// Alpha and PowerPC considerations
//
// Both the Alpha and the PowerPC do not guarantee that I/O to
// separate addresses will be executed in order. The Alpha and
// PowerPC differ, however, in that the PowerPC guarantees that
// output to the same address will be executed in order, while the
// Alpha may cache and 'collapse' consecutive output to become only
// one output.
//
// Consequently, we use the following synchronization macros. They
// are relatively expensive in terms of performance, so we try to avoid
// them whereever possible.
//
// CP_EIEIO() 'Ensure In-order Execution of I/O'
// - Used to flush any pending I/O in situations where we wish to
// avoid out-of-order execution of I/O to separate addresses.
//
// CP_MEMORY_BARRIER()
// - Used to flush any pending I/O in situations where we wish to
// avoid out-of-order execution or 'collapsing' of I/O to
// the same address. On the PowerPC, this will be defined as
// a null operation.
