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 Cagney2-0/+13
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.
