Mike Frysinger 13a590ca65 sim: use ARRAY_SIZE instead of ad-hoc sizeof calculations 2017-02-13 01:26:21 -05:00
Joel Brobecker 61baf725ec update copyright year range in GDB files
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

gdb/ChangeLog:

        Update copyright year range in all GDB files.

Mike Frysinger 2e3d4f4d5d sim: sim_{create_inferior,open,parse_args}: constify argv/env slightly
2016-01-03  Mike Frysinger  <vapier@gentoo.org>

	* sim-options.c (sim_parse_args): Mark argv array const.
	* sim-options.h (sim_parse_args): Likewise.

Mike Frysinger 77cf2ef5dc sim: parse_args: display getopt error ourselves
Fix a long standing todo where we let getopt write directly to stderr
when an invalid option is passed.  Use the sim io funcs instead as they
go through the filtered callbacks that gdb wants.

Mike Frysinger b3fbb288af sim: cris: use standard output helpers
The sim-io module provides output helpers, so no need to define local
ones anymore.

Mike Frysinger d47f5b30d8 sim: delete dead current_state globals
The global current_state handle to the current simulator state is a
design idea that was half implemented, but never really cleaned up.
The point was to have a global variable pointing to the state so that
funcs could more quickly & easily access the state anywhere.  We've
instead moved in the direction of passing state around everywhere and
don't have any intention of moving back.

I also can't find any references to gdb using this variable, or to
cgen related "dump_regs" functions, both of which were used in the
comments related to this code.

Mike Frysinger 5e744ef887 sim: unify sim-hload
Pretty much all targets are using this module already, so add it to the
common list of objects.  The only oddball out here is cris and that's
because it supports loading via an offset for all the phdrs.  We drop
support for that.

Mike Frysinger 8b494522f9 sim: cris: do not pass cpu when writing memory during init
The point of passing down the cpu to core reads/writes is to signal which
cpu is making the access.  For system accesses (such as internal memory
initialization), passing the cpu down doesn't make sense, and in the case
of early init like cris, can cause crashes.  Since the cpu isn't fully set
up at this point, if the core code tries to access some fields (like the
PC reg), it'll crash.  While cris shouldn't be doing this setup here (it
should be in the inferior stage), we'll deal with that later.

Mike Frysinger 0e9672991e sim: standardize sim_create_inferior handling of argv a bit more
For targets that process argv in sim_create_inferior, improve the code:
- provide more details in the comment
- make the check for when to re-init more robust
- clean out legacy sim_copy_argv code

This will be cleaned up more in the future when we have a common inferior
creation function, but at least help new ports get it right until then.

Mike Frysinger 34cf511206 sim: cris: migrate from WITH_DEVICES to WITH_HW
The cris port was using the device framework to handle two addresses when
the --cris-900000xx flag was specified.  That can be implemented using the
newer hardware framework instead which allows us to drop the device logic
entirely, as well as delete the tconfig.h file.  Basically we create a new
cris_900000xx device model and move the read logic out of devices.c and
into that.  The rest of the devices logic was callback to the hardware
framework already.

Mike Frysinger 9db2b71908 sim: cris: move option install to sim_open
We've moved custom option install for other targets to sim_open, so update
cris too.  It's the last one using MODULE_LIST, so we can drop that from
the common code too.

Mike Frysinger 6e4f085c7f sim: sim-close: unify sim_close logic
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.

Mike Frysinger b2b255bdf3 sim: constify prog_name
There's no need for the prog_name handed down to the core to be mutable,
so add const markings to it and all the related funcs.

Joel Brobecker 8acc9f485b Update years in copyright notice for the GDB 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.

Mike Frysinger 2419798b80 sim: start a unified sim_do_command
Since sim_do_command for many people simply calls sim_args_command, start
a unified version of it.  For people who handle their own options, they
could switch to this by using sim_add_option_table instead.
