Hi


when laurent imported the old winuae cpu core into Hatari some years 
ago, he added his own code to compute cycles based on whether 
instruction was in cache or not :

CpuInstruction.iCacheMisses++

but this is not part of recent winuae by Toni.

I could add something similar, but this would need to be improved 
anyway, because this code only counted instruction cache misses, but not 
data cache misses.
