Martin Hunt 849c575f97 Fri Nov 8 16:19:55 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* 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.

	State variable.

Martin Hunt c422ecc7a4 Tue Oct 29 12:13:52 1996 Martin M. Hunt <hunt@pizza.cygnus.com>
* 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.
