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.
