Currently the only field which is statically initialized to a non zero/null value is pthread_mutex_t.__data.__kind value. A new internal header (pthread-offset.h) is added to each major ABI with the reference value. Checked on x86_64-linux-gnu and with a build check for all affected ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf, hppa-linux-gnu, i686-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu, mips64-linux-gnu, mips64-n32-linux-gnu, mips-linux-gnu, powerpc64le-linux-gnu, powerpc-linux-gnu, s390-linux-gnu, s390x-linux-gnu, sh4-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, tilegx-linux-gnu, tilegx-linux-gnu-x32, tilepro-linux-gnu, x86_64-linux-gnu, and x86_64-linux-x32). * nptl/Makefile (tests-internal): Add tst-offsets. * nptl/tst-offsets.c: New file. * sysdeps/aarch64/nptl/pthread-offsets.h: Likewise. * sysdeps/alpha/nptl/pthread-offsets.h: Likewise. * sysdeps/arm/nptl/pthread-offsets.h: Likewise. * sysdeps/hppa/nptl/pthread-offsets.h: Likewise. * sysdeps/i386/nptl/pthread-offsets.h: Likewise. * sysdeps/ia64/nptl/pthread-offsets.h: Likewise. * sysdeps/m68k/nptl/pthread-offsets.h: Likewise. * sysdeps/microblaze/nptl/pthread-offsets.h: Likewise. * sysdeps/mips/nptl/pthread-offsets.h: Likewise. * sysdeps/nios2/nptl/pthread-offsets.h: Likewise. * sysdeps/powerpc/nptl/pthread-offsets.h: Likewise. * sysdeps/s390/nptl/pthread-offsets.h: Likewise. * sysdeps/sh/nptl/pthread-offsets.h: Likewise. * sysdeps/sparc/nptl/pthread-offsets.h: Likewise. * sysdeps/tile/nptl/pthread-offsets.h: Likewise. * sysdeps/x86_64/nptl/pthread-offsets.h: Likewise. --- ChangeLog | 19 ++++++++++++++ nptl/Makefile | 2 +- nptl/tst-offsets.c | 41 +++++++++++++++++++++++++++++++ sysdeps/aarch64/nptl/pthread-offsets.h | 1 + sysdeps/alpha/nptl/pthread-offsets.h | 1 + sysdeps/arm/nptl/pthread-offsets.h | 1 + sysdeps/hppa/nptl/pthread-offsets.h | 1 + sysdeps/i386/nptl/pthread-offsets.h | 1 + sysdeps/ia64/nptl/pthread-offsets.h | 1 + sysdeps/m68k/nptl/pthread-offsets.h | 1 + sysdeps/microblaze/nptl/pthread-offsets.h | 1 + sysdeps/mips/nptl/pthread-offsets.h | 5 ++++ sysdeps/nios2/nptl/pthread-offsets.h | 1 + sysdeps/powerpc/nptl/pthread-offsets.h | 7 ++++++ sysdeps/s390/nptl/pthread-offsets.h | 7 ++++++ sysdeps/sh/nptl/pthread-offsets.h | 1 + sysdeps/sparc/nptl/pthread-offsets.h | 7 ++++++ sysdeps/tile/nptl/pthread-offsets.h | 7 ++++++ sysdeps/x86_64/nptl/pthread-offsets.h | 1 + 19 files changed, 105 insertions(+), 1 deletion(-) create mode 100644 nptl/tst-offsets.c create mode 100644 sysdeps/aarch64/nptl/pthread-offsets.h create mode 100644 sysdeps/alpha/nptl/pthread-offsets.h create mode 100644 sysdeps/arm/nptl/pthread-offsets.h create mode 100644 sysdeps/hppa/nptl/pthread-offsets.h create mode 100644 sysdeps/i386/nptl/pthread-offsets.h create mode 100644 sysdeps/ia64/nptl/pthread-offsets.h create mode 100644 sysdeps/m68k/nptl/pthread-offsets.h create mode 100644 sysdeps/microblaze/nptl/pthread-offsets.h create mode 100644 sysdeps/mips/nptl/pthread-offsets.h create mode 100644 sysdeps/nios2/nptl/pthread-offsets.h create mode 100644 sysdeps/powerpc/nptl/pthread-offsets.h create mode 100644 sysdeps/s390/nptl/pthread-offsets.h create mode 100644 sysdeps/sh/nptl/pthread-offsets.h create mode 100644 sysdeps/sparc/nptl/pthread-offsets.h create mode 100644 sysdeps/tile/nptl/pthread-offsets.h create mode 100644 sysdeps/x86_64/nptl/pthread-offsets.h -- 2.7.4 diff --git a/nptl/Makefile b/nptl/Makefile index d819349..7492b06 100644 --- a/nptl/Makefile +++ b/nptl/Makefile @@ -304,7 +304,7 @@ tests = tst-attr1 tst-attr2 tst-attr3 tst-default-attr \ tst-thread_local1 tst-mutex-errorcheck tst-robust10 \ tst-robust-fork tst-create-detached tst-memstream -tests-internal := tst-typesizes \ +tests-internal := tst-typesizes tst-offsets \ tst-rwlock19 tst-rwlock20 \ tst-sem11 tst-sem12 tst-sem13 \ tst-barrier5 tst-signal7 tst-mutex8 tst-mutex8-static \ diff --git a/nptl/tst-offsets.c b/nptl/tst-offsets.c new file mode 100644 index 0000000..1aa8a0e --- /dev/null +++ b/nptl/tst-offsets.c @@ -0,0 +1,41 @@ +/* Check pthread internal offsets. + Copyright (C) 2017 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
