7eed1055b8 sim: mcore: pull cpu state out of global scope
This avoids using global variables to hold the cpu state so we can
better integrate with the sim common code.

There's also a minor fix here where we move the pc register back into
the state that is accessible by the asints array.  When it was pulled
out previously, the reg store/fetch functions broke, but no one really
noticed as the mcore gdb port was dropped a while back.

9ef4651c49 sim: mcore: switch to common sim-reg
This is not entirely useful as mcore doesn't (yet) store its register
state in the cpu state, but it does allow for switching to the common
code for these functions.

02962cd9ea sim: mcore: convert to common reason/resume logic
Switch over to the common event loop logic so we don't have to maintain
the exception/exit logic ourselves.

6e4f085c7f sim: sim-close: unify sim_close logic
Other than the nice advantage of all sims having to declare one fewer
common function, this also fixes leakage in pretty much every sim.
Many were not freeing any resources, and a few were inconsistent as
to the ones they did.  Now we have a single module that takes care of
all the logic for us.

Most of the non-cgen based ones could be deleted outright.  The cgen
ones required adding a callback to the arch-specific cleanup func.
The few that still have close callbacks are to manage their internal
state.

We do not convert erc32, m32c, ppc, rl78, or rx as they do not use
the common sim core.

7d5c6c43ca sim: syscall: add common sim_syscall helpers
Many ports have the same sim syscall logic, so add some helpers to handle
all the common details.  The arches still have to deal with the unpacking
and packing of the syscall arguments, but the rest of the sim<->callback
glue is now shared.

61a0c964e6 sim: syscall: unify memory helpers

43236bb255 sim: mcore: clean up printf warnings
These printf statements are showing "word" objects which are typedefed
from long, so make sure to use l with %x when printing them to avoid
warnings from gcc.

f63036b811 sim: mcore: convert to common memory/verbose functions
Re-use the existing memory core that handles reads/writes.

The verbose command is converted to the common --verbose flag
since only a few call sites use it now.

e53e5aab53 sim: mcore: drop watchpoint/dumpmem/clearstats support
In preparation for converting to the common memory framework, the custom
commands get in our way.  But when we realize that gdb support has been
dropped for mcore, it makes things a bit easier: the main runner does not
let you run arbitrary commands once simulation starts.

So lets disable watchpoint support until it can be converted to the common
watchpoint logic.  There's already an ifdef to let us do that.

We straight up drop support for the dumpmem command (no other sim supports
this, and if it's a feature people want, we can add a common func) and the
clearstats command (not a big deal -- just restart your simulation).

We leave in place the verbose check points as a follow up commit will cut
that over to common logic.

767e68f1b9 sim: mcore: switch to common syscall handling
Now that libgloss has a header tracking the syscalls for this arch, we
can update the database to include it for the symbolic constants/maps.
Then we can switch the mcore syscall callbacks over to the common ones.

034685f9ce sim: replace CIA_{GET,SET} with CPU_PC_{GET,SET}
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.

97eca187b3 sim: mcore/microblaze: delete dead code
The mcore port had a few structs/defines that were never used.

Similarly, the microblaze port, because it was copied from mcore, has
that same dead code, and more.  The watchpoint logic was never actually
used.  Punt it all.

ea6b7543b4 sim: mcore: convert to nrun
A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point.  But at least this
is an improvement on the status quo.

aac18a6996 sim: mcore: drop sbrk support
The sbrk syscall assumes the sbrk region starts after the bss and the
current implementation requires a bss section to exist.  Since there
is no requirement for programs to have a bss in general, we want to
drop this check.  However, there is still the sbrk syscall that wants
to know about the region.

Since libgloss doesn't actually use the sbrk syscall (it implements
sbrk in its own way), and the sim really shouldn't enforce a specific
memory layout on programs, lets simply delete sbrk support.  Now it
always returns an error.

dc049bf460 sim: drop unused headers
These look like left over hacks from the days where we had to protect
ourselves from the compiler and C library.  None of these checks are
relevant, and we have common configure logic to do header tests.  Punt

ef3e8cf7d1 sim: delete duplicate SIGINT handling
Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:

  sigsave = signal (SIGINT, interrupt);

However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.
