|21:40||Modify wordcount so that timer information appears on standard error instead of standard output. Rename the run-wordcount.bash script to run-wordcount.sh and simplify it so that it stands a better chance of running on non-GNU systems. (check-in: 586c11ed user: drh tags: trunk)|
|21:23||Do not reuse factored constants that might have had their encodings changed. (check-in: 487f2036 user: drh tags: trunk)|
|20:48||Fix the code generator to honor turning off constant expression factoring. (check-in: 88262266 user: drh tags: trunk)|
|19:27||Add the --timer option to the wordcount test program. (check-in: a89fdf87 user: drh tags: trunk)|
|19:05||Remove a test from sqlite3VdbeMemFromBtree() which was unnecessary, and after the recent OP_Column refactoring, unreachable. (check-in: 23667f3b user: drh tags: trunk)|
|17:24||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: d4ccf0f5 user: drh tags: trunk)|
|16:08||When one or more arguments to a function are constants, try to factor out just those arguments into initialization code. (check-in: 50d350ab user: drh tags: trunk)|
|14:44||Remove the obsolete TK_CONST_FUNC token type. (check-in: 9b4217f0 user: drh tags: trunk)|
|14:33||Add the ability to factor constant functions out of inner loops. But do not factor out non-constant functions, like random(). (check-in: 1b0f779e user: drh tags: trunk)|
|04:18||Another improvement to OP_Function and an improvement to OP_Move. (check-in: 70b056fb user: drh tags: trunk)|
|03:43||A simple change to the OP_Function opcode improves overall performance by about 0.5%. (check-in: b890eefd user: drh tags: trunk)|
|03:12||Performance optimization to the OP_Next and OP_Prev opcodes. (check-in: ecaac28a user: drh tags: trunk)|
