| 21:11 | • Edit [bad4d7a0d93f4d8f|bad4d7a0]: Mark "Closed". (artifact: ca328fec user: drh) | |
| 21:11 | Attempt to parse the NULLS LAST clause more efficiently. A few cycles were saved, but at the expense of more code. And there is a bug was introduced somewhere. Not worth continuing down this line. (Closed-Leaf check-in: 12d2cf88 user: drh tags: dead-end) | |

| 17:00 | Additional simplifications of the WHERE loop code generator logic for NULLS LAST. (check-in: 1383680d user: drh tags: nulls-last) | |
| 16:12 | Simplification of the WHERE loop code generator for NULLS LAST saves a few CPU cycles and about a hundred bytes of code space. (check-in: e3ed2f49 user: drh tags: nulls-last) | |
| 13:32 | Invert the meaning of the regBignull flag so that it is 1 when doing the normal scan and 1 when scanning nulls. This enables the re-do jump at the bottom of the loop to be coded with a single OP_IfNotZero opcode, rather than a sequence of OP_If, OP_Integer, OP_Goto. (check-in: bf875e1a user: drh tags: nulls-last) | |
| 13:08 | Extra VDBE comments in the NULLS LAST logic provide landmarks to help understand the EXPLAIN output. (check-in: 649b08ea user: drh tags: nulls-last) | |
