Hi Stuart, Thanks for the reply, but since I'm a little new to qemu, can you please elaborate on how to insert the op_dump_pc function to extract the PC values?

BTW, the approach I took was to add something like gen_op_dump_pc(s->pc) near the top of disas_insn (in translate.c), and have op_dump_pc (in op.c) pass the program counter (held in PARAM1) to a helper (in helper.c) that then prints it out. I expect that's not the best approach, but it worked quite well for my purposes. Cheers, -- Stuart Brady
