I followed your advice and fixed it the proper way. The attached patch will change
sim-config.[ch].
I have a question about the sim... check out this output:
=========================================================================
run <instructions> [<hush>] - execute <instruction> instructions, no reg dump
if hush
sim) run 4000000000 hush
(sim) r
00002010: : 15000000 l.nop 0 (executed) [cycle 2147483650, #2147483648]
(sim) run 4000000000 hush
(sim) r
0000200c: : 00000000 l.j 0x0 (executed) [cycle 4294967297, #4294967295]
==========================================================================
When I do 'run 4000000000 hush', shouldn't the cycle count be almost double
the value shown? I told the sim to execute 4 billion instructions, and yet the
cycle count is at 2.1 billion.
