I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.
remote: *** 912-#endif
remote: *** 913:
remote: *** 914-
remote: *** error: lines with trailing whitespace found
...
remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '
s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
$(find $(git ls-files) -prune -type f \
! -name '*.po' \
! -name 'ChangeLog*' \
! -path COPYING ! -path COPYING.LIB \
! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \

! '(' -name configure \
-execdir test -f configure.ac -o -f configure.in ';' ')' \
! '(' -name preconfigure \
-execdir test -f preconfigure.ac ';' ')' \
-print)
and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure
# Omit irrelevant whitespace and comment-only changes,
# perhaps from a slightly-different Autoconf version.
git checkout -f \
sysdeps/csky/configure \

Similar to the x86_64 build issues, glibc fails to build for armv7
with current mainline GCC because of aliases declared in the course of
defining IFUNCs, which copy their attributes from a header
declaration, ending up with fewer attributes than the (built-in)
string function they alias: the relevant attributes (nonnull, leaf)
are present on the header declaration, but elided therefrom when glibc
itself if being built (whatever the reasons are for disabling the
nonnull and leaf attributes in that case, and whether or not those
reasons are actually still valid). This patch fixes the issue
similarly to the x86_64 fix, by adding an addition __attribute_copy__
use (in this case, on the definition of arm_libc_ifunc_hidden_def).
Tested with build-many-glibcs.py build for armeb-linux-gnueabi-be8.
* sysdeps/arm/arm-ifunc.h [SHARED] (arm_libc_ifunc_hidden_def):
Use __attribute_copy__ to copy attributes from name.

This patch refactor ARM memcpy ifunc selector to a C implementation.
No functional change is expected, including ifunc resolution rules.
It also adds some cleanup:
- Internal memcpy hidden definition (__GI_memcpy) is now a hidden
symbol.
- No need to create hidden definition for the ifunc variants.
Checked on armv7-linux-gnueabihf and with a build for arm-linux-gnueabi,
arm-linux-gnueabihf with and without multiarch support and with both
GCC 7.1 and GCC mainline. I also checked with the some possible
multiarch different configurations that trigger different memcpy
buids (__ARM_NEON__ && !__SOFT_FP__, !__ARM_NEON__ && !__SOFT_FP__, and
!__ARM_NEON__ && __SOFT_FP__).
* sysdeps/arm/arm-ifunc.h: New file.

* sysdeps/arm/armv7/multiarch/memcpy_neon.S [!__ARM_NEON__]

* sysdeps/arm/armv7/multiarch/memcpy_vfp.S [!__ARM_NEON_]

* sysdeps/arm/armv7/multiarch/Makefile [$(subdir) = string]

* sysdeps/arm/armv7/multiarch/memcpy.S: Remove file.
