95469cebdd Replace global IPC with function argument cia or current instruction
address.
Pass cia into calls to sim_engine_stop so that breakpoints et.al. work.

549bf95051 Fix computation of sim_events_time when sim_events_slip is loosing it. 1997-11-06 14:14:33 +00:00

7ce8b9178c IGEN likes to cache the current instruction address (CIA). Change the
MIPS simulator so that correctly writes the value of CIA back int PC
(the global previously used) when the simulation halts.
Fix implementation of DELAY_SLOT and NULLIFY_NEXT_INSTRUCTION macros.

63be8febf7 Rewrite the MIPS simulator's memory model so that it uses the generic
common/sim-core.

Add support for 3, 5, 6, 7 byte transfers to sim core.

22de994d0e Delete -l and -n options, didn't do anything.
Rename option trace to dinero-trace & dinero-file - -t clashed with
common options.

525d929e49 Rewrite sim_monitor (implements read, write, open, et.al. system
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write.  This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
