This patch removes sparc32 and sparc32v9 sem_init arch specific implementation and set sparc32 to use nptl default one. The default implementation sets the required sem.newsem.pad to 0 (which is ununsed in other architectures). I checked on i686 and a sparc32v9 build. * nptl/sem_init.c (sem_init): Init pad value to 0. * sysdeps/sparc/sparc32/sem_init.c: Remove file. * sysdeps/sparc/sparc32/sparcv9/sem_init.c: Likewise. --- nptl/sem_init.c | 2 + sysdeps/sparc/sparc32/sem_init.c | 85 -------------------------------- sysdeps/sparc/sparc32/sparcv9/sem_init.c | 1 - 4 files changed, 8 insertions(+), 86 deletions(-) delete mode 100644 sysdeps/sparc/sparc32/sem_init.c delete mode 100644 sysdeps/sparc/sparc32/sparcv9/sem_init.c diff --git a/nptl/sem_init.c b/nptl/sem_init.c index be0f27d..9380a21 100644 --- a/nptl/sem_init.c +++ b/nptl/sem_init.c @@ -49,6 +49,8 @@ __new_sem_init (sem_t *sem, int pshared, unsigned int value) isem->data = value; #else isem->value = value << SEM_VALUE_SHIFT; + /* pad is used as a mutex on pre-v9 sparc and ignored otherwise. */ + isem->pad = 0; isem->nwaiters = 0; #endif diff --git a/sysdeps/sparc/sparc32/sem_init.c b/sysdeps/sparc/sparc32/sem_init.c deleted file mode 100644 index ae49ec5..0000000 --- a/sysdeps/sparc/sparc32/sem_init.c +++ /dev/null @@ -1,85 +0,0 @@ -/* Copyright (C) 2002-2016 Free Software Foundation, Inc. - This file is part of the GNU C Library. - Contributed by Ulrich Drepper , 2002. - - 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.
