- Update to glibc 2.32
  * Unicode 13.0.0 Support
  * New locale added: ckb_IQ
  * The GNU C Library now loads audit modules listed in the DT_AUDIT and
    DT_DEPAUDIT dynamic section entries of the main executable
  * powerpc64le supports IEEE128 long double libm/libc redirects when
    using the -mabi=ieeelongdouble to compile C code on supported GCC
    toolchains
  * To help detect buffer overflows and other out-of-bounds accesses
    several APIs have been annotated with GCC 'access' attribute
  * On Linux, functions the pthread_attr_setsigmask_np and
    pthread_attr_getsigmask_np have been added
  * The GNU C Library now provides the header file <sys/single_threaded.h>
    which declares the variable __libc_single_threaded
  * The functions sigabbrev_np and sigdescr_np have been added
  * The functions strerrorname_np and strerrordesc_np have been added
  * AArch64 now supports standard branch protection security hardening
    in glibc when it is built with a GCC that is configured with
    --enable-standard-branch-protection (or if -mbranch-protection=standard
    flag is passed when building both GCC target libraries and glibc,
    in either case a custom GCC is needed)
  * The deprecated <sys/sysctl.h> header and the sysctl function have been
    removed
  * The sstk function is no longer available to newly linked binaries
  * The legacy signal handling functions siginterrupt, sigpause, sighold,
    sigrelse, sigignore and sigset, and the sigmask macro have been
    deprecated
  * ldconfig now defaults to the new format for ld.so.cache
  * The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
    are no longer available to newly linked binaries, and their declarations

From 9f997ceca28f0634ad78a1ca95b84265f7801ff4 Mon Sep 17 00:00:00 2001
From: Joseph Myers <joseph@codesourcery.com>
Date: Wed, 12 Feb 2020 23:31:56 +0000
Subject: [PATCH] Avoid ldbl-96 stack corruption from range reduction of
pseudo-zero (bug 25487).
Bug 25487 reports stack corruption in ldbl-96 sinl on a pseudo-zero
argument (an representation where all the significand bits, including
the explicit high bit, are zero, but the exponent is not zero, which
is not a valid representation for the long double type).
Although this is not a valid long double representation, existing
practice in this area (see bug 4586, originally marked invalid but
subsequently fixed) is that we still seek to avoid invalid memory
accesses as a result, in case of programs that treat arbitrary binary
data as long double representations, although the invalid
representations of the ldbl-96 format do not need to be consistently
handled the same as any particular valid representation.
This patch makes the range reduction detect pseudo-zero and unnormal
representations that would otherwise go to __kernel_rem_pio2, and
returns a NaN for them instead of continuing with the range reduction
process. (Pseudo-zero and unnormal representations whose unbiased
exponent is less than -1 have already been safely returned from the
function before this point without going through the rest of range
reduction.) Pseudo-zero representations would previously result in
the value passed to __kernel_rem_pio2 being all-zero, which is
definitely unsafe; unnormal representations would previously result in
a value passed whose high bit is zero, which might well be unsafe
since that is not a form of input expected by __kernel_rem_pio2.
Tested for x86_64.
(cherry picked from commit 9333498794cde1d5cca518badf79533a24114b6f)

From 49348beafe9ba150c9bd48595b3f372299bddbb0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix build with GCC 10 when long double = double.
On platforms where long double has the same ABI as double, glibc
defines long double functions as aliases for the corresponding double
functions. The declarations of those functions in <math.h> are
disabled to avoid problems with aliases having incompatible types, but
GCC 10 now gives errors for incompatible types when the long double
function is known to GCC as a built-in function, not just when there
is an incompatible header declaration.
This patch fixes those errors by using appropriate
-fno-builtin-<function> options to compile the double functions. The
list of CFLAGS-* settings is an appropriately adapted version of that
in sysdeps/ieee754/ldbl-opt/Makefile used there for building nldbl-*.c
files; in particular, the options are used even if GCC does not
currently have a built-in function of a given function, so that adding
such a built-in function in future will not break the glibc build.
Thus, various of the CFLAGS-* settings are only for future-proofing
and may not currently be needed (and it's possible some could be
irrelevant for other reasons).
Tested with build-many-glibcs.py for arm-linux-gnueabi (compilers and
glibcs builds), where it fixes the build that previously failed.

Subject: [PATCH] riscv: Avoid clobbering register parameters in syscall
The riscv INTERNAL_SYSCALL macro might clobber the register
parameter if the argument itself might clobber any register (a function
call for instance).
This patch fixes it by using temporary variables for the expressions
between the register assignments (as indicated by GCC documentation,
6.47.5.2 Specifying Registers for Local Variables).
It is similar to the fix done for MIPS (bug 25523).
Checked with riscv64-linux-gnu-rv64imafdc-lp64d build.
