fafce69ab1 Add ABFD argument to sim_create_inferior. Document.
Add file sim-hload.c - generic load for hardware only simulators.
Review each simulators sim_open, sim_load, sim_create_inferior so that
they more closely match required behavour.

247fccdeb5 Add ABFD argument to sim_open call. Pass through to sim_config so
that image properties such as endianness can be checked.

More strongly document the expected behavour of each of the sim_*
interfaces.

Add default endian argument to simulator config macro
SIM_AC_OPTION_ENDIAN.  Use in sim_config.

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).

9909e232c0 * interp.c (hash): Make this an inline function
when compiling with GCC.  Simplify.
        * simpos.c: Explicitly include "sys/syscall.h".  Remove
        some #if 0'd code.  Enable more emulated syscalls.
Checking in more stuff.

d81352b8b8 * interp.c: OP should be an array of 32bit operands!
(v850_callback): Declare.
        (do_format_5): Fix extraction of OP[0].
        (sim_size): Remove debugging printf.
        (sim_set_callbacks): Do something useful.
        (sim_stop_reason): Gross hacks to get c-torture running.
        * simops.c: Simplify code for computing targets of bCC
        insns.   Invert 's' bit if 'ov' bit is set for some
        instructions.  Fix 'cy' bit handling for numerous
        instructions.  Make the simulator stop when a halt
        instruction is encountered.  Very crude support for
        emulated syscalls (trap 0).
        * v850_sim.h: Include "callback.h" and declare
        v850_callback.  Items in the operand array are 32bits.
Fixes & syscall stuff.

* interp.c (do_format_8): Get operands correctly and
        call the target function.
        * simops.c: Rough cut at "clr1", "not1", "set1", and "tst1".

28647e4c0c * v850_sim.h: The V850 doesn't have split I&D spaces. Change
accordingly.  Remove many unused definitions.
        * interp.c: The V850 doesn't have split I&D spaces.  Change
        accordingly.
        (get_longlong, get_longword, get_word): Deleted.
        (write_longlong, write_longword, write_word): Deleted.

0ef0eba580 * interp.c (hash): Update to be more accurate.
(lookup_hash): Call hash rather than computing the hash
        code here.
        (do_format_1_2): Handle format 1 and format 2 instructions.
        Get operands correctly and call the target function.
        (do_format_6): Get operands correctly and call the target
        function.
        (do_formats_9_10): Rough cut so shift ops will work.
        (sim_resume): Tweak to deal with format 1 and format 2
        handling in a single funtion.  Don't update the PC
        for format 3 insns.  Fix typos.
        * simops.c: Slightly reorganize.  Add condition code handling
        to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
        and "not" instructions.
        * v850_sim.h (reg_t): Registers are 32bits.
        (_state): The V850 has 32 general registers.  Add a 32bit
        psw and pc register too.  Add accessor macros
Fixing lots of stuff.  Starting to add condition code support.  Basically
check pointing the work to date.
