Going through Highway's set of shuffle ops: 64-bit OddEven/Reverse2/ConcatOdd/ConcatEven, OddEvenBlocks, SwapAdjacentBlocks, 8-bit Reverse, CombineShiftRightBytes, TableLookupBytesOr0 (=PSHUFB) and Broadcast especially for 8-bit, TwoTablesLookupLanes, InsertBlock, InterleaveLower/InterleaveUpper (=vzip1/2). All of these are considerably more expensive on RVV. SVE has a nice set, despite also being VL-agnostic. |
