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 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master

1. Add the directories to hold POWER10 files.
2. Add support to select POWER10 libraries based on AT_PLATFORM.
3. Let submachine=power10 be set automatically.

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

-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 \

The power7 logb implementation does not show a performance gain on
ISA 2.07+ chips with faster floating-point to GRP instructions
(currently POWER8 and POWER9).
This patch moves the POWER7 implementation to generic one and enables
it for POWER7. It also add some cleanup to use inline floating-point
number instead of define them using static const.
The performance difference is for POWER9:
- Without patch:
"logb": {
"subnormal": {
"duration": 4.99202e+09,
"iterations": 8.83662e+08,
"max": 75.194,
"min": 5.501,
"mean": 5.64925
},
"normal": {
"duration": 4.97063e+09,
"iterations": 9.97094e+08,
"max": 46.489,
"min": 4.956,
"mean": 4.98512
}
}
- With patch:
"logb": {
"subnormal": {
"duration": 4.97226e+09,
"iterations": 9.92036e+08,
"max": 77.209,
"min": 4.892,
"mean": 5.01218
},
"normal": {
"duration": 4.96192e+09,
"iterations": 1.07545e+09,
"max": 12.361,
"min": 4.593,
"mean": 4.61382
}
}
The ifunc implementation is also enabled only for powerpc64.

This patches consolidates all the powerpc trunc{f} implementations on

uses either the compiler builts for ISA 2.03+ (which generates the
frim instruction) or a generic implementation which uses FP only
operations.

require the fallback generic implementation).

Currently, powerpc, powerpc64, and powerpc64le imply the same set of
subdirectories from sysdeps/ieee754: flt-32, dbl-64, ldbl-128ibm, and
ldbl-opt. In preparation for the transition of the long double format -
from IBM Extended Precision to IEEE 754 128-bits floating-point - on
powerpc64le, this patch splits the shared Implies file into three
separate files (one for each of the powerpc architectures), without
changing their contents. Future patches will modify powerpc64le.
* sysdeps/powerpc/Implies: Removed. Previous contents copied to...
* sysdeps/powerpc/powerpc32/Implies-after: ... here.

The creation of the divergent sysdeps directory for powerpc64le
commit 2f7f3cd8cd302bb10908c86f3f7b349df0a78e6a
Author: Paul E. Murphy <murphyp@linux.vnet.ibm.com>
Date: Fri Jul 15 18:04:40 2016 -0500
powerpc64le: Create divergent sysdep directory for powerpc64le.
allowed float128 to be enabled for powerpc64le (little-endian) and not
for powerpc64 (big-endian). Since the only intended difference between
them was the presence or absence of the float128 interface, the sysdeps
directory for powerpc64le explicitly reused the files from powerpc64
(through the use of Implies files).
Although this works, it also means that files under the powerpc64
directory might be preferred over files under powerpc64le. For
instance, on a build for powerpc64le with target set to power9, a file
from powerpc64/power5 might get built, even though a file with the same
name exists in powerpc64le/power8. That happens because the processor
hierarchy was only defined in the sysdeps directory for powerpc64 (and
borrowed by powerpc64le).
This patch fixes this behavior, by creating new subdirectories under
powerpc64 (i.e.: powerpc64/be and powerpc64/le) and creating new Implies
files to provide the hierarchy of processors for powerpc64 and
powerpc64le separately. These changes have no effect on installed,
stripped binaries (which remain unchanged).
Tested that installed stripped binaries are unchanged and that there are
no regressions on powerpc64 and powerpc64le.
