105 ;; The pipeline is modelled as a fetch unit, and a core with a memory unit,
106 ;; two execution units, where "fetch" models IF and D, "memory" for MEM1
107 ;; and MEM2, and "EXEC" for E, E1, E2, EM, and EA. Writeback and

114 ;; These fetch units are a hack to get GCC to better pack the instructions
115 ;; for the M32Rx processor, which has two execution pipes.
117 ;; In reality there is only one decoder, which can decode either two 16-bit
118 ;; instructions, or a single 32-bit instruction.
