However then that got me to thinking, it seems that we can call a portion of the TCG system to disassemble a single instruction. TranslationBlock tb; tb.pc = env->pc; gen_intermediate_code(cs, &tb, /* max isn */ 1); int ilen = tb.size; printf( "PC: %08x sz:%08x\n", env->pc, tb, ilen ) ; I am very new to TCG, so it does seem there is a lot of code in the translator_loop that appears to be interacting with the CPU model/state. Should I be worried about this, or is this a safe function to call outside of the translator core proper? (if everyone is too busy I can dig by myself but I think its going to take some time) Cheers, Luc
