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.
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.
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.
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.
