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

/* GCC uses unordered comparison instructions like cebr (Short BFP COMPARE)
|
|
when it should use ordered comparison instructions like kebr
|
|
(Short BFP COMPARE AND SIGNAL) in order to raise invalid exceptions if
|
|
any operand is quiet (or signaling) NAN. See gcc bugzilla:
|
|
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77918>.

There exists an equivalent gcc bugzilla for Intel:

<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52451>.
|
|
This s390 gcc bug is fixed with gcc 10, thus we don't need the workaround

to call feraiseexcept (FE_INVALID) in math/s_iseqsig_template.c. */
