but if you hand edit cpu/cpu.h, and change BxICacheEntries, you can try different sizes. I'll make this more flexible with configure. For now, use "--enable-icache" with no parameters. - Modified fetchdecode.cc/fetchdecode64.cc just enough so that instructions which encode a direct address now use a memory resolution function which just sticks the immediate address into rm_addr. With cached instructions we need this.
