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
DELOUSE was added to asm code to make them compatible with non-LP64
ABIs, but it is an unfortunate name and the code was not compatible
with ABIs where pointer and size_t are different. Glibc currently
only supports the LP64 ABI so these macros are not really needed or
tested, but for now the name is changed to be more meaningful instead
of removing them completely.
Some DELOUSE macros were dropped: clone, strlen and strnlen used it
unnecessarily.
The out of tree ILP32 patches are currently not maintained and will
likely need a rework to rebase them on top of the time64 changes.
* sysdeps/aarch64/multiarch/memset_base64.S (DC_ZVA_THRESHOLD):
Disable DC ZVA code if this macro is defined as zero.
* sysdeps/aarch64/multiarch/memset_emag.S (DC_ZVA_THRESHOLD):
Change to zero to disable using DC ZVA.
This version uses general register based memory store instead of
vector register based, for the former is faster than the latter
in emag.
The fact that DC ZVA size in emag is 64-byte, is used by IFUNC
dispatch to select this memset, so that cost of runtime-check on
DC ZVA size can be saved.
* sysdeps/aarch64/multiarch/Makefile (sysdep_routines):
Add memset_emag.
* sysdeps/aarch64/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Add __memset_emag to memset ifunc.
* sysdeps/aarch64/multiarch/memset.c (libc_ifunc):
Add IS_EMAG check for ifunc dispatch.
* sysdeps/aarch64/multiarch/memset_base64.S: New file.
* sysdeps/aarch64/multiarch/memset_emag.S: New file.
