Changes In Branch failed-optimization Excluding Merge-Ins
This is equivalent to a diff from 6e106acd to 8a90f691
2017-01-09
| ||
18:22 | Fix typo in a comment. No changes to code. (check-in: d38fd229 user: mistachkin tags: trunk) | |
18:20 | Try to move OP_Concat operations outside the inner loop. This turns out to make things very slightly slower, at least in speedtest1.c. (Closed-Leaf check-in: 8a90f691 user: drh tags: failed-optimization) | |
15:44 | Modify the OP_RowData opcode so that when P3!=0 it is allowed to hold an ephemeral copy of the content. This avoids unnecessary memcpy() operations in the xfer-optimization and VACUUM. (check-in: 6e106acd user: drh tags: trunk) | |
13:43 | Add the SQLITE_UINT64_TYPE compile-time option. (check-in: a5fe03bc user: drh tags: trunk) | |
Changes to src/expr.c.
