This old port setup its own uintXX types, but since we require C11
now, we can assume the standard uintXX_t types exist and use them.
|
|
Now that all ports have migrated to the new framework, drop support
for the old sim_state_base layout.
|
|
Currently all ports have to declare sim_state themselves in their
sim-main.h and then embed the common sim_state_base & sim_cpu in it.
This dynamic makes it impossible to share common object code among
multiple ports because the core data structure is always different.
Let's invert this relationship: common code declares sim_state, and
if the port actually needs state on a per-instance basis, it can use
the new arch_data field for it. Most ports don't actually use it,
so they don't need to declare anything at all.
This is the first in a series of changes: it adds a define to select
between the old & new layouts, then converts all the ports that don't
need custom state over to the new layout.

The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.

We build & bundle the watchpoint module everywhere, but we don't make
the command line flags available by default. A few targets opted in,
but most did not. Just enable the flag for everyone. Not all targets
will respect the flags (making them nops), but shouldn't be a big deal.
This is how we handle other common modules already.
|
|
This was dropped from the sim core in 1997, so no point in having these
sim ports continue to define it.
|
|
Having this be a config option doesn't make sense: the code size is
pretty much the same (as all the logic is still active), and if it's
disabled, the sim throws an error if you try to use it. That means
we can't break sims that weren't using it before by enabling it all
the time.
|
|
Since every target typedefs this the same way, move it to the common code.
We have to leave Blackfin behind here for now because of inter-dependencies
on types and headers: sim-base.h includes sim-model.h which needs types in
machs.h which needs types in bfim-sim.h which needs SIM_CPU.
|
|
Almost every target defines sim_cia the same way -- either using the
address_word type directly, or a type of equivalent size. The only
odd one out is sh64 (who has 32bit address_word and 64bit cia), and
even that case doesn't seem to make sense. We'll put off clean up
though of sh64 and at least set up a sensible default for everyone.
|
|
The CIA_{GET,SET} macros serve the same function as CPU_PC_{GET,SET}
except the latter adds a layer of indirection via the sim state. This
lets models set up different functions at runtime and doesn't reach so
directly into the arch-specific cpu state.
It also doesn't make sense to have two sets of macros that do exactly
the same thing, so lets standardize on the one that gets us more.
|
|
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.
|
|
Make cpu allocation fully dynamic so we can leverage the common
sim-cpu and its APIs.
