"m5_dump_stats()" defined as a global fucntion, is "0x0F04" a pseudo instruction in m5? "0x0041" is the interrupt vector? there are no machine code like "0x0F04" in X86 ISA. 2. how to change the function "m5_dump_stats()" in m5, or how to add a new pseudo instruction like m5_dump_stats()? or the machine code like "0x0F04" parsed by which file ? thank you for your patience!
