Alan Li	ac65b2c327	[MLIR][GPU] Add a pattern to rewrite gpu.subgroup_id (#137671) ... This patch impelemnts a rewrite pattern for transforming `gpu.subgroup_id` to: ``` subgroup_id = linearized_thread_id / gpu.subgroup_size ``` where: ``` linearized_thread_id = thread_id.x + block_dim.x * (thread_id.y + block_dim.y * thread_id.z) ```	2025-04-29 10:54:48 -04:00
