When connecting to the simulator in gdb, we don't want it to exit on
us when we pass down unknown/invalid/help/etc... options. Plumb down
the kind argument so we can handle both gdb & psim interfaces.
Fixes an error reported by Tristan and which can be evidenced by
doing:
% powerpc-elf-gdb
(gdb) target sim --sysroot=var
Invalid option: --sysroot=/var
[...]
sim/ppc/ChangeLog:
* psim.c (psim_options): Fix length of comparison when checking
for --sysroot= option.
This patch improves the error message when an invalid option is
detected, by also printing the option that actually caused the error.
For instance, from GDB:
(gdb) target sim --hello
Invalid option: --hello
Usage:
[...]
We also added the usage after an invalid long-name option (Eg: --hello)
to be in line with what's being done for all other invalid options
being detected.
sim/ppc/ChangeLog:
* psim.c (psim_options): Add option that cause the error
in invalid-option error messages. Print the usage when
detecting an invalid long-name option.
There was a recent change that cuased the "target sim" command
to add a --sysroot option to the argument vector passed down to
the simulator. This caused a failure in the powerpc simulator,
as it did not recognize it. This patch fixes the problem by adding
support for the --sysroot option (it ignores it).
sim/ppc/ChangeLog:
* psim.c (psim_options): Accept and ignore `--sysroot=...'.
sim_resume. Expect target signal numbers from sim_stop_reason.

sim_signal_to_target, not sim_signal_to_host.
* sim-signal.c (sim_signal_to_host): Fix typo.
(sim_signal_to_target): New function.
* interp.c (gdb/signals.h): Include it.
(sim_stop_reason): Use TARGET_SIGNAL_*.
* interf.c: (gdb/signals.h): Include it.

* sim_calls.c (gdb/signals.h): Include it.
(sim_stop_reason): Use TARGET_SIGNAL_*.
* psim.c (cntrl_c_simulation): Use TARGET_SIGNAL_*.
