The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.
On x86-64 Fedora 32, the sim was failing to build.
sim_events_schedule was passing a 'dummy' argument to
sim_events_schedule_vtracef, which caused an error because the format
parameter was NULL. However, removing this dummy argument caused an
error because too few arguments were being passed -- catch 22.
This patch fixes the build problem by using sim_events_schedule_tracef
instead.

* sim-events.c (sim_events_schedule): Use
sim_events_schedule_tracef.
Few arches implement STATE_WATCHPOINTS()->pc while all of them implement
sim_pc_get. Lets switch the sim-watch core for monitoring pc events to
the sim_pc_get API so this module works for all ports, and then we can
delete this old back channel of snooping in the port's cpu state -- the
code needs the pointer to the pc storage so that it can read out bytes
and compare them to the watchrange.
This also fixes the logic on multi-cpu sims by removing the limitation
of only being able to watch CPU0's state.
My change 1ac72f0659d64d6a14da862242db0d841d2878d0 ("sim: convert to
bfd_endian") subtly broke the watchpoint module on little endian host
systems. The old code used 0 to mean "whatever the host endian is",
and while that was changed to use BFD_ENDIAN_UNKNOWN, this caller was
missed. Since its API used an int instead of an enum, the coercion
from 0 to the BFD endian enum was silently missed, and 0 happens to
be BFD_ENDIAN_BIG.
Instead of restoring the old logic by passing in BFD_ENDIAN_UNKNOWN,
we know the right host endian at compile time, so use that directly.
Since we require C11 now, we can assume many headers exist, and
clean up all of the conditional includes. It's not like any of
this code actually accounted for the headers not existing, just
whether we could include them.
The strings.h cleanup is a little nuanced: it isn't in C11, but
every use of it in the codebase will include strings.h only if
string.h doesn't exist. Since we now assume the C11 string.h
exists, we'll never include strings.h, so we can delete it.
This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...
gdb/ChangeLog
Update copyright year range in copyright header of 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.
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.
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.
This helper macro has largely the same behavior as libiberty's lbasename.
There is a slight nuance related to colons, but it's not clear what the
point of that is, and the code implies that it just wants the basename.
First we convert the ETRACE_P to STRACE_EVENTS_P. This means we move from
using the sim_events.trace storage to the common sim_state_base.trace_data
array. With that deleted, the common trace init code can be simplified so
the sim state works the same as the sim cpu.
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.
* sim-events.c (sim_events_remain_time): New function returning
the time that remains before the event is raised.
* hw-events.c (hw_event_remain_time): Likewise.
* sim-events.h (sim_events_remain_time): Declare.
* hw-events.h (hw_event_remain_time): Declare.
1998-12-24 Frank Ch. Eigler <fche@cygnus.com>
* dv-sockser.c (DEFAULT_TIMEOUT): Increase to 1 ms.
* nrun.c (main): Remain in simulation loop for traps and
exceptions when in operating environment mode.
(ui_loop_hook): New stub hook for standalone use.
* sim-events.c (sim_events_process): Call ui_loop_hook
periodically on CYGWIN host.
* sim-reason.c (sim_stop_reason): Return host signal numbers
to gdb on sim_stopped and sim_signalled cases.
* sim-engine.c (sim_engine_halt): Call SIM_CPU_EXCEPTION_SUSPEND
hook just before longjmp.
* sim-resume.c (sim_resume): Call SIM_CPU_EXCEPTION_RESUME
hook just before sim_engine_run.
* sim-n-core.h (sim_core_trace_M): Allay const warning.
* sim-trace.h (trace_generic): Ditto.
* sim-trace.c (trace_generic): Ditto.
o Provide poll_quit callback to simulators
so that they can poll for SIGINT on
clueless OS's.
o Add sim_stop to simulators so that clients
can request a halt (eg gdbtk's STOP button)
Works for PPC!
o Re-arange remote-sim.c so that the
hard work is moved from gdbsim_resume()
to gdbsim_wait() (where it should be).
