Hey all,

This patch solves the problem that the sparc instruction simulator (SIS) would hang after a few minutes of simulation time (time depending on speed of host pc), because of the use of 32 bit counters internally.

This patch doesn't change anything to simulator behaviour, except that it allows for longer simulation times.

There may be a problem with the use of 64 bit integers, but that was also there before this patch.

Thanks,

Tiemen Schut
