~ShuffleCostEstimator () | |
Merges shuffle masks and emits final shuffle instruction, if required.
It supports shuffling of 2 input vectors. It implements lazy shuffles emission, when the actual shuffle instruction is generated only if this is actually required. Otherwise, the shuffle instruction emission is delayed till the end of the process, to reduce the number of emitted instructions and further analysis/transformations.
