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.

In C++ mode, __MATH_TG cannot be used for defining iseqsig, because
__MATH_TG relies on __builtin_types_compatible_p, which is a C-only
builtin. This is true when float128 is provided as an ABI-distinct type
from long double.
Moreover, the comparison macros from ISO C take two floating-point
arguments, which need not have the same type. Choosing what underlying
function to call requires evaluating the formats of the arguments, then
selecting which is wider. The macro __MATH_EVAL_FMT2 provides this
information, however, only the type of the macro expansion is relevant
(actually evaluating the expression would be incorrect).
This patch provides a C++ version of iseqsig, in which only the type of
__MATH_EVAL_FMT2 (__typeof or decltype) is used as a template parameter
for __iseqsig_type. This function calls the appropriate underlying
function.
Tested for powerpc64le and x86_64.
[BZ #22377]
* math/Makefile [C++] (tests): Add test for iseqsig.
* math/math.h [C++] (iseqsig): New implementation, which does
not rely on __MATH_TG/__builtin_types_compatible_p.
* math/test-math-iseqsig.cc: New file.
* sysdeps/powerpc/powerpc64le/Makefile
(CFLAGS-test-math-iseqsig.cc): New variable.
