| 17:24 | [c6b3fa301d] part of check-in [d4ccf0f5c6] Make sure the OP_Next and OP_NextIfOpen opcodes are numbered close together for efficiency in switch() statements. OP_Prev and OP_PrevIfOpen too. (check-in: [d4ccf0f5c6] user: drh branch: trunk, size: 6672) | |
|

| ||
| 20:40 | [987ee588ff] part of check-in [5f310c6a22] Automatically generated comments on many VDBE opcodes when in SQLITE_DEBUG mode. Comments derive from the "Synopsis:" field added to each opcode definition in vdbe.c. (check-in: [5f310c6a22] user: drh branch: trunk, size: 6602) | |
