* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-021-1/+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

* Add single-thread.h headerAdhemerval Zanella2019-05-141-39/+42
| | | | | | | | | | | | | | | | | | | | | | | | | This patch move the single-thread syscall optimization defintions from syscall-cancel.h to new header file single-thread.h and also move the cancellation definitions from pthreadP.h to syscall-cancel.h. The idea is just simplify the inclusion of both syscall-cancel.h and single-thread.h (without the requirement of including all pthreadP.h defintions). No semantic changes expected, checked on a build for all major ABIs. * nptl/pthreadP.h (CANCEL_ASYNC, CANCEL_RESET, LIBC_CANCEL_ASYNC, LIBC_CANCEL_RESET, __libc_enable_asynccancel, __libc_disable_asynccancel, __librt_enable_asynccancel, __libc_disable_asynccancel, __librt_enable_asynccancel, __librt_disable_asynccancel): Move to ... * sysdeps/unix/sysv/linux/sysdep-cancel.h: ... here. (SINGLE_THREAD_P, RTLD_SINGLE_THREAD_P): Move to ... * sysdeps/unix/sysv/linux/single-thread.h: ... here. * sysdeps/generic/single-thread.h: New file. * sysdeps/unix/sysdep.h: Include single-thread.h. * sysdeps/unix/sysv/linux/futex-internal.h: Include sysdep-cancel.h. * sysdeps/unix/sysv/linux/lowlevellock-futex.h: Likewise.

* Linux: Consolidate {RTLD_}SINGLE_THREAD_P definitionAdhemerval Zanella2017-10-111-0/+64
Current GLIBC has two ways to implement the single thread optimization on syscalls to avoid calling the cancellation path: either by using global variables (__{libc,pthread}_multiple_thread) or by accessing the TCB field (defined by TLS_MULTIPLE_THREADS_IN_TCB). Both the variables and the macros to acces its value are defined in the architecture sysdep-cancel.h header. This patch consolidates its definition on only one header, sysdeps/unix/sysv/linux/sysdep-cancel.h, and adds a new define (SINGLE_THREAD_BY_GLOBAL) which the architecture defines if it prefer to use the global variables instead of the TCB field. This is an optimization, so if the architecture does not define it, the TCB method will be used as default. Checked on x86_64-linux-gnu and on a build with major touched ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf, hppa-linux-gnu, i686-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu, mips-linux-gnu, mips64-linux-gnu, powerpc-linux-gnu, powerpc64le-linux-gnu, s390-linux-gnu, s390x-linux-gnu, sh4-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, tilegx-linux-gnu). * sysdeps/unix/sysv/linux/aarch64/sysdep-cancel.h: Remove file. * sysdeps/unix/sysv/linux/alpha/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/arm/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/mips/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/nios2/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/sh/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/tile/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep-cancel.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Define. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Likewise. * sysdeps/unix/sysv/linux/alpha/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Likewise. * sysdeps/unix/sysv/linux/arm/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Likewise. * sysdeps/unix/sysv/linux/microblaze/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (SINGLE_THREAD_BY_GLOBAL): Likewise.
