instruction tracing #14

Open s0i37 opened 4 years ago

s0i37 commented 4 years ago

Hello. I'm trying to grab execution trace of each instruction with full registers state. But it seems all APIs support only basic block translationg/execution events. Do I undrestand right that it is impossible to handle exection of each instruction? Thank you.

Hello,

indeed, API are focus on block translation, mainly for efficiency reasons. If you want to do instruction level instrumentation, you must do it by hand (see after_gen_opc here: https://github.com/atos-tools/qemu/blob/next/master/tcg/plugins/dyncount.c).
