* csu/tst-atomic.c (do_test): Add some new
atomic_compare_and_exchange_val_acq, atomic_add_zero, atomic_compare_and_exchange_bool_acq and atomic_add_negative tests. * include/atomic.h (atomic_add_negative, atomic_add_zero): Prefix local variable so that it doesn't clash with the one in atomic_exchange_and_add. * sysdeps/ia64/bits/atomic.h (atomic_exchange): Fix for long/void * pointers. (atomic_exchange_and_add): Implement using __sync_fetch_and_add_?i. * sysdeps/powerpc/bits/atomic.h (atomic_exchange_and_add): Force value into register. * sysdeps/s390/bits/atomic.h (__arch_compare_and_exchange_val_64_acq): Cast newval to long. * sysdeps/x86_64/bits/atomic.h (__arch_compare_and_exchange_val_64_acq): Cast newval and oldval to long. (atomic_exchange): Cast newvalue to long if sizeof == 8. (atomic_exchange_and_add): Cast value to long if sizeof == 8. (atomic_add, atomic_add_negative, atomic_add_zero): Likewise. (atomic_bit_set): Shift 1L up in all cases to shut up warnings.
