1997-12-01Rework sim/common/sim-alu.h to differentiate between direcctAndrew Cagney2-11/+40
subtraction (involves borrow) and negated addition (involves carry). Update d30v so that it uses this method. Add more tests.

1997-11-26Move MDMX instructions which are public knowledge from vr5400.igenAndrew Cagney4-441/+1313

1997-11-24SanitizationAndrew Cagney2-1/+5
1997-11-23Change MIPS simulator so that it uses the (software) module sim_fpuAndrew Cagney1-1/+6
for floating point operations. Eliminates all dependencies the simulator had on the hosts FP implemantation. Add sim_fpu_{inv,abs,neg} functions to sim_fpu.[hc]
1997-11-22Clarify meaning of sim_signalled's SIGRC argument. Document that thisAndrew Cagney7-14/+35
isn't possible in sim-reason.c and just return the target SIGRC instead. For simulators that rely on sim-reason.c, replace SIG* with SIM_SIG*. Hack nrun.c so that when it is executed (ARGV[0]) as `step' instead of `run' it single steps the simulator. Allows testing of single step without full GDB.
1997-11-20Pacify GCC - SIM_SIGNONE missing in enum, xmalloc/free VS ZALLOC/zfree.Andrew Cagney2-0/+8
1997-11-20o Add SIM_SIGFPE to sim-signalsAndrew Cagney5-18/+25
o Start SIM_SIG* at 64 so that the use of host signal numbers can be detected and reported. o Update MIPS simulator to use sim-signal.

(engine_signal): Update prototype. * cgen-utils.c: Don't include <signal.h>. (sim_signal_to_host): Delete, lives in sim-signal.c now. (engine_signal): Update.
1997-11-19 * mem-ops.h: Rename SIM_SIG{ACCESS,ALIGN} to SIM_SIG{SEGV,BUS}.Doug Evans1-32/+32
* sim-if.c (sim_open): Call sim_config. (sim_stop_reason): Update call to sim_signal_to_host.
1997-11-19 * sim-utils.c (sim_state_alloc): Call SIM_STATE_ALLOC if defined.Doug Evans1-0/+8
