|

* 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.
