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

/* The semantics of zero/non-zero values of undefined symbols differs
|
|
depending on whether the non-PIC ABI is in use. Under the non-PIC
|
|
ABI, a non-zero value indicates that there is an address reference
|
|
to the symbol and thus it must always be resolved (except when
|
|
resolving a jump slot relocation) to the PLT entry whose address is
|
|
provided as the symbol's value; a zero value indicates that this
|
|
canonical-address behaviour is not required. Yet under the classic
|
|
MIPS psABI, a zero value indicates that there is an address
|
|
reference to the function and the dynamic linker must resolve the
|
|
symbol immediately upon loading. To avoid conflict, symbols for
|
|
which the dynamic linker must assume the non-PIC ABI semantics are
|
|
marked with the STO_MIPS_PLT flag. */
