180d40b903 sim: avr: Fix 'multiple definition of sim_{read,write}'
This patch does whatever was done in
https://sourceware.org/ml/gdb-patches/2015-04/msg00437.html to fix
broken gdb build for the AVR target.

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.

248d23e82b sim: gennltvals.sh: handle split out newlib source tree
Since newlib no longer shares the same repo as binutils/gdb, we have to go
searching further afield to locate the sources.  We still look at the top
level for newlib, but if that is not found, we also try up one dir outside
of this source tree.  It sucks, but better than the status quo (no workie).

d3e9b40afb sim/erc32: Switched emulated memory to host endian order.
Change data ordering in emulated memory from target order (big endian)
to host order. Improves performance and simplifies most memory
operations. Requires some byte twisting during stores on little
endian hosts (intel). Also removed support for little-endian binaries.

3ebe2863f7 sim: clean up duplicate sim-engine hooks
Now that we've unified sim-cpu, we can delete the duplicate sim-engine
hooks -- these targets defined these only because they didn't fully
implement the sim-cpu callbacks.

e8d3a34fee sim: trim old USING_SIM_BASE_H define

20bca71d82 sim: unify SIM_CPU definition
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.

7e83aa92f2 sim: unify sim_cia definition
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.

c85fc61074 sim: microblaze: switch to common memory functions
Re-use the existing memory core that handles reads/writes.

This drops support for the dumpmem command, but gdb itself has
support for dumping memory regions.

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

Support for the clearstats command is dropped entirely, but no
other sim really does this, and the same thing can be done by
reloading.  If it's important (clearing cycle stats) to someone,
we can add a common function for it.

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.

do in most other sims, and what the common code suggests.  This is a step
to unifying on the sim-cpu.o object.

20cc975360 sim: moxie: fix running after nrun conversion
The nrun conversion was slightly incorrect in how it stopped when an
exception occurred.  We still set cpu.asregs.exception, but nothing
was checking it anymore.  Convert all of that to sim_engine_halt.

To keep things from regressing again, add a basic testsuite too.

b366059a5b sim: d10v: fix signal updates
Way back in aba6488e0b, a bunch of signal
defines were changed to TARGET_SIGNAL_xxx.  For d10v, the transition was
incomplete which lead to sim_stop_reason using the new set but sim_resume
still using the old set.  Which meant in some cases, the sim would never
actually stop.

Convert all the remaining SIGxxx defines in here to TARGET_SIGNAL_xxx.
This has the nice side effect of fixing the testsuite.
