7b01c1cc1d sim: fixes for libopcodes styled disassembler
In commit:

  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.

e8f20a28b1 sim: split program path out of argv vector
We use the program argv to both find the program to run (argv[0]) and
to hold the arguments to the program.  Most of the time this is fine,
but if we want to let programs specify argv[0] independently (which is
possible in standard *NIX programs), this double duty doesn't work.

So let's split the path to the program to run out into a separate
field by itself.  This simplifies the various sim_open funcs too.

By itself, this code is more of a logical cleanup than something that
is super useful.  But it will open up customization of argv[0] in a
follow up commit.  Split the changes to make it easier to review.

fe7fdfda72 sim: clarify license text via COPYING file
The project has been using GPL v3 for a while now in the source files,
and the arm & ppc ports have carried a copy of the COPYING file.  Lets

Also drop the ppc/COPYING.LIB as it's not really referenced by any
source as everything is GPL v3.

b868a2393b sim: nltvals: localize TARGET_<open> defines
Code should not be using these directly, instead they should be
resolving these dynamically via the open_map.  Rework the common
callback code that was using the defines to use symbolic names
instead, and localize some of the defines in the ARM code (since
it's a bit unclear how many different APIs it supports currently),
then remove the defines out of the header so no new code can rely on
them.

9335d9f823 sim: rename ChangeLog files to ChangeLog-2021
Now that ChangeLog entries are no longer used for sim patches,
this commit renames all relevant sim ChangeLog to ChangeLog-2021,
similar to what we would do in the context of the "Start of New

The purpose of this change is to avoid people merging ChangeLog
entries by mistake when applying existing commits that they are
currently working on.

Also throw in a .gitignore entry to keep people from adding new
ChangeLog files anywhere in the sim tree.

36bb57e40c sim: drop configure scripts for simple ports
These ports only use the pieces that have been unified, so we can
merge them into the common configure script and get rid of their
unique one entirely.

subdir Makefiles, but the configure script portion is merged.

be0387eed0 sim: hw: rework configure option & device selection
The sim-hardware configure option allows builders to select a set of
device models to enable.  But this seems like unnecessary overkill:
the existence of individual device models doesn't affect performance
at all as they are only enabled at runtime if the config uses them,
and individually these are all <5KB a piece.  Stripping off a total
of ~50KB from a ~1MB binary doesn't seem useful, and it's extremely
unlikely anyone will ever bother.

So let's simplify the configure/make logic by turning sim-hardware
into a boolean option like many of the other sim options.  Any ports
that have unique device models will declare them in their Makefile
instead of at configure time.  This will allow us to (eventually)
unify the setting into the common dir.

f9a4d54332 sim: overhaul & unify endian settings management
The m4 macro has 2 args: the "wire" settings (which represents the
hardwired port behavior), and the default settings (which are used
if nothing else is specified).  If none are specified, the arch is
expected to support both, and the value will be probed based on the
user runtime options or the input program.

Only two arches today set the default value (bpf & mips).  We can
probably let this go as it only shows up in one scenario: the sim
is invoked, but with no inputs, and no user endian selection.  This
means bpf will not behave like the other arches: an error is shown
and forces the user to make a choice.  If an input program is used
though, we'll still switch the default to that.  This allows us to
remove the WITH_DEFAULT_TARGET_BYTE_ORDER setting.

For the ports that set a "wire" endian, move it to the runtime init
of the respective sim_open calls.  This allows us to change the
WITH_TARGET_BYTE_ORDER to purely a user-selected configure setting
if they want to force a specific endianness.

With all the endian logic moved to runtime selection, we can move
the configure call up to the common dir so we only process it once
across all ports.

The ppc arch was picking the wire endian based on the target used,
but since we weren't doing that for other biendian arches, we can
let this go too.  We'll rely on the input selecting the endian, or
make the user decide.

ba307cddcf sim: overhaul alignment settings management
Currently, the sim-config module will abort if alignment settings
haven't been specified by the port's configure.ac.  This is a bit
weird when we've allowed SIM_AC_OPTION_ALIGNMENT to seem like it's
optional to use.  Thus everyone invokes it.

There are 4 alignment settings, but really only 2 matters: strict
and nonstrict.  The "mixed" setting is just the default ("unset"),
and "forced" isn't used directly by anyone (it's available as a
runtime option for some ports).

The m4 macro has 2 args: the "wire" settings (which represents the
hardwired port behavior), and the default settings (which are used
if nothing else is specified).  If none are specified, then the
build won't work (see above as if SIM_AC_OPTION_ALIGNMENT wasn't
called).  If default settings are provided, then that is used, but
we allow the user to override at runtime.  Otherwise, the "wire"
settings are used and user runtime options to change are ignored.

