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.

This patch adds an ifunc variant to use the cu instruction on arch12 CPUs.
This new ifunc variant can be built if binutils support z13 vector
instructions. At runtime, HWCAP_S390_VXE decides if we can use the
cu24 instruction.
ChangeLog:
* sysdeps/s390/utf16-utf32-z9.c (__from_utf16_loop_vx_cu):
Use vector and cu24 instruction.
* sysdeps/s390/multiarch/utf16-utf32-z9.c:
Add __from_utf16_loop_vx_cu in ifunc resolver.
This patch adds an ifunc variant to use the cu instruction on arch12 CPUs.
This new ifunc variant can be built if binutils support z13 vector
instructions. At runtime, HWCAP_S390_VXE decides if we can use the
cu42 instruction.
ChangeLog:
* sysdeps/s390/utf16-utf32-z9.c (__to_utf16_loop_vx_cu):
Use vector and cu42 instruction.
* sysdeps/s390/multiarch/utf16-utf32-z9.c:
Add __to_utf16_loop_vx_cu in ifunc resolver.
The utf16-utf32-z9.c iconv module is using ifunc and thus the ifunc part should
be in multiarch folder. Otherwise ifunc is used even if you configure
with --disable-multi-arch.
This patch moves the ifunc resolvers to the new file
sysdeps/s390/multiarch/utf16-utf32-z9.c. The resolvers are now implemented
with s390_libc_ifunc_expr macro instead of using gcc attribute ifunc directly.
The ifunc versions are implemented in sysdeps/s390/utf16-utf32-z9.c.
Each version is only implemented if needed or supported. Therefore there is
a block at beginning of the file which selects the versions which should be
defined depending on support for multiarch, vector-support and used minimum
architecture level. This block defines HAVE_[FROM|TO]_[C|VX] to 1 or 0.
The code below is rearranged and surrounded
by #if HAVE_[FROM|TO]_[C|VX] == 1. There is no functional change.
ChangeLog:
* sysdeps/s390/multiarch/utf16-utf32-z9.c: New File.
* sysdeps/s390/utf16-utf32-z9.c: Move ifunc resolvers to multiarch
folder and define ifunc versions depending on HAVE_[FROM|TO]_[C|VX].
(HAVE_FROM_C, HAVE_FROM_VX, HAVE_TO_C, HAVE_TO_VX, FROM_LOOP_DEFAULT,
FROM_LOOP_C, FROM_LOOP_VX, TO_LOOP_DEFAULT, TO_LOOP_C, TO_LOOP_VX):
New Define.
