Hi, gem5-user, I want to collect the instruction size in X86. I printout the "instSize" in src/cpu/o3/fetch_impl.hh. It shows that all the instruction size is 8, which means all the instruction is 64 bits. From my understanding, the instruction size should be variable in X86 ISA, So could anyone tell me why all the instruction size is same and it's 8? Thanks a lot.
In addition, does the instruction size matter with the X86 mode. I mean if I choose another mode, such as "compatibly mode" by changing the configure in process.cc, should the instruction size change ? Actually, I changed the mode from "sixtyfourbitmode" to"compatibility mode", but the instruction size is still 8. Any hint is appreciable. Thank you for your time. Xiangyang
