This commit:
commit ef9866970c
Date: Thu Mar 28 06:40:30 2019 +0900
sim/common: convert sim-arange to use sim-inline
broke many simulator targets. I fixed aarch64 in a previous commit
without realising how many other target were also broken.
This commit adds the missing includes (sim-assert.h and libiberty.h),
which seem to be needed by many simulator targets, in a central
location, this should fix most builds.
sim/common/ChangeLog:
* sim-base.h: Add 'sim-assert.h' include.
* sim-basics.h: Add 'libiberty.h' include.

/* 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. *-/
|
|
/-* typedef struct {...} sim_cia; *-/
|
|
/-* #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];
|
|
... 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. */
