2013-11-15
20:06
Add ALWAYS and NEVER macros to currently unreachable but important branches in sqlite3ExprCompare(). Closed-Leaf check-in: cee835fe user: drh tags: expr-codegen-enhancement
19:00
Merge the operator comment fixes from trunk. check-in: 9f14f55c user: drh tags: expr-codegen-enhancement
18:58
Fix comments on the OP_Divide and OP_Remainder operators, especially the "Synopsis:" comment, so that they agree with the actual implementation. check-in: cc17f1f0 user: drh tags: trunk
18:15
Changes to make the new constant expression factoring logic more general and more testable. check-in: d10fb49a user: drh tags: expr-codegen-enhancement
16:48
Add test cases for INSERT INTO ... DEFAULT VALUES on tables with numeric constants in CHECK constraints. check-in: 79ec485b user: drh tags: expr-codegen-enhancement
15:52
Improvements to the Expr comparison routine to make it more general. Improvements to unary-minus code generation so that it can make use of a global constant register with a zero value. check-in: 835be656 user: drh tags: expr-codegen-enhancement
12:41
Simplify the range scan code generate while also avoiding an unnecessary OP_Affinity opcode. check-in: 372686bf user: drh tags: expr-codegen-enhancement

Merge EXPLAIN fixes from trunk. check-in: cd579727 user: drh tags: expr-codegen-enhancement
03:21
Fix a typo in the "synopsis" for the OP_Lt opcode that causes an incorrect comment to be added to EXPLAIN output. check-in: d99a30a2 user: drh tags: trunk
01:10
Rework the logic that factors constant expressions out of inner loops, making it both simpler and faster. check-in: 8dc5c76c user: drh tags: expr-codegen-enhancement
