/* 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"
|
|
|
|
/-* If `sim_cia' is not an integral value (e.g. a struct), define
|
|
|
|
CIA_ADDR to return the integral value. *-/
|
2015-04-18 10:08:56 +02:00
|
|
|
/-* typedef struct {...} sim_cia; *-/
|
1999-04-16 03:35:26 +02:00
|
|
|
/-* #define CIA_ADDR(cia) (...) *-/
|
|
|
|
#include "sim-base.h"

|
|
|
|
1999-04-16 03:35:26 +02:00
|
|
|
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 {
|
2010-02-04 23:52:03 +01:00
|
|
|
sim_cpu *cpu[MAX_NR_PROCESSORS];
|
1999-04-16 03:35:26 +02:00
|
|
|
... 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. */
