All funcs already call other funcs that don't return. The mips port is
the only exception because its generic exception handler can return in
the case of normal exceptions. So while the exceptions its signal handler
triggers doesn't return, we can't express that conditional logic. So add
some useless abort calls to make the compiler happy.

Clean up includes a bit by making ports include opcodes/ headers
explicitly. This matches other projects, and makes it more clear
where these headers are coming from.
|
|
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.

Move this out of the global sim-main.h and to the few files that
actually use functions from it. Only the cgen ports were pulling
this, so this makes cgen & non-cgen behave more the same.
|
|
The cgen-types.h header sets up types that are needed by cgen-defs.h,
so move the include out of sim-main.h and to that header. It might
be needed in other specific modules, but for now let's kick it out of
sim-main.h to make some progress. Things still build with just this.
|
|
Not all arches include this in sim-main.h, and the ones that do don't
actually use bfd defines in the sim-main.h header. Prune it to make
sim-main.h simpler so we can kill it off entirely in the future.
We add the include to the files that utilize e.g. bfd_vma though.
|
|
All ports should be migrated now. Drop the SIM_HAVE_COMMON_SIM_CPU
knob and require it be used everywhere now.
|
|
The cpu.h change is in generated cgen code, but that has been sent
upstream too, so the next regen should include it automatically.
|
|
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.
|
|
This hook doesn't return a value, so don't define it to 0 to avoid
the compiler warning about it not being used.
|
|
Some of these were missing includes, some were unused funcs we can
cleanup, and some were missing prototypes for use in other files.

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.

This helps us break up tconfig.h more. Any file using this define should
be pulling in sim-main.h already, so things should continue working.
|
|
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.
|
|
This is the only sim that sets up its own WITH_TRACE mask and it conflicts
with the user setting their own list at configure time. Drop it to match
all the other sims.
|
|
This doesn't appear to have been used since 1998, but wasn't cleaned
up since. So much for being "quick" ;).
|
|
Since every target typedefs this the same way, move it to the common code.
We have to leave Blackfin behind here for now because of inter-dependencies
on types and headers: sim-base.h includes sim-model.h which needs types in
machs.h which needs types in bfim-sim.h which needs SIM_CPU.
|
|
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.
|
|
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.
|
|
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.
|
|
This sets up the sim_state structure and the cpu member to match what we
do in most other sims, and what the common code suggests. This is a step
to unifying on the sim-cpu.o object.

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

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.
