| 14:28 | If a subquery is used to drive an index, this change avoids making an extra copy of the result of that subquery. But, such situations are probably sufficiently unusual that the added complexity of this enhancement is not worth the performance gain. So I'm going to park this check-in on a branch. If we later find a use case to justify it, we can merge it to trunk then. This is the "further change" that was promised by the prior check-in comment. (Leaf check-in: 4488cb883e user: drh tags: copy-optimization) | |

Further changes to try to optimize the new OP_Copy opcode back into either OP_SCopy or OP_Move will be attempted separately. A test case will be in TH3.
