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

/* The macro PAGE_COPY_FWD_MAYBE defined in memcopy.h is used in memmove if the
|
|
PAGE_COPY_THRESHOLD macro is set to a non-zero value. The default is 0,
|
|
that is copying by pages is not implemented.
|
|
|
|
System-specific pagecopy.h files that want to support page copying should
|
|
define these macros:
|
|
|
|
PAGE_COPY_THRESHOLD
|
|
-- A non-zero minimum size for which virtual copying by pages is worthwhile.
|
|
|
|
PAGE_SIZE
|
|
-- Size of a page.
|
|
|
|
PAGE_COPY_FWD (dstp, srcp, nbytes_left, nbytes)
|
|
-- Macro to perform the virtual copy operation.
|
|
The pointers will be aligned to PAGE_SIZE bytes.
