* simops.c (OP_4201): For "rac", sign extend 56 bit value before
it is shifted.
* d10v_sim.h (MAX32, MIN32, MASK32, MASK40): Re-define using
SIGNED64 macro.
* interp.c (sim_size): Now allocates unified memory for imap segments
0,1,2, and 127. Initializes imap0 and imap1 to 0x1000. Initializes dmap to 0.
(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.
