- Update to glibc 2.35
Major new features:
* Unicode 14.0.0 Support
* Bump r_version in the debugger interface to 2
* Support for the C.UTF-8 locale has been added to glibc
* <math.h> functions that round their results to a narrower type, and
corresponding <tgmath.h> macros, are added from TS 18661-1:2014, TS
18661-3:2015 and draft ISO C2X
* <math.h> functions for floating-point maximum and minimum,
corresponding to new operations in IEEE 754-2019, and corresponding
<tgmath.h> macros, are added from draft ISO C2X
* <math.h> macros for single-precision float constants are added as a
GNU extension
* The __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__ macros are
predefined as specified in TS 18661-1:2014
* The exp10 functions in <math.h> now have a corresponding type-generic
macro in <tgmath.h>
* The ISO C2X macro _PRINTF_NAN_LEN_MAX has been added to <stdio.h>
* printf-family functions now support the %b format for output of
integers in binary, as specified in draft ISO C2X, and the %B variant
of that format recommended by draft ISO C2X
* A new DSO sorting algorithm has been added in the dynamic linker that uses
topological sorting by depth-first search (DFS), solving performance issues
of the existing sorting algorithm when encountering particular circular
object dependency cases
* A new tunable, glibc.rtld.dynamic_sort, can be used to select between
the two DSO sorting algorithms
* ABI support for a new function '__memcmpeq'. '__memcmpeq' is meant
to be used by compilers for optimizing usage of 'memcmp' when its
return value is only used for its boolean status (forwarded request 951353 from Andreas_Schwab)

- Add ExtraBuildFlags for build flags that cannot be passed to configure.
------------------( below changes from previous sr )---------------------------
- Pass livepatchable flags directly to make.
- Add optional support for livepatches (JSC #SLE-20049).
- Generate ipa-clones tarball artifact when livepatch support is enabled.
Userspace Livepatching allows your application to be updated without restarting. For a library to be livepatchable, it has to be compiled with special flags (-fpatchable-functions-entry=X,Y).
To aid the development of livepatches, ipa-clones are also generated in the build process and packed into a livepatch-devel package. This package is meant to be used by developers during their workflow: these files contains log of changes that gcc did in the compiled code that may change code layout, which must be accounted when developing a livepatch. For instance, livepatching a function which is inlined requires livepatching every function that calls it. Tools that use such files already exists in kernel-livepatching and we aim porting them to userspace livepatching as well.

- Update to glibc 2.34
Major new features:
* When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
PTHREAD_STACK_MIN is no longer constant and is redefined to
sysconf(_SC_THREAD_STACK_MIN)
* Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ
* The dynamic linker implements the --list-diagnostics option, printing
a dump of information related to IFUNC resolver operation and
glibc-hwcaps subdirectory selection
* On Linux, the function execveat has been added
* The ISO C2X function timespec_getres has been added
* The feature test macro __STDC_WANT_IEC_60559_EXT__, from draft ISO
C2X, is supported to enable declarations of functions defined in Annex F
of C2X
* Add support for 64-bit time_t on configurations like x86 where time_t
is traditionally 32-bit
* The main gconv-modules file in glibc now contains only a small set of
essential converter modules and the rest have been moved into a supplementary
configuration file gconv-modules-extra.conf in the gconv-modules.d directory
in the same GCONV_PATH
* On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used
to configure the size of the thread stack cache
* The function _Fork has been added as an async-signal-safe fork replacement
since Austin Group issue 62 droped the async-signal-safe requirement for
fork (and it will be included in the future POSIX standard)
* On Linux, the close_range function has been added
* The function closefrom has been added
* The posix_spawn_file_actions_closefrom_np function has been added, enabling
posix_spawn and posix_spawnp to close all file descriptors great than or

- Update to glibc 2.33
* The dynamic linker accepts the --list-tunables argument which prints
all the supported tunables.
* The dynamic linker accepts the --argv0 argument and provides opportunity
to change argv[0] string.
* The dynamic linker loads optimized implementations of shared objects
from subdirectories under the glibc-hwcaps directory on the library
search path if the system's capabilities meet the requirements for
that subdirectory.
* The new --help option of the dynamic linker provides usage and
information and library search path diagnostics.
* The mallinfo2 function is added to report statistics as per mallinfo,
but with larger field widths to accurately report values that are
larger than fit in an integer.
* Add <sys/platform/x86.h> to provide query macros for x86 CPU features.
* A new fortification level _FORTIFY_SOURCE=3 is available.
* The mallinfo function is marked deprecated.
* When dlopen is used in statically linked programs, alternative library
implementations from HWCAP subdirectories are no longer loaded.
* The deprecated <sys/vtimes.h> header and the function vtimes have been
removed.
* On s390(x), the type float_t is now derived from the macro
__FLT_EVAL_METHOD__ that is defined by the compiler, instead of being
hardcoded to double.
* A future version of glibc will stop loading shared objects from the
"tls" subdirectories on the library search path, the subdirectory that
corresponds to the AT_PLATFORM system name, and also stop employing
the legacy AT_HWCAP search mechanism.
* CVE-2021-3326: An assertion failure during conversion from the
ISO-20220-JP-3 character set using the iconv function has been fixed. (forwarded request 868599 from Andreas_Schwab)
