Task Summary:
Bytecode overview in Ruby 1.9 |
Original Comment:
* Is the length of an instruction of YARV fixed or varying?
* What's the minimum length of an instruction? (is there a 1-byte nop?)
* How long does a trace instruction take?
* If we want to replace an instruction longer than the trace
instruction, we would have to add extra NOPs.
* If we want to replace an instruction shorter than the trace
instruction, we would use a jump instruction -- problem becomes:
how long does a jump instruction takes?
