| 18:53 | Omit the SQLITE_STOREP2 and SQLITE_KEEPNULL options from the comparison opcodes, allowing them to run faster. This required refactoring the vector comparison logic, which in turn required changing OP_ElseNotEq into OP_ElseEq. (check-in: 380b46054b user: drh tags: compare-opcode-opt) | |
| 14:40 | Add the OP_ZeroOrNull opcode and use it to compute boolean values for scalar comparisons, rather than the SQLITE_STOREP2 parameter to the comparison opcode. (check-in: 93781b6f10 user: drh tags: compare-opcode-opt) | |
| 13:47 | The comparison opcodes (ex: OP_Eq) now set the iCompare flag so that the result of comparison can be used by subsequent OP_Jump or OP_ElseNotEq opcodes. (check-in: bd00df8f07 user: drh tags: compare-opcode-opt) | |

| 20:45 | Performance improvement in the comparison opcodes by rewriting an array lookup using pointer arithmetic. This makes gcc 5.4.0 builds with -Os both faster and smaller. Though I suspect that in newer compilers with better optimizers in will probably make no difference at all in the generated machine code. Later: Even though the new code is perfectly valid, and generates correct machine code that is both smaller and faster, UBSAN complains about it in OSSFuzz. So we will take it out. So here was have an example of OSSFuzz coercing a widely used application to become bigger and slower. (Leaf check-in: 4a8805d9a6 user: drh tags: gcc-opt) | |
