- Some architectural changes: a) We specialize opcodes according to op_type fields. Each opcode has to be marked with which op_type's it uses. b) We support different execution methods. Function handlers, switch() and goto dispatching. goto seems to be the fastest but it really depends on the compiler and how well it optimizes. I suggest playing around with optimization flags. - Warning: Things might break so keep us posted on how things are going. (Dmitry, Andi)
