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.

Continuing the preparation for additional _FloatN / _FloatNx type
support, this patch adds support to type-generic strtod tests.
GEN_STRTOD_TEST_FOREACH and STRTOD_TEST_FOREACH are made to handle the
full set of such types. tst-strtod-round-skeleton.c is updated for
those types it can handle without needing changes to the generator
(i.e. those types that have already-handled formats).
Tested for x86_64.
* stdlib/tst-strtod.h (F16): New macro.
(F32): Likewise.
(F64): Likewise.
(F32X): Likewise.
(F64X): Likewise.
(F128X): Likewise.
(IF_FLOAT16): Likewise.
(IF_FLOAT32): Likewise.
(IF_FLOAT64): Likewise.
(IF_FLOAT32X): Likewise.
(IF_FLOAT64X): Likewise.
(IF_FLOAT128X): Likewise.
(GEN_TEST_STRTOD_FOREACH): Conditionally call macros for _Float16,
_Float32, _Float64, _Float32x, _Float64x and _Float128x.
(STRTOD_TEST_FOREACH): Likewise.
* stdlib/tst-strtod-round-skeleton.c (CHOOSE_f32): New macro.
(CHOOSE_f64): Likewise.
(CHOOSE_f32x): Likewise.
(CHOOSE_f64x): Likewise.
The macro F128 in stdlib/tst-strtod.h is defined to provide the literal
suffix for _Float128 constants. It uses the macro __f128 (), which is
defined in bits/floatn.h to provide the correct literal suffix depending on
what is provided by the compiler.
However, F128 was not being expanded and only worked correctly, when
compiling with GCC 7 (or greater), since F128 is the literal suffix itself.
This patch adds an additional macro expansion so that the macro F128
expands to the correct literal suffix on older compilers.
* stdlib/tst-strtod.h (MMFUNC): New macro to provide an addition
macro expansion.
(GEN_TEST_STRTOD_FOREACH): Use MMFUNC for _Float128.
The implementations are contained with sysdeps/ieee754/float128 as
they are only built when _Float128 is enabled within libc/m.
* include/gmp.h (__mpn_construct_float128): New declaration.
* include/stdlib.h: Include bits/floatn.h for _Float128 tests.
(__strtof128_l): New declaration.
(__strtof128_nan): Likewise.
(__wcstof128_nan): Likewise.
(__strtof128_internal): Likewise.
(____strtof128_l_internal): Likewise.
* include/wchar.h: Include bits/floatn.h for _Float128 tests.
(__wcstof128_l): New declaration.
(__wcstof128_internal): Likewise.
* stdlib/Makefile (bug-strtod2): Link libm too.
* stdlib/stdlib.h (strtof128): New declaration.
(strtof128_l): Likewise.
* stdlib/tst-strtod-nan-locale-main.c: Updated to use
tst-strtod.h macros to ensure float128 gets tested too.
* stdlib/tst-strtod-round-skeleton.c (CHOOSE_f128): New macro.
* stdlib/tst-strtod.h: Include bits/floatn.h for _Float128
tests.
(IF_FLOAT128): New macro.
(GEN_TEST_STRTOD): Update to optionally include _Float128 in
the tests.
(STRTOD_TEST_FOREACH): Likewise.
* sysdeps/ieee754/float128/Makefile: Insert new strtof128 and
wcstof128 functions into libc.
* sysdeps/ieee754/float128/Versions: Add exports for the above
new functions.
* sysdeps/ieee754/float128/mpn2float128.c: New file.
* sysdeps/ieee754/float128/strtod_nan_float128.h: New file.
* sysdeps/ieee754/float128/strtof128.c: New file.
