使用场景。 TPACK 将两个对应的 Local U32 CUBE 字中的低位字节字段拼接起来，适用于按原始存储形式重排字段而不进行数值转换的场景。
工作方式。 对于每个活动字位置，source0 中选定的低位字节占据目标的低位字节，source1 中选定的低位字节紧随其后，目标中其余所有位均为零。
输入与结果。 source0 和 source1 是布局与几何形状匹配的 Local U32 CUBE_M16 或 CUBE_M32 Tile，pack_control 提供两个字段宽度，destination 是具有匹配布局与几何形状的新 Tile。
效果。 完整的控制信息与源数据校验先于完整定义的目标有效区域发布；源 Tile 保持不变，目标填充为 Null，且该操作不产生内存效果。
拒绝条件。 每个字段宽度必须在 1 到 3 之间，两者之和不得超过 4，控制位 63:32 必须为零，并且目标不得与任一源重叠；任何拒绝都发生在目标产生效果之前。
具体示例。 对于对应的源字 0x00001234 和 0x00ABCDEF，控制值 0x00000202 从每个源中选择两个低位字节，得到 0xCDEF1234。