Most ports specify a default, or set the "wire" to nonstrict.  A
few set "wire" to strict, but it's not clear that's necessary as
it doesn't make the code behavior, by default, any different.  It
might make things a little faster, but we should provide the user
the choice of the compromises to make: force a specific mode at
compile time for faster runtime, or allow the choice at runtime.
More likely it seems like an oversight when these ports were
initially created, and/or copied & pasted from existing ports.

With all that backstory, let's get to what this commit does.

First kill off the idea of a compile-time default alignment and
set it to nonstrict in the common code.  For any ports that want
strict alignment by default, that code is moved to sim_open while
initializing the sim.  That means WITH_DEFAULT_ALIGNMENT can be
completely removed.

Moving the default alignment to the runtime also allows removal
of setting the "wire" settings at configure time.  Which allows
removing of all arguments to SIM_AC_OPTION_ALIGNMENT and moving
that call to common code.

The macro logic can be reworked to not pass WITH_ALIGNMENT as -D
CPPFLAG and instead move it to config.h.

All of these taken together mean we can hoist the macro up to the
top level and share it among all sims so behavior is consistent
among all the ports.

Move the various platform tests up a level to avoid duplication
across the ports.  When building multiple versions, this speeds
things up a bit.

own the config.h entirely just yet -- we still have some tests
related to libraries that need consideration.

383861bd08 sim: invert sim_state storage
Currently all ports have to declare sim_state themselves in their
sim-main.h and then embed the common sim_state_base & sim_cpu 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_state, and
if the port actually needs state on a per-instance basis, it can use
the new arch_data field for it.  Most ports don't actually use it,
so they don't need to declare anything at all.

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.

6df01ab8ab sim: switch config.h usage to defs.h
The defs.h header will take care of including the various config.h
headers.  For now, it's just config.h, but we'll add more when we
integrate gnulib in.

This header should be used instead of config.h, and should be the
first include in every .c file.  We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h.  We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way.  Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.

f08708cbf5 sim: add ATTRIBUTE_PRINTF / ATTRIBUTE_NULL_PRINTF where necessary
I finally got the all-targets sim building with Clang, these are all the
instances where an ATTRIBUTE_PRINTF or ATTRIBUTE_NULL_PRINTF attribute
needed to be added to avoid errors like:

    /home/simark/src/binutils-gdb/sim/aarch64/../common/sim-profile.c:464:19: error: format string is not a string literal [-Werror,-Wformat-nonliteral]
        vfprintf (fp, fmt, ap);
                      ^~~
There are more fixes needed to get everything building, but adding these
attributes is trivial enough, so I send them all in a single patch.

Adding the format attributes introduces some format string errors when
building with GCC (because now format strings are checked), so
corresponding changes are needed to avoid breaking the build.  Other
than simple format string specified changes, there is this one:

    /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c: In function 'hw_event_queue_schedule':
    /home/simark/src/binutils-gdb/sim/aarch64/../common/hw-events.c:95:15: error: too many arguments for format [-Werror=format-extra-args]
       95 |         NULL, dummy);
          |               ^~~~~

We can fix it and avoid using a dummy variable by simply calling
hw_event_queue_schedule_tracef instead of
hw_event_queue_schedule_vtracef.

e7d8f1da71 Remove and modernize dependencies in sim
Some spots in the sim build used manual dependencies, and some spots
did a compilation by hand but did not use the automatic dependency
tracking code.  This patch fixes these spots.

I didn't touch ppc, because it doesn't use the common Makefile code.
I also didn't touch objects that are for the build machine, because
automatic dependencies don't work for those.

efd82ac7cb Require GNU make
GDB has required GNU make for quite some time, and this patch applies
this approach to the sim as well.  Requiring GNU make means that
automatic dependency tracking can be simple and reliable, and it also
makes other refactorings simpler.

1f195bc327 sim: use -Werror when probing for supported warning flags
When building with clang, we get:

    error: unknown warning option '-Wmissing-parameter-type' [-Werror,-Wunknown-warning-option]

This is because clang only warns by default when encountering an unknown
warning option, and the probe for supported warning flags is done
without -Werror.  All flags are therefore accepted by configure, but
then it breaks when actually compiling a source file with -Werror.

This is equivalent to this commit in gdb:

    3e019bdc20
    gdb: Use -Werror when checking for (un)supported warning flags

We then see some other compilation errors when building with clang and
-Werror, they can be dealt with later.
