> @nsjian , kindly check the IR change, it may need some change in AARCH64 backend since now VectorStoreMask is not being inserted while connecting mask generating node to mask operation node. This saves redundant store mask operation if target supports predicate registers.

Hi @jatin-bhateja , thanks for the heads-up. The VectorMaskOp connection change looks reasonable. We will update SVE backend later.
