8df77a27a3 sim: fully merge sim_cpu_base into sim_cpu 
Now that all ports have migrated to the new framework, drop support
for the old sim_cpu_base layout.  There's a lot of noise here, so
it's been split into a dedicated commit.

4a21ad1e76 sim: enable common sim_cpu usage everywhere 
All ports should be migrated now.  Drop the SIM_HAVE_COMMON_SIM_CPU
knob and require it be used everywhere now.

53891d9a7c sim: cgen: prep for inverting sim_cpu storage 
Some common cgen code changes to allow cgen ports to invert their
sim_cpu storage one-by-one.

ffeb72b44c sim: sim_cpu: invert sim_cpu storage 
Currently all ports have to declare sim_cpu themselves in their
sim-main.h and then embed the common sim_cpu_base in it.  This
dynamic makes it impossible to share common object code among
multiple ports because the core data structure is always different.

Let's invert this relationship: common code declares sim_cpu, and
the port uses the new arch_data field for its per-cpu state.

This is the first in a series of changes: it adds a define to select
between the old & new layouts, then converts all the ports that don't
need custom state over to the new layout.  This includes mn10300 that,
while it defines custom fields in its cpu struct, never uses them.

09d236daec sim: dv-core: add hw_detach_address method [PR sim/25211] 
The core device has an attach address method as the root of the tree
which calls out to the sim API.  But it doesn't have a corresponding
detach method which means we just crash if anything tries to detach
itself from the core.  In practice, the m68hc11 is the only model
that actually tries to detach itself on the fly, so no one noticed
earlier.

With this in place, we can delete the existing detach code from the
m68hc11 model since it defaults to "passthru" callback which will in
turn call the dv-core detach, and they have the same behavior -- call
the sim core API to detach from the address space.

Bug: https://sourceware.org/PR25211

c0c25232da sim: run: move linking into top-level 
Automake will run each subdir individually before moving on to the next
one.  This means that the linking phase, a single threaded process, will
not run in parallel with anything else.  When we have to link ~32 ports,
that's 32 link steps that don't take advantage of parallel systems.  On
my really old 4-core system, this cuts a multi-target build from ~60 sec
to ~30 sec.  We eventually want to move all compile+link steps to this
common dir anyways, so might as well move linking now for a nice speedup.

We use noinst_PROGRAMS instead of bin_PROGRAMS because we're taking care
of the install ourselves rather than letting automake process it.

63bf33ff90 sim: build: move install steps to the top-level

9146585a05 sim: build: remove various obsolete generation dep variables 
These manual settings were necessary when we weren't doing automatic
header dependency tracking.  That was changed a while ago, and we use
automake now to do it all for us.  As a result, many of these vars
aren't even referenced anymore.

Further, some of the source file generation (e.g. .c files, or igen,
or cgen outputs) were moved to the common automake build, and it takes
care of dependency tracking for us with the object files.

90db43bb03 sim: build: switch to libtool for linking

a1af8f405c sim: move common flags to default AM_CPPFLAGS 
Since all host files we compile use these settings, move them out of
libcommon.a and into the default AM_CPPFLAGS.  This has the effect of
dropping the custom per-target automake rules.  Currently it saves us
~150 lines, but since it's about ~8 lines per object, the overhead
will increase quite a bit as we merge more files into a single build.

This also changes the object output names, so we have to tweak the
rules that were pulling in the common objects when linking.

ca7b34c5be sim: common: remove unused include paths 
A bunch of these paths don't include any headers, and most likely
never will, so there's no real need to keep them.  This will let
us harmonize paths with the top-level Makefile more easily, which
will in turn make it easier to move more compile steps there.

fde7c6bf64 sim: split CPPFLAGS between build & host 
In order to merge more common/ files into the top-level, we need to
add more host flags to CPPFLAGS, and that conflicts with our current
use with build-time tools.  So split them apart like we do with all
other build flags to avoid the issue.

cb9d1609da sim/cgen: mask uninitialized variable warning in cgen-run.c 
I see an uninitialized variable warning (with gcc 9.3.1) from
cgen-run.c, like this:

  /tmp/build/sim/../../src/sim/cris/../common/cgen-run.c: In function ‘sim_resume’:
  /tmp/build/sim/../../src/sim/cris/../common/cgen-run.c:259:5: warning: ‘engine_fns$’ may be used uninitialized in this function [-Wmaybe-uninitialized]
    259 |    (* engine_fns[next_cpu_nr]) (cpu);
        |    ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  /tmp/build/sim/../../src/sim/cris/../common/cgen-run.c:232:14: note: ‘engine_fns$’ was declared here
    232 |   ENGINE_FN *engine_fns[MAX_NR_PROCESSORS];
        |              ^~~~~~~~~~

This is a false positive - we over allocate engine_fn, and then only
initialize the nr_cpus entries which we will later go on to use.

