*	Update copyright dates with scripts/update-copyrights	Paul Eggert	2021-01-02	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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
*	alpha: Fix static gettimeofday symbol	Adhemerval Zanella	2020-02-13	1	-5/+2
\| \| \| \| \| \| \| \|	By undef strong_alias on alpha implementation, the default_symbol_version macro becomes an empty macro on static build. It fixes the issue introduced at c953219420. Checked on alpha-linux-gnu with a 'make check run-built-tests=no'.
*	alpha: Use generic gettimeofday implementation	Adhemerval Zanella	2020-02-12	1	-1/+8
\| \| \| \| \| \| \| \| \|	It makes alpha no longer reports information about a system-wide time zone and moves the version logic on the alpha implementation. Checked on a build and check-abi for alpha-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de>

*	Use clock_gettime to implement gettimeofday.	Adhemerval Zanella	2019-10-30	1	-0/+22
	Consolidate generic gettimeofday implementation to use clock_gettime. Linux ports that still provide gettimeofday through vDSO are not changed. Remove sysdeps/unix/clock_gettime.c, which implemented clock_gettime using gettimeofday; new OS ports must provide a real implementation of clock_gettime. Rename sysdeps/mach/gettimeofday.c to sysdeps/mach/clock_gettime.c and convert into an implementation of clock_gettime. It only supports CLOCK_REALTIME; Mach does not appear to have any support for monotonic clocks. It uses __host_get_time, which provides at best microsecond resolution. Hurd is currently using sysdeps/posix/clock_getres.c for clock_getres; its output for CLOCK_REALTIME is based on sysconf (_SC_CLK_TCK), and I do not know whether that gives the correct result. Unlike settimeofday, there are no known uses of gettimeofday's vestigial "get time zone" feature that are not bugs. (The per-process timezone support in localtime and friends is unrelated, and the programs that set the kernel's offset between the hardware clock and UTC do not need to read it back.) Therefore, this feature is dummied out. Henceforth, if gettimeofday's "struct timezone" argument is not NULL, it will write zeroes to both fields. Any program that is actually looking at this data will thus think it is running in UTC, which is probably more correct than whatever it was doing before. [__]gettimeofday no longer has any internal callers, so we can now remove its internal prototype and PLT bypass aliases. The __gettimeofday@GLIBC_2.0 export remains, in case it is used by any third-party code. It also allows to simplify the arch-specific implementation on x86 and powerpc to remove the hack to disable the internal route to non iFUNC variant for internal symbol. This patch also fixes a missing optimization on aarch64, powerpc, and x86 where the code used on static build do not use the vDSO. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.
