No, I hadn't seen the s/pred/pret/ typo. Your code does:
if (pred->op != OP_BAND) pred->op = true; else pred->op OP_EQ;
Realy we should probably trigger a static checker warning any time someone does a compare operations as part of a "x = comparison ?: bar; Years ago, someone asked me to do that with regards to error codes like:
return ret < 0 ?: -EINVAL;
but I don't remember the results.
