There was no pattern to fold into these instructions. This patch adds the pattern obtained from the following ACLE intrinsics so that they generate sqdmlal/sqdmlsl instructions instead of separate sqdmull and sqadd/sqsub instructions: - vqdmlalh_s16, vqdmlslh_s16 - vqdmlalh_lane_s16, vqdmlalh_laneq_s16, vqdmlslh_lane_s16, vqdmlslh_laneq_s16 (when the lane index is 0) It also modifies the result of the existing pattern for the latter, when the lane index is not 0, to use the v1i32_indexed instructions instead of the v4i16_indexed ones. Fixes #49997. Differential Revision: https://reviews.llvm.org/D131700 |
