8517f62b16 Ref gdb/11763 - can't stop a running simulator:
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).

a77aa7ec4b * configure: Re-generate.

        the search path.

        SIM_WARNING): Drop, requiring the simulator specific Makefile.in
        to explicitly incorporate these.

        * aclocal.m4 (--enable-sim-alignment); New option. Strongly
        specify the alignment restrictions of the target architecture -
        without this option all alignment restrictions are accomodated.

        assertion statements.
        (--enable-sim-float): New option. Strongly specify the target's
        floating point support.
        (--enable-sim-hardware): New option.  Specify the hardware devices
        included in the simulation.
        (--enable-sim-packages): New option.  Specify the hardware
        packages included in the simulation.
        (--enable-sim-regparm): New option.  Specify that parameters be
        passed in registers instead of on the stack.
        (--enable-sim-reserved-bits): New option. Specify that reserved
        bits within an instruction are are correctly set.
        (--enable-sim-smp): New option. Specify the level of SMP support
        to be included in the simulator.
        (--enable-sim-stdcall): New option.  Specify an alternative
        function call convention.
        (--enable-sim-xor-endian): New option.  Configure xor-endian
        support used by some targets to implement bi-endian support.

f009978996 * simops.c (OP_500): Mask off low bit in displacement
for sld.w.

0a89af6efd * simops.c (trace_input): Remove all references to SEXT7.
(OP_300, OP_400, OP_500, OP_380, OP_480, OP_501): Displacement
        is zero extended for sst/sld instructions.
        * v850_sim.h (SEX7): Delete.  It's no longer needed (and it
        was incorrect anyway).
So we properly simulate sst/sld instructions.

968519095a * Makefile.in: Get rid of srcroot. Set all INSTALL macros via
autoconf.
	* gencode.c (write_opcodes):  Pad operands field to account for
	MSVC braindamage.
	* simops.c:  Include errno.h.  Exclude SYS_chown, since MSVC
	doesn't support it.  (Why is this here in the first place?!?)
	* v850_sim.h:  Get rid of 64 bit defs.  Also, get rid of #elif's.
	Change number of operands in struct simops from 9 to 6.  Define
	SIGTRAP and SIGQUIT for MSVC.

254ef34062 * interp.c (MEM_SIZE): It's now bytes, not a power of 2.
* (map):  Add support for external mem in the 1->2 meg range.
	Also, abort() when memory access is way out of bounds.  (Better to
	die than to give wrong result.  (This will be fixed later.))
	* (sim_size):  MEM_SIZE is now bytes, not shift factor.
