@ -64,6 +64,12 @@ Result: Regressed from 3200 to 3600. Not sure why.

Plan: OP_GETFIELD hits the constants a lot. I thought caching it and not dereferencing the chunk and block constantly might help.

## Splitting up the opcode match
|
||||
|
||||
Result: No change, 3200 to 3200. Maybe Rust was already optimizing this into an optimal jump table?
|
||||
|
||||
Plan: Maybe if the hot inner opcodes, OP_GETFIELD, OP_MUL, and OP_SETFIELD get their own match statement at the top of the function, the step function can exit sooner.
