|22:21||Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7 user: drh tags: trunk)|
|19:18||Change the OP_InitCoroutine instruction to jump over the co-routine implementation. (Closed-Leaf check-in: a522f364 user: drh tags: coroutine-refactor)|
|18:27||Get rid of the OP_Undef and OP_IsUndef opcodes in favor of higher-level OP_InitCoroutine and OP_EndCoroutine. (check-in: 1ec0e9dd user: drh tags: coroutine-refactor)|
|13:20||Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. (check-in: 6fb74485 user: drh tags: coroutine-refactor)|
