We already have PTX mma and mma.sp builtin support in #9909 and #10339 . However, we have not supported corresponding data movement builtins for these mma instructions, so the data movement would not be as fast as wmma. This PR brings the `ldmatrix` builtin, which is a native PTX warp-level instruction (https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#warp-level-matrix-instructions-ldmatrix), and we can use it to load several (1/2/4) 8x8 matrices from shared memory to warp memory. @vinx13 @Hzfengsy -- This is an automated message from the Apache Git Service.
