* d10v-sim.h (simops): Add flag is_long.
	(State): Add pc_changed.  Instructions which update the PC should
	use the JMP macro which sets this.
	(JMP): New macro.  Sets the PC and the pc_changed flag.

	* gencode.c (write_opcodes): Add is_long field.

	* interp.c (lookup_hash): If we blindly apply a short opcode's mask
	to a long opcode we could get a false match.  Check the opcode size.
	(hash): Add a size field to the hash table.
	(sim_open): Initialize size field in hash table.
	(sim_resume): Change to logic for setting the PC.  Used to increment the
	PC if it had not been changed.  This didn't allow single-instruction loops.
	Now checks the flag State.pc_changed.  Also now stops when ^C is received.
	(dmem_addr): Fix translation of data segments to unified memory.
	(sim_ctrl_c): New function.  When ^C is received, set stop_simulator flag.

	* simops.c: Changed all branch and jump instructions to use new JMP macro.
	(OP_20000000): Corrected trace information to show this is a ldi.l, not
	a ldi.s instruction.

* interp.c (sim_size): Now allocates unified memory for imap segments

	(sim_write): Just call xfer_mem().
	(sim_read): Just call xfer_mem().
	(xfer_mem): New function. Does appropriate memory mapping and copies bytes.
	(dmem_addr): New function. Reads dmap register and translates data
 	addresses to local addresses.
	(pc_addr): New function. Reads imap register and computes local address
	corresponding to contents of the PC.
	(sim_resume): Change to use pc_addr().
	(sim_create_inferior): Change reinitialization code. Also reinitializes
	imap[01] and dmap.
	(sim_fetch_register): Add fake registers 32,33,34 for imap0, imap1, and dmap.

(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.

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.

* run.c (main): Explicitly cast malloc() parameter.

This is needed because for certain builds the size field being given
to malloc() is actually 64bits long, and without a cast or malloc
prototype the resulting value used by malloc() depended on the host
endianness, and how long long paramaters are passed into functions.

* interp.c (ColdReset): Fix boolean test.

Actually compare a boolean result, rather than the bitmasks!

	* interp.c (ColdReset): Provide function indirection to
 	host<->simulated_target transfer routines.
	* interp.c (sim_store_register, sim_fetch_register): Updated to
 	make use of indirected transfer routines.

 	system call support.

e24146ec95 * compile.c (decode): Use "bit" to hold L_3 immediates instead
of holding them in "abs".  Handle ABS8MEM memory references aka
        8-bit area.  Replace ABSMOV references with ABS8MEM.
So we've got a chance of simulating something like btst #0,@40:8 correctly.

* interp.c (Convert): Provide round-to-nearest and round-to-zero
 	support for Sun hosts.
	* Makefile.in (gencode): Ensure the host compiler and libraries
 	used for cross-hosted build.

Allow a DOS hosted version of the simulator to be built. NOTE: The FP
is still not complete, since round-to-nearest and round-to-zero have
not been implemented generically.

* gencode.c, interp.c: Replaced explicit long long references with
 	WORD64HI, WORD64LO, SET64HI and SET64LO macro calls.
	* support.h (SET64LO, SET64HI): Macros added.

This is an intermediate checkin. The work of removing "long long"
usage is not yet finished. These changes are clean, and have been
sitting on my machine for a while (whilst doing other work), and it is
safer for them to be checked in.
