-/* This file contains a complete ARMulator memory model, modelling a
-"virtual memory" system. A much simpler model can be found in armfast.c,
-and that model goes faster too, but has a fixed amount of memory. This
-model's memory has 64K pages, allocated on demand from a 64K entry page
-table. The routines PutWord and GetWord implement this. Pages are never
-freed as they might be needed again. A single area of memory may be
-defined to generate aborts. */
