This implements the cfuged, pdepd and pextd instructions in a new unit called bit_sorter (so called because cfuged and pextd can be viewed as sorting the bits of the mask). The cnt* instructions and the popcnt* instructions now use the same OP_COUNTB insn_type so as to free up an insn_type value to use for the new instructions. The new instructions are implemented using a slow and simple algorithm that takes 64 cycles to compute the result. The ex1 stage is stalled while this happens, as for a 64-bit multiply, or for a divide when there is no FPU. Signed-off-by: Paul Mackerras <paulus@ozlabs.org> |
