There is surprisingly little about the proper feeding of advanced hardware in that code, two or three constants in cost calculations of which one or two are hardware-dependent.
It is still possible that a later pass arranges jump targets to avoid false sharing of their entries (addresses) in prediction mechanisms and such.
Just look at the assembly output of significantly sized switch statements (with good random values): it's scary :)
Obvsiously engaging in pleasing as much as it can speculative/BTB hardware (to the cost of memory tables!)
