;; The HyperSPARC is a dual-issue processor. It is not all that fancy.
;; ??? There are some things not modelled. For example, sethi+or ;; ??? coming right after each other are specifically identified and ;; ??? dual-issued by the processor. Similarly for sethi+ld[reg+lo]. ;; ??? Actually, to be more precise that rule is sort of modelled now.
