Thanks, Mike. I will also have to modify all the accesses to the structure in the MOESI_CMP_NUCA-L2cache.sm, right?

I would probably just add another "hack" variable to SLICC.  Thus you
could do something like:

CacheMemory NUCAcacheMemory, template_hack="<L2Cache_Entry>",
constructor_hack='L2_CACHE_NUM_SETS_BITS,L2_CACHE_ASSOC,MachineType_L2Cache,int_to_string(i)',
abstract_chip_ptr="true", my_new_hack="yes";

Then in $GEMS/slicc/symbols/SymbolTable.C where the Chip.C code is
generated, just check for the existence of your new variable pair by
doing:

if (var->existPair("my_new_hack")) {

// MY SPECIAL CODE
}
