a single generic compiler for all glibc
variants, this requires updating the compiler name.
Tested and all builds are passing.

This patch adds hardware floating point support to OpenRISC. Hardware
floating point toolchain builds are enabled by passing the machine
specific argument -mhard-float to gcc via CFLAGS. With this enabled GCC
generates floating point instructions for single-precision operations
and exports __or1k_hard_float__.
There are 2 main parts to this patch.
- Implement fenv functions to update the FPCSR flags keeping it in sync
with sfp (software floating point).
- Update machine context functions to store and restore the FPCSR
state.
*On mcontext_t ABI*
This patch adds __fpcsr to mcontext_t. This is an ABI change, but also
an ABI fix. The Linux kernel has always defined padding in mcontext_t
that space was missing from the glibc ABI. In Linux this unused space
has now been re-purposed for storing the FPCSR. This patch brings
OpenRISC glibc in line with the Linux kernel and other libc
implementation (musl).
Compatibility getcontext, setcontext, etc symbols have been added to
allow for binaries expecting the old ABI to continue to work.
*Hard float ABI*
The calling conventions and types do not change with OpenRISC hard-float
so glibc hard-float builds continue to use dynamic linker
/lib/ld-linux-or1k.so.1.
*Testing*
I have tested this patch both with hard-float and soft-float builds and
the test results look fine to me. Results are as follows:

Commit c73c96a4a1af1326df7f96eec58209e1e04066d8 updated memcpy.S and
mempcpy.S, but omitted memmove.S and memset.S. As a result, the static
library built as PIC, whether with or without multiarch support,
contains two definitions for each of the __memmove_chk and __memset_chk
symbols.

After this change, regardless of PIC options, the static library, built
for i686 with multiarch contains implementations of these functions

without multiarch contains implementations of these functions
respectively from sysdeps/i386/memmove_chk.S and
sysdeps/i386/memset_chk.S. This ensures that memmove and memset won't

When timespect_get.c was impelemented the license did not include

While AT_NO_AUTOMOUNT is similar in function to the Hurd's O_NOTRANS,
there are significant enough differences in semantics:
1. AT_NO_AUTOMOUNT has no effect on already established mounts,
whereas O_NOTRANS causes the lookup to ignore both passive and active
translators. A better approximation of the AT_NO_AUTOMOUNT behavior
would be to honor active translators, but avoid starting passive
ones; like what the file_name_lookup_carefully () routine from
sutils/clookup.c in the Hurd source tree does.
2. On GNU/Hurd, translators are used much more pervasively than mounts
on "traditional" Unix systems: among other things, translators
underlie features like symlinks, device nodes, and sockets. And while
on a "traditional" Unix system, the mountpoint and the root of the
mounted tree may look similar enough for many purposes (they're both
directories, for one thing), the Hurd allows for any combination of
the two node types, and indeed it is common to have e.g. a device
node "mounted" on top of a regular file node on the underlying
filesystem. Ignoring the translator and stat'ing the underlying node
is therefore likely to return very different results from what you'd
get if you stat the translator's root node.
In practice, mapping AT_NO_AUTOMOUNT to O_NOTRANS was breaking GNU
Coreutils, including stat(1) and ls(1):
$ stat /dev/hd0s1
File: /dev/hd0s1
Size: 0 Blocks: 8 IO Block: 8192 regular empty file
Device: 0,8 Inode: 32866 Links: 1
This was also breaking GNOME's glib, where a g_local_file_stat () call
that is supposed to stat () a file through a symlink uses
AT_NO_AUTOMOUNT, which gets mapped to O_NOTRANS, which then causes the
stat () call to stat symlink itself like lstat () would, rather then the
file it points to, which is what the logic expects to happen.
This reverts most of 13710e7e6af6c8965cc9a63a0660cb4ce1966557
"hurd: Add support for AT_NO_AUTOMOUNT".

This reverts commit 84e93afc7 ("Switch to UTF-8 for INSTALL") and
reinstates commit c14f2e4aa ("Make sure INSTALL is ASCII plaintext")
and regenerates INSTALL.
It turns out that different versions of makeinfo (texinfo/texi2any),
at least versions 7.0.3 and 7.1, put unicode quote glyphs in different
places (specifically whether contractions like you'd, don't, aren't or
you'll use ’ or '). This breaks the make dist target as used for
(snapshot) releases, which have a check on the regenerated INSTALL
file. Using --disable-encoding generates the same plaintext ASCII on
all versions.
An alternative would be to regenerate INSTALL with texinfo 7.1 and
require at least that version. But that seems too soon while various
distros don't have 7.1 yet. We can try again to use UTF-8 for INSTALL
in a couple of years.

addgetnetgrentX (bug 31680)
This avoids potential memory corruption when the underlying NSS
callback function does not use the buffer space to store all strings
(e.g., for constant strings).
Instead of custom buffer management, two scratch buffers are used.
This increases stack usage somewhat.

(bug 31678)
The addgetnetgrentX call in addinnetgrX may have failed to produce

Use db->negtimeout as the fallback value if there is no result data;
the timeout is also overwritten below.
Also avoid sending a second not-found response. (The client
disconnects after receiving the first response, so the data stream did
not go out of sync even without this fix.) It is still beneficial to
add the negative response to the mapping, so that the client can get
it from there in the future, instead of going through the socket.

Delay setting file->decided until the data has been successfully loaded
by _nl_load_locale(). If the function fails to load the data then we
must return and error and leave decided untouched to allow the caller to
attempt to load the data again at a later time. We should not set
decided to 1 early in the function since doing so may prevent attempting
to load it again. We want to try loading it again because that allows an
open to fail and set errno correctly.
On the other side of this problem is that if we are called again with
the same inputs we will fetch the cached version of the object and carry
out no open syscalls and that fails to set errno so we must set errno to
ENOENT in that case. There is a second code path that has to be handled
where the name of the locale matches but the codeset doesn't match.
These changes ensure that errno is correctly set on failure in all the
return paths in _nl_find_locale().
Adds tst-locale-loadlocale to cover the bug.

by glibc). The license is also changed from GPL 3.0 to 2.1, with
permission from the authors (Bruno Haible and Paul Eggert).
The sync also removed the clock fallback, since clock_gettime
with CLOCK_REALTIME is expected to always succeed.
It syncs with gnulib commit 323834962817af7b115187e8c9a833437f8d20ec.
Checked on x86_64-linux-gnu.

None of the existing tests seem to cover the case where
_dl_signal_error is called without an active error handler.
The new elf/tst-rtld-does-not-exist test triggers such a
_dl_signal_error call from _dl_map_object.

_dl_signal_error may be called with objname == NULL. _dl_exception_create
checks objname == NULL. But fatal_error doesn't. Check objname before
calling fatal_error. This fixes BZ #31596.
