Alex Bennée 453d50ce75 accel/tcg: re-factor plugin_inject_cb so we can assert insn_idx is valid ... Coverity doesn't know enough about how we have arranged our plugin TCG ops to know we will always have incremented insn_idx before injecting the callback. Let us assert it for the benefit of Coverity and protect ourselves from accidentally breaking the assumption and triggering harder to grok errors deeper in the code if we attempt a negative indexed array lookup. However to get to this point we re-factor the code and remove the second hand instruction boundary detection in favour of scanning the full set of ops and using the existing INDEX_op_insn_start to cleanly detect when the instruction has started. As we no longer need the plugin specific list of ops we delete that. My initial benchmarks shows no discernible impact of dropping the plugin specific ops list.
