...
* 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.

(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.
(sim_store_register): Add fake registers 32,33,34 for imap0, imap1, and dmap.
* simops.c (MEMPTR): Redefine to use dmem_addr().
(OP_5F00): Replace references to STate.imem with dmem_addr().
* d10v-sim.h (State): Remove mem_min and mem_max. Add umem[128].
(RB,SW,RW,SLW,RLW): Redefine to use dmem_addr().
(IMAP0,IMAP1,DMAP,SET_IMAP,SET_IMAP1,SET_DMAP): Define.
