This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

Zero initialize engine_fns entirely at creation, then override those
fields we intend to use, rather than zero just initializing the unused
fields later on.
There should be no user visible changes after this commit.

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.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
|

If the user passed in values outside the range of [0, MAX_NR_PROCESSORS),
it would cause the code to access out-of-bind engine function pointers.
Add some asserts to catch that and to fix the related compiler warnings.

The sim-basics.h is too big and includes too many things. This leads
to some arch's sim-main.h having circular loop issues with defs, and
makes it hard to separate out common objects from arch-specific defs.
By splitting up sim-basics.h and killing off sim-main.h, it'll make
it easier to separate out the two.

This function has done only one thing: post-process command line
settings to see if profiling or tracing has been enabled, and if
so, set the run_fast_p flag in the simulator state. That flag is
only used in one place: to select the fast or slow cgen engine.
By inlining the run_fast_p logic to the one place it's used, we
can delete a good amount of logic specific to cgen ports: both
the call to cgen_init and the conditional simulator state. This
in turn allows us to have a single simulator state struct across
all ports so we can share objects more between them, and makes
the sim_open calls look more consistent.

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.

gdb/ChangeLog:
Update copyright year range in all GDB files.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

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.

Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
