From e4720b0e594f4599d0256dfb713ddd4d2281ddbc Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Wed, 15 Aug 2007 20:47:43 +0000 Subject: * sysdeps/sparc/fpu/fraiseexcpt.c (__feraiseexcept): Fix raising FE_UNDERFLOW on Niagara CPUs. * sysdeps/sparc/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions. * sysdeps/unix/sysv/linux/sparc/internaltypes.h (sparc_new_sem, sparc_old_sem): New structs. * sysdeps/unix/sysv/linux/sparc/sparc32/sem_wait.c (__sem_wait_cleanup): New function. (__new_sem_wait): Use sparc_new_sem structure. Bump and afterwards decrease nwaiters. Register __sem_wait_cleanup as cleanup handler. Pass isem->private ^ FUTEX_PRIVATE_FLAG as last argument to lll_futex_wait. (__old_sem_wait): New function. * sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/sem_wait.c: Include nptl/sysdeps/unix/sysv/linux/sparc version. * sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/sem_timedwait.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/sem_post.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sem_trywait.c (__new_sem_trywait): Use sparc_old_sem structure. * sysdeps/unix/sysv/linux/sparc/sparc32/sem_timedwait.c (sem_timedwait): Use sparc_new_sem structure. Bump and afterwards decrease nwaiters. Register __sem_wait_cleanup as cleanup handler. Pass isem->private ^ FUTEX_PRIVATE_FLAG as last argument to lll_futex_timed_wait. * sysdeps/unix/sysv/linux/sparc/sparc32/sem_post.c (__new_sem_post): Use sparc_new_sem structure. Only wake if nwaiters > 0. Pass isem->private ^ FUTEX_PRIVATE_FLAG as last argument to lll_futex_wake. (__old_sem_post): New function. * sysdeps/unix/sysv/linux/sparc/sem_wait.c: New file. * sysdeps/unix/sysv/linux/sparc/sem_init.c: New file. * sysdeps/unix/sysv/linux/sparc/sem_timedwait.c: New file. * sysdeps/unix/sysv/linux/sparc/sem_post.c: New file. * sysdeps/unix/sysv/linux/sparc/sparc32/sparcv9/sem_init.c: Remove. * sysdeps/unix/sysv/linux/sparc/sparc32/sem_init.c: Remove. 2007-08-15 Jakub Jelinek * sysdeps/sparc/fpu/fraiseexcpt.c (__feraiseexcept): Fix raising FE_UNDERFLOW on Niagara CPUs. * sysdeps/sparc/fpu/feholdexcpt.c (feholdexcept): Clear all exceptions. --- sysdeps/sparc/fpu/feholdexcpt.c | 6 +++--- sysdeps/sparc/fpu/fraiseexcpt.c | 8 ++++---- 2 files changed, 7 insertions(+), 7 deletions(-) (limited to 'sysdeps/sparc') diff --git a/sysdeps/sparc/fpu/feholdexcpt.c b/sysdeps/sparc/fpu/feholdexcpt.c index 729637ad1b..424855e761 100644 --- a/sysdeps/sparc/fpu/feholdexcpt.c +++ b/sysdeps/sparc/fpu/feholdexcpt.c @@ -1,5 +1,5 @@ /* Store current floating-point environment and clear exceptions. - Copyright (C) 1997, 1998, 2005 Free Software Foundation, Inc. + Copyright (C) 1997, 1998, 2005, 2007 Free Software Foundation, Inc.
