This adds the OpenRISC 32-bit sim target. The OpenRISC sim is a CGEN
based sim so the bulk of the code is generated from the .cpu files by
CGEN. The engine decode and execute logic in mloop uses scache with
pseudo-basic-block extraction and supports both full and fast (switch)
modes.
The sim does not implement an mmu at the moment. The sim does implement
fpu instructions via the common sim-fpu implementation.

FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.
Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

Previously this used the error function from GDB directly when linked
against GDB instead of the error method in the host callbacks
structure. This was exposed via a link error when GDB was converted
to C++. The error function invokes the error callback similar to
sim_io_error.
Note that there are also error functions in sim/ppc/main.c and
sim/ppc/misc.c. The ppc libsim.a expects each consumer to provide
several symbols used by the library including "error". sim-calls.c
provides these symbols when the library is linked into gdb. The dgen,
igen, tmp-filter, tmp-ld-decode, tmp-ld-cache, and tmp-ld-insn programs
use the functions from misc.c. psim uses the functions from main.c.

* sim_calls.c (error): New function.
Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only. However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd. This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).

When building for mipstx39-rtems4.12 targets, some funcs use SD and CPU
implicitly. Restore the defines for these to the local sd and cpu vars.
This was broken by the clean up in commit d47f5b30d8.
Reported-by: Joel Sherrill <joel.sherrill@oarcorp.com>
The common sim tracing code already handles loading and tracking of
symbols from the target program so that it can show symbol info in
trace/disassembly calls. Once we touch up the trace code and add a
few API callbacks, ports don't need to do loading and searching of
symbol tables themselves anymore.
A few funcs are only used locally, so mark them static to avoid warnings
due to -Wmissing-prototypes.
Some funcs cast the return value wrong, so drop them (and let void * just
work by default).
Update some prototypes to be new style.
The current machs.h mixes common enums with Blackfin-specific defines.
This causes us troubles with header inclusion order such that we can't
drop the old SIM_CPU typedef (which is duplicated in common code). By
splitting the two up, we can unwind this dependency chain, and drop the
old typedef. It also fixes building with older gcc versions.

The mips bfd will sign extend 32-bit addresses into 64-bit values,
so if the entry happens to be 0x80000000 or higher, it is turned to
0xffffffff80000000 which points to memory that doesn't exist.
This wasn't an issue until commit 26f8bf63bf
as all addresses were automatically truncated there in the translate
function to 32-bits. When we cleaned up that code, the full 64-bits
were checked leading to many test failures for mips-sde-elf targets
and such.
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.
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.
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.
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.
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.
No other port calls this macro directly, and mips has it hardcoded
to the default -- disabling smp. In the future we'll enable this
for all targets in common code, so tidy up the mips code now.
Currently ports have to call SIM_AC_OPTION_INLINE 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.
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.
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.
Now that cconfig.h doesn't exist, there's no need to build in the common
subdir anymore. We leave the configure/Makefile files in there as there
is a helper for developers to generate the nltvals.def file. Once that
gets cleaned up in the future though, we can drop the build logic too.
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.
Some targets have started to add support for calling the disassembler
automatically when executing code. Add support for that directly into
the trace core.
