* sim-options.c (sim_parse_args): Mark argv array const.
* sim-options.h (sim_parse_args): Likewise.
|
|
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.
|
|
A bunch of places open code the countargv implementation, or outright
duplicate it (as count_argc). Replace all of those w/countargv.
|
|
The --enable-sim-hostendian flag was purely so people had an escape route
for when cross-compiling. This is because historically, AC_C_BIGENDIAN
did not work in those cases. That was fixed a while ago though, so we can
require that macro everywhere now and simplify a good bit of code.
|
|
Rather than re-invent endian defines, as well as maintain our own list
of OS & arch-specific includes, punt all that logic in favor of the bfd
ones already set up and maintained elsewhere. We already rely on the
bfd library, so leveraging the endian aspect should be fine.

to common sim_{fetch,store}_register
|
|
We can use the sim state everywhere now to get these values on the fly.
|
|
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 makes the common sim-cpu logic work.
|
|
A lot of cpu state is stored in global variables, as is memory handling.
The sim_size support needs unwinding at some point. But at least this
is an improvement on the status quo.
|
|
Mostly converting old style prototypes. Also include a few missing
headers, and add static/casts where appropriate.
|
|
It is rare for people to want to modify the cmd arg. In general, they
really shouldn't be, but a few still do. For those who misbehave, dupe
the string locally so they can bang on it.
|
|
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.
|
|
Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:
sigsave = signal (SIGINT, interrupt);
However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.

Fix compile warnings for sh built on 64-bit hosts.
|
|
For the ports that don't use the common/ subdir, we need to add stub funcs
to them to avoid build failures with gdb and command completion. These do
not implement the actual completion functionality ... any port that wants
that can either convert to the common/ subdir, or fill out the function on
their own time.
