21:54
Continuing cleanup of memory register memory allocation handling. (check-in: 2598aedc user: drh tags: micro-optimizations)
20:05
Make sure registers are cleared properly prior to being used to store the result of an OP_Column operator. (check-in: 78fb8838 user: drh tags: micro-optimizations)
18:22
Simplification of the OP_Column logic for the case of rows with overflow. (check-in: f7367803 user: drh tags: micro-optimizations)
14:55
Remove an unused parameter from sqlite3VdbeIdxRowid(). This is cosmetic only as the C-compiler optimizers were already omitting this parameter on amalgamation builds. (check-in: a10a6bba user: drh tags: micro-optimizations)
14:37
Reduce the number of arguments to RecordCompare functions from 4 to 3, resulting in a small performance increase. (check-in: 8239c35a user: drh tags: micro-optimizations)
14:16
Reorder the elements of the Mem object for a small size reduction and performance improvement. Moved into a branch because MSVC is unable to handle named structure initializer on nullMem. (check-in: 0be3019e user: drh tags: micro-optimizations)
