I don't follow what you mean. AFAIK INDEX_op_insn_start does not change the
guest eflags.
It sets cc_op, which affects how eflags is computed.
I see tcg_gen_insn_start() gets dc->cc_op as a second argument, but I really
don't see where it gets modified (I'm looking at tcg_gen_code() on the
INDEX_op_insn_start case).
The ultimate change is in restore_state_to_opc, via cpu_restore_state.
