-/* Simulator state pseudo baseclass.
-
-   Each simulator is required to have the file ``sim-main.h''.  That
-   file includes ``sim-basics.h'', defines the base type ``sim_cia''
-   (the data type that contains complete current instruction address
-   information), include ``sim-base.h'':
-
-     #include "sim-basics.h"
-     typedef address_word sim_cia;
-     /-* If `sim_cia' is not an integral value (e.g. a struct), define
-         CIA_ADDR to return the integral value.  *-/
-     /-* #define CIA_ADDR(cia) (...) *-/
-     #include "sim-base.h"
-   
-   finally, two data types `struct _sim_cpu' and `struct sim_state'
-   are defined:
-
-     struct _sim_cpu {
-        ... simulator specific members ...
-        sim_cpu_base base;
-     };
-
-     struct sim_state {
-       sim_cpu cpu[MAX_NR_PROCESSORS];
-     #if (WITH_SMP)
-     #define STATE_CPU(sd,n) (&(sd)->cpu[n])
-     #else
-     #define STATE_CPU(sd,n) (&(sd)->cpu[0])
-     #endif
-       ... simulator specific members ...
-       sim_state_base base;
-     };
-
-   Note that `base' appears last.  This makes `base.magic' appear last
-   in the entire struct and helps catch miscompilation errors. */
