Has anyone ever identified any ISA issues that are specific for code like this? I have always assumed that a fast branching RISC would be ideal, but I don't know of this is a correct assumption. (I am not asking for a repeat of RISC arguments: any instruction, to be considered, has to show at least a 1% speedup on an actual complete program to be considered for special support.)
