* sysdeps/sparc/fpu/fraiseexcpt.c (__feraiseexcept): Fix raising cvs/fedora-glibc-20070815T2049
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.
