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

/* 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. */
