ce39bd3890 sim: move many common settings from CPPFLAGS to config.h
Rather than stuffing the command line with a bunch of -D flags, start
moving things to config.h which is managed by autoheader.  This makes
the makefile a bit simpler and the build output tighter, and it makes
the migration to automake easier as there are fewer vars to juggle.

We'll want to move the other options out too, but it'll take more work.

e19418e02e sim: drop unused SIM_AC_OPTION_PACKAGES
This was imported from the ppc sim, but that was only used to control
a single file, and that is already governed by the hw models.  There's
no need to have a sep configure option here, especially since none of
the other sims are using it.  Even when the code is enabled, there's
no runtime overhead.

16f7876d71 sim: allow the environment configure option everywhere
Currently ports have to call SIM_AC_OPTION_ENVIRONMENT explicitly in
order to make the configure flag available.  There's no real reason
to not allow this flag for all ports, so move it to the common sim
macro.  This way we get standard behavior across all ports too.

35656e9521 sim: allow the assert configure option everywhere
Currently ports have to call SIM_AC_OPTION_ASSERT explicitly in order
to make the configure flag available, which none of them do.  There's
no real reason to not allow this flag for all ports, so move it to the
common sim macro.  This way we get standard behavior across all ports.

99d8e87993 sim: drop targ-vals.def->nltvals.def indirection
We don't have alternative nltvals.def files, so always symlinking
the targ-vals.def file to it doesn't gain us anything.  It does
make the build more complicated though and a pain to convert to
something newer (like automake).  Drop the symlinking entirely.

In the future, we'll want to explode this file anyways into the
respective arch dirs so things can be selected dynamically at
runtime, so it's not like we'll be bringing this back.

0dc73ef7c3 sim: drop --enable-sim-{regparm,stdcall} options
These options were never exposed for most sims (just the ppc one),
and they are really only useful on 32-bit x86 systems.  Considering
modern systems tend to be 64-bit x86_64 and how well modern compilers
are at optimizing code, these have outlived their usefulness.

22be3fbeac sim: drop --enable-sim-cflags option
No other sub directory provides such a configuration option, so
drop it from the sim dir as well.  This cleans up a good bit of
code in the process.

If people want to use custom flags for just the sim, they can
still run configure+make by hand in the sim subdir and use the
normal CFLAGS settings.

936df7568a sim: drop common/cconfig.h in favor of a single config.h
The common subdir sets up a cconfig.h file to hold checks for the common
code.  In practice, most files still end up using config.h instead which
just leads to confusion.

Merge all the configure checks that went into cconfig.h into SIM_AC_COMMON
so we can drop the cconfig.h file altogether.  Now there is only a single
config.h file like normal.

9bbf6f91c6 sim: punt x86-specific bswap logic
The compiler/C library should produce reasonable code for htonl/ntohl,
and at least glibc tries pretty hard to always produce good code for
them.  This logic only had support for 32-bit x86 systems anymore, and
it's unlikely people were even opting into this, so drop it all.

0cb8d8513c sim: drop host endian configure option
The --enable-sim-hostendian flag was purely so people had an escape route
for when cross-compiling.  This is because historically, AC_C_BIGENDIAN
did not work in those cases.  That was fixed a while ago though, so we can
require that macro everywhere now and simplify a good bit of code.

1ac72f0659 sim: convert to bfd_endian
Rather than re-invent endian defines, as well as maintain our own list
of OS & arch-specific includes, punt all that logic in favor of the bfd
ones already set up and maintained elsewhere.  We already rely on the
bfd library, so leveraging the endian aspect should be fine.

The iq2000/m32r/sh64 option parsing logic appears to have always been
dead.  At least iq2000/sh64 are simply copy & paste rot from m32r.

The lm32 option parsing hack here hasn't been needed for a while -- this
was fixed back in commit 11409fac6b in the
common code.

d47f5b30d8 sim: delete dead current_state globals
The global current_state handle to the current simulator state is a
design idea that was half implemented, but never really cleaned up.
The point was to have a global variable pointing to the state so that
funcs could more quickly & easily access the state anywhere.  We've
instead moved in the direction of passing state around everywhere and
don't have any intention of moving back.

I also can't find any references to gdb using this variable, or to
cgen related "dump_regs" functions, both of which were used in the
comments related to this code.

5e744ef887 sim: unify sim-hload
Pretty much all targets are using this module already, so add it to the
common list of objects.  The only oddball out here is cris and that's
because it supports loading via an offset for all the phdrs.  We drop
support for that.

1b393626ce sim: punt WITH_DEVICES & tconfig.h support
No arch is using this anymore, and we want all new ports using the
hardware framework instead.  Punt WITH_DEVICES and the two callbacks
device_io_{read,write}_buffer.

We can also punt the tconfig.h file as no port is using it anymore.
This fixes in-tree builds that get confused by picking up the wrong
one (common/ vs <port>/) caused by commit ae7d0cac8c.

Any port that needs to set up a global define can use their own
sim-main.h file that they must provide regardless.

0e9672991e sim: standardize sim_create_inferior handling of argv a bit more
For targets that process argv in sim_create_inferior, improve the code:
- provide more details in the comment
- make the check for when to re-init more robust
- clean out legacy sim_copy_argv code

This will be cleaned up more in the future when we have a common inferior
creation function, but at least help new ports get it right until then.

0d58595077 sim: sim-model: build for everyone
Rather than include this for some targets, set it up so we can build it
all the time via the common code.  This makes it easier for targets to
opt into it when they're ready, increases build coverage, and allows us
to centralize much of the logic.

We also get to delete tconfig.h from two more targets -- they were
setting WITH_DEVICES to 0 which has the same behavior as not defining
it at all.

While the SIM_HAVE_MODEL knob is gone, we now have WITH_MODEL_P, but it
is only used by the common sim-model code.  We use it to declare dummy
model lists when the arch hasn't created its own.

8a0ebee658 sim: move MACH/MODEL types into SIM_xxx namespace
The "MACH" and "MODEL" names are a bit generic and collide with symbols
used by other sections of code (like h8300's opcodes).  Since these are
sim-specific types, they really should have a "SIM_" prefix.

269362117d sim: make LMA loading the default for all targets

a few, this means the default changes from loading VMA to LMA.  It's
better to have the different targets be consistent, and allows some
code clean up.

cec1974488 sim: delete old breakpoint code
This code relies on the old sim-break module, but that was deleted in 2003.
The module only existed for gdb to tell the sim to set breakpoints on its
behalf, but then that logic was abandoned in favor of gdb knowing all about
proper breakpoints (since it does already for non-sim targets).  Some dead
code lived on in the older ports though -- clean it up now.

84e8e361dd sim: enable watchpoint module everywhere
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.

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.

db7858e227 sim: cgen: namespace custom trace functions
The cgen code declares some macros/funcs using the trace_xxx prefix, but
the code isn't generic and only works with cgen targets.  This is blocking
the creation of new common trace functions.

Let's blindly add cgen_xxx prefixes to all these symbols.  Some already
use this convention to avoid conflicts, so it makes sense to align them.
In the future we might want to move some to the common trace core, but
one thing at a time.

20bca71d82 sim: unify SIM_CPU definition
Since every target typedefs this the same way, move it to the common code.

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.

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.

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 4th parameter of the AC_ARG_ENABLE macro to fix it.

This was caused by the simplification work in 1517bd2742.
