42a4f53d2b 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.

gdb/ChangeLog:

	Update copyright year range in all GDB files.

5357150c97 sim: unify symbol table handling
The common sim tracing code already handles loading and tracking of
symbols from the target program so that it can show symbol info in
trace/disassembly calls.  Once we touch up the trace code and add a
few API callbacks, ports don't need to do loading and searching of
symbol tables themselves anymore.

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.

402cf05346 sim: msp430: drop duplicate sim_load_file call
There's no need, or desire, to call sim_load_file from sim_open.  The
higher levels (gdb/run) take care of calling sim_load for us already.

70d3944832 sim: msp430: switch to common disassembler tracing
The output format is a bit different, but the new form matches all the
other trace lines.  Otherwise, it should be functionally equivalent.

5d01527536 sim: aarch64/msp430: fix disassembler usage
The disasm framework reserves the private_data field for the disassemblers
themselves, not for people who use the disassembler.  Instead, there is an
application_data field for callers such as the sim.  Switch to it to avoid
random corruption/crashes when the disassemblers use private_data.

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.

fa8f87e53b sim: trace: add a basic cpu register class
The bfin/msp430 ports already had trace logic set up for reading/writing
cpu registers, albeit using different unrelated levels (core & vpu).  Add
a proper register class for these and for other ports.

7d5c6c43ca sim: syscall: add common sim_syscall helpers
Many ports have the same sim syscall logic, so add some helpers to handle
all the common details.  The arches still have to deal with the unpacking
and packing of the syscall arguments, but the rest of the sim<->callback
glue is now shared.

5b064994f0 sim: msp430: use new common trace print helpers
Replace the "if (TRACE_xxx_P) trace_generic" form with "TRACE_xxx".
The output is the same, but the code is nicer to read.

	declared in the libgloss/msp430 linker scripts.

	range addresses.

7b0278dcad sim: msp430: set initial PC to ELF entry if available
If we want to run a simple ELF, the reset vector isn't set up, so starting
at address 0 doesn't make sense.  Use the ELF's entry point instead.

a3271a3e6c sim: msp430: fix build time warnings
This fix is simple:

msp430-sim.c: In function 'maybe_perform_syscall':
msp430-sim.c:898:10: warning: format '%d' expects argument of type 'int',
                     but argument 5 has type 'long int' [-Wformat]

This one we change to use casts like everyone else does in the code base:

msp430-sim.c: In function 'msp430_step_once':
msp430-sim.c:985:7: warning: passing argument 3 of 'init_disassemble_info'
                    from incompatible pointer type [enabled by default]
