Add a rotate/mask/shift unit and use it in execute1
This adds a new entity 'rotator' which contains combinatorial logic for rotating and masking 64-bit values. It implements the operations of the rlwinm, rlwnm, rlwimi, rldicl, rldicr, rldic, rldimi, rldcl, rldcr, sld, slw, srd, srw, srad, sradi, sraw and srawi instructions. It consists of a 3-stage 64-bit rotator using 4:1 multiplexors at each stage, two mask generators, output logic and control logic. The insn_type_t values used for these instructions have been reduced to just 5: OP_RLC, OP_RLCL and OP_RLCR for the rotate and mask instructions (clear both left and right, clear left, clear right variants), OP_SHL for left shifts, and OP_SHR for right shifts. The control signals for the rotator are derived from the opcode and from the is_32bit and is_signed fields of the decode_rom_t. The rotator is instantiated as an entity in execute1 so that we can be sure we only have one of it. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>pull/78/head
