//@PURPOSE: Provide implementations of atomic operations for PowerPC/AIX-32bit.
//
//@CLASSES:
// bsls::AtomicOperations_POWERPC32_AIX_XLC: atomics for PPC32/AIX.
//
//@DESCRIPTION: This component provides classes necessary to implement atomics
// on the AIX PowerPC platform in 32bit mode with the xlC compiler. The
// classes are for private use only. See 'bsls_atomicoperations' and
// 'bsls_atomic' for the public interface to atomics.
