I would think that, regardless of cache size, the *first* access to a line causes a miss.
The PowerPC and relatives have an instruction which force-allocates (if necessary) AND zeroes an entire cache line, so in some ways the "first" access is a Write which succeeds with no miss. _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