However, we can easily silence this warning by initializing the unused
entries in engine_fns to NULL, this might also help if anyone ever
looks at engine_fns in a debugger, it should now be obvious which
entries are in use, and which are not.

With this change the warning is gone.

There should be no change in behaviour with this commit.

babcfd7588 sim: Initialize pbb_br_* by default 
On the files generated by sim/common/genmloop.sh, variables pbb_br_type and
pbb_br_npc are declared uninitialized and passed to other functions in some
cases.  Despite that those are harmless, they will generate GCC warnings
("-Wmaybe-uninitialized").

This commit ensures that pbb_br_type and pbb_br_npc variables are
initialized to a harmless value.

96894c19ad sim: Suppress non-literal printf warning 
Clang generates a warning if the format string of a printf-like function is
not a literal ("-Wformat-nonliteral"). On the default configuration, it
causes a build failure (unless "--disable-werror" is specified).

To avoid this warning, this commit now uses vsnprintf to format error
message and pass the message to sim_engine_abort function with another
printf-style formatting.

This patch is mostly authored by Andrew Burgess and slightly modified by
Tsukasa OI.

25ae9e2659 sim: Make WITH_{TRACE,PROFILE}-based macros bool 
Clang generates a warning if there is an ambiguous expression (possibly a
bitwise operation (& or |), but a logical operator (&& or ||) is used;
"-Wconstant-logical-operand").  On the default configuration, it causes a
build failure (unless "--disable-werror" is specified).

This is caused by predicate macros that use the form (base_variable & flag).
Clang considers them as regular integer values (not boolean) and
generates that warning.

This commit makes Clang think those predicate macros to be boolean.

7aaf9c03d1 sim/common: Add ATTRIBUTE_PRINTF 
Clang generates a warning if the format string of a printf-like function is

causes a build failure (unless "--disable-werror" is specified).

To avoid warnings on the printf-like wrapper, it requires proper
__attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason.

This commit adds ATTRIBUTE_PRINTF to a printf-like function.

Like commit b82817674f, this replaces BFD_VMA_FMT "x" in sim/ with

  commit 60a3da00bd
  Date:   Sat Jan 22 11:38:18 2022 +0000

      objdump/opcodes: add syntax highlighting to disassembler output

I broke several sim/ targets by forgetting to update their uses of the
libopcodes disassembler to take account of the new styled printing.

These should all be fixed by this commit.

I've not tried to add actual styled output to the simulator traces,
instead, the styled print routines just ignore the style and print the
output unstyled.

bf484e9348 sim: Allow toggling of quiet NaN-bit semantics 
IEEE754-1985 specifies the top bit of the mantissa as an indicator
of signalling vs. quiet NaN, but does not define the precise semantics.
Most architectures treat this bit as indicating quiet NaN, but legacy
(pre-R6) MIPS goes the other way and treats it as signalling NaN.

This used to be controlled by a macro that was only defined for MIPS.
This patch replaces the macro with a variable to track the current
semantics of the NaN bit and allows differentiation between older
(pre-R6) and and newer MIPS cores.

4095db4c9c sim: fix mingw builds with replacement gnulib open 
The header shuffling in here broke the workaround for gnulib defining
"open".  Move it back before the sim-specific includes to fix.  This
is because the callback struct in the headers has an "open" member and
this file tries to call that.

de8a2781a5 sim: use ## for automake comments 
The ## marker tells automake to not include the comment in its
generated output, so use that in most places where the comment
only makes sense in the inputs.

20a8e078cc sim: reorder header includes 
We're including system headers after local headers in a bunch of
places, but this leads to conflicts when our local headers happen
to define symbols that show up in the system headers.

Use the more standard order of:
* config.h (via defs.h)
* system headers
* local library headers (e.g. bfd & libiberty)
* sim specific headers
