Gary Benson 6aefca7e49 Shadow SIM's debug_printf function
GDB and SIM both have functions called "debug_printf", which conflicts
at link time.  This commit shadows SIM's debug_printf with a macro so
that SIM's symbol ends up being called "sim_debug_printf".

sim/common/ChangeLog:

	* sim-trace.h (debug_printf): New define.

Hans-Peter Nilsson 9e3042ec07 Fix m32r-elf sim, default hardware to off.
The situation here is similar to that of the other nearby (previous)
sims fixed; it fails at the dv_sockser_install declaration in
sim/m32r/tconfig.in.  But, as opposed to e.g. frv, this *does* have a
definition of UART_INCHAR_ADDR et al.  It's somewhat tempting to keep
sim-hardware enabled here but, I'm disabling it for the same reasons
as for frv.  Unsurprisingly (as m32r seems to be the template), the
same confusing lines are in sim/m32r/Makefile.in as in
sim/frv/Makefile.in at that time, deleted in 73e76d20.  Again, commit
73e76d20 (for m32r as well as for frv) attempted to move the
non-existing dv-sockser.o use to $(m32r_extra_objs) but missed that
AC_SUBST would only affect @m32r_extra_objs@ and not
$(m32r_extra_objs) per se so nothing happened.  As for frv, I'm
removing the $(m32r_extra_objs) too, to avoid confusion.  Make
check-sim for m32r-elf shows no regressions (5 failures; 100 expected
passes) compared to bf3d9781ec (before the recent config.in regen,
after sim-hardware mostly-enabled) and eed23bb4a1 (before the
sim-hardware mostly-enabled; 2013-03-23).

sim/m32r:
	* configure.ac: Default simulator hardware to off again.  Remove
	dead m32r_extra_objs substitution.
	* configure: Regenerate.
	* Makefile.in: Remove unused frv_extra_objs.

Hans-Peter Nilsson c4892a6b37 Fix sh64-elf sim, default hardware to off.
See nearby (previous) commit for the iq2000 sim; this similarly fails
at the dv_sockser_install declaration in sim/sh64/tconfig.in.  I'm
disabling simulator hardware to be consistent with the state before
94c63d78f (2013-03-23) and with the actions for the frv sim and the
iq2000 sim.  Make check-sim for sh64-elf shows no regressions (25
failures; 357 expected passes) compared to bf3d9781ec (before the
recent config.in regen, after sim-hardware mostly-enabled) and
eed23bb4a1 (before the sim-hardware mostly-enabled; 2013-03-23).

sim/sh64:
	* configure.ac: Default simulator hardware to off again
	without emitting errors when off or dv-sockser.o unavailable.
	* configure: Regenerate.

Hans-Peter Nilsson 3df3af7c3f Fix iq2000-elf sim, default hardware to off.
See nearby (previous) commit for the frv sim; this similarly fails at
the dv_sockser_install declaration in sim/iq2000/tconfig.in.  There's
no HAVE_DV_SOCKSER conditionals here and no other dv-sockser.o
artefacts so maybe there is no further fallout, but I'm going to
disable sim-hardware just be consistent with the state before
94c63d78f (2013-03-23) and with the actions for the frv sim.  Make
check-sim for iq2000-elf shows no failures but that's in no small part
because it has no test-suite.

sim/iq2000:
	* configure.ac: Default simulator hardware to off again
	without emitting errors when off or dv-sockser.o unavailable.
	* configure: Regenerate.

Hans-Peter Nilsson 105dd264de Fix frv-elf sim, default hardware to off.
At 2974be626, frv-elf fails at the dv_sockser_install declaration in
sim/frv/tconfig.in.  But, with the trivial #include's added (see other
sims tconfig.in, like cris or mn10300), it *still* fails building
sim/frv/devices.c because of a missing UART_INCHAR_ADDR.  I have no
insight into what'd be a valid value, except that there's a definition
in m32r, which was probably used as a template with frv not finished.
Simulated hardware should not have been be enabled, and was indeed not
enabled by default before 94c63d78f (2013-03-23), where it seems to
have been enabled for no simulator-specific reason.  Except
dv-sockser.o wasn't enabled even then: sim/frv/config.in wasn't
regenerated, so HAVE_DV_SOCKSER was never defined.  Maybe people were
fooled by this in sim/frv/Makefile.in at that time (these two lines
were later deleted, in 73e76d20):
CONFIG_DEVICES = dv-sockser.o
CONFIG_DEVICES =
(As it seems people have missed it before: the second line overrides
the first...)  I'm guessing these lines were part of the
never-completed hardware-support.  Commit 73e76d20 attempted to move
the imagined dv-sockser.o from $(CONFIG_DEVICES) to $(frv_extra_objs)
but missed that AC_SUBST would only affect @frv_extra_objs@ (not
$(frv_extra_objs) per se) so nothing happened regarding sockser:
dv-sockser.o was not compiled and HAVE_DV_SOCKSER was not defined.
I'm removing the $(frv_extra_objs) too, to avoid confusion.  The best
action seems to be disabling all hardware support by default again
until a specific sim maintainer finishes the work.
Make check-sim for frv-elf shows no failures after this.

sim/frv:
	* configure.ac: Default simulator hardware to off again.  Remove
	dead frv_extra_objs substitution.
	* configure: Regenerate.
	* Makefile.in: Remove unused frv_extra_objs.

Kevin Buettner fa0dd93eca Revise signal mapping function in GDB interface for RX sim.
sim/rx/gdb-if.c had a function named `rx_signal_to_host'.  This
	function mapped signal numbers used by the BSP to host signal
	numbers which, at one time a while back, were used by GDB
	as target signal numbers.  This change updates the signal
	numbers returned to be those names prefixed with "GDB_SIGNAL_"
	as defined in include/gdb/signals.h.

	It also changes the name of the function somewhat to better
	match what the function currently does.  I noticed that this
	function is not static - and there's no reason for it not
	to be - so I made it static too.

	* gdb-if.c (rx_signal_to_host):  Rename to
	`rx_signal_to_gdb_signal'.  Make static.  Update all callers
	to use new name.  Use signal names from include/gdb/signals.h.

Mike Frysinger ef3e8cf7d1 sim: delete duplicate SIGINT handling
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.

Aaro Koskinen 0d8a6ab7d3 sim: ppc: drop $(LIBS) from psim dependency
When cross-compiling GDB for PPC, there's a prerequisite "-lz" for psim
that results in a build failure. With such prerequisite, GNU Make will
try to search the library from build machine's /usr/lib which is wrong.
On 64-bit Linux build machines the compilation will fail because of this.

Mike Frysinger 48a9389710 sim: bfin: note missing parallel handling of SEARCH
The SEARCH insn is an oddball when it comes to parallel usage.  It places a
big limit on what other insns it can run in parallel with, but we don't
currently track the amount of state needed to verify this (since no other insn
really requires this).  Add a note for now in case we get around to it.

Mike Frysinger 03dccef1ab sim: bfin: handle invalid HLs encoding in dsp shift insns
For many of the 32bit dsp shift related insns, we were just ignoring the HLs
field.  The hardware does not though and will reject the insn if it's set
incorrectly.  Update the sim to match.
