*	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
*	linux: Add helper function to optimize 64-bit time_t fallback support	Adhemerval Zanella	2020-08-24	1	-0/+70
	These helper functions are used to optimize the 64-bit time_t support on configurations that requires support for 32-bit time_t fallback (!__ASSUME_TIME64_SYSCALLS). The idea is once the kernel advertises that it does not have 64-bit time_t support, glibc will stop to try issue the 64-bit time_t syscall altogether. For instance: #ifndef __NR_symbol_time64 # define __NR_symbol_time64 __NR_symbol #endif int r; if (supports_time64 ()) { r = INLINE_SYSCALL_CALL (symbol, ...); if (r == 0 \|\| errno != ENOSYS) return r; mark_time64_unsupported (); } #ifndef __ASSUME_TIME64_SYSCALLS <32-bit fallback syscall> #endif return r; On configuration with default 64-bit time_t this optimization should be optimized away by the compiler resulting in no overhead.
