Mike Frysinger e8713c0f02 sim: d10v: link in missing testsuite
Looks like historical restructuring in this dir lost the d10v-elf subdir
and no one noticed in the meantime.  Re-add it to the testsuite.

There are some failures, but better some tests get run than none at all.

Mike Frysinger 247ac9ee6e sim: cr16: 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.

Mike Frysinger 4b0cc5edf4 sim: cr16: delete NEED_UI_LOOP_HOOK handling
This hook is used only when linked into gdb, and cr16 doesn't have a gdb
port anymore.  Punt it.

Mike Frysinger 1e504675bd sim: cr16: delete dead code
This code is getting in the way of porting to nrun, so just drop it.
If anyone actually cares about this cpu, they can revive it.

In preparation for converting to nrun, call the common functions that
are needed.  This doesn't produce any new warnings, and the generated
code should be the same.

Mike Frysinger 4daf7a7c3a sim: cr16: add _start symbol to tests [BZ #12385]
The current cr16 testsuite sets up _START, but the linker looks for the
_start symbol.  Add the latter as an alias to the former.

Mike Frysinger 2b4bc832a7 sim: microblaze: convert to nrun
This port already was storing its cpu state in the sim_cpu structure, so
converting it over was pretty easy.  It is allocating memory itself still,
but we'll fix that up in the future at some point.

Mike Frysinger 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.

Mike Frysinger 191ec03314 sim: microblaze: start a testsuite
Since the sim doesn't have any debug support in it, we can only exit
cleanly.  But this is still better than nothing.

Change the default microblaze sim to not dump the debug load output
when running.  No other does this, and it breaks the testsuite.

Mike Frysinger 744b9a190b sim; testsuite: allow tests to set no output
If a test doesn't write anything at all to stdout, the current test
framework can't support that.  Even if you put a blank output line:
	# output:
the setup happily clobbers that with a default pass/fail string.

Tweak the parsing logic so we only set the output to pass/fail when
the test has no output marker.

Mike Frysinger 92fc6153a6 sim: common: sim-arange: fix extern inline handling
With newer versions of gcc (5.x), the extern inline we're using with the
sim-arange module no longer works.  Since this code really wants the gnu
inline semantics, use that attribute explicitly.

Mike Frysinger 6dae8a88bf sim: testsuite: make subdir unconditional
Since the testsuite subdir has to handle dynamic arch values already,
there's no real value in requiring arches to opt in to it.  Most have
a testsuite now anyways, and we're requiring it in the future.

Mike Frysinger 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.

The build line was missing the normal BUILD_xxx flags.  Once we added
that, we get warnings that weren't shown before.  As we fix those, we
notice that the -d option segfaults because it tries to write readonly
memory.  Fix that too as part of the const/prototype clean up.

Mike Frysinger 05f53ed611 sim: m68hc11/mips/mn10300/v850: add basic sim_pc_get
The previous profile change broke these sims that use sim-profile but
not sim-cpu (due to missing model support).  Add simple funcs until we
can convert these over properly.

Mike Frysinger 596f88276c sim: profile: disconnect from watchpoint core
The profile code was using STATE_WATCHPOINTS to get access to the PC, but
we already have a standard method for getting the pc, so switch to that.

This assumes that sizeof_pc is the same size as sim_cia, but we already
assume this in places by way of sim_pc_{get,set}, and this is how it's
documented in the sim-base.h API.

Mike Frysinger 97f478c5a4 sim: Revert "Fix frv/iq2000/m32r/sh64 sim, default hardware to off."
This partially reverts commits:
	105dd264de
	3df3af7c3f
	c4892a6b37
	9e3042ec07

Now that dv-sockser is handled entirely by the common build logic, the
failure these targets were hitting isn't really possible anymore.  Lets
reset their hardware status back to defaulting to on.  Some of these
were set to "always" previously, but we don't support that anymore.

Mike Frysinger 30452bbe7e sim: fix sim-hardware configure option
The current default handling for the --enable-sim-hardware option ends up
forcing the value to whatever is set as the first argument when calling
the macro (by virtue of how autoconf works).  Relocate the setup code to
the 4th parameter of the AC_ARG_ENABLE macro to fix it.

This was caused by the simplification work in 1517bd2742.

Mike Frysinger 64dd13dfc2 sim: drop support for requiring hw support
Since no sim is using the "always" option to SIM_AC_OPTION_HARDWARE, and
we don't want to require hw support to always be enabled, drop the option.
This leads to a slight simplification in the macro too as we can collapse
the sim_hw_p variable.

Mike Frysinger c906b4b52b sim: frv: delete UART device support
This looks like copy & paste logic from the m32r port (and history
suggests this as well).  Since building with hw & device support
enabled leads to failures:
sim/frv/devices.c: In function 'device_io_read_buffer':
sim/frv/devices.c:39:15: error: 'UART_INCHAR_ADDR' undeclared (first use in this function)

Delete it entirely.  We leave device support in place as it is used
to flush the scache.

Mike Frysinger 49cd1634b2 sim: dv-sockser: move build to common dir
If dv-sockser is available, lets add it to the common SIM_HW_OBJS
variable so it is always included automatically.  Now ports do not
have to shoe horn it in directly themselves.  It does mean it will
be compiled for targets that don't explicitly use it, but that's
really what we want anyways.

Mike Frysinger 3649cb0656 sim: dv-sockser: add stub funcs when not available
This lets ports assume that the dv-sockser API is always available if

and it makes the resulting code a bit simpler.
