## 载体 x[8:16, :]：数值检查通过
{ s0: sadd.s32 s9, 16, s0 ;
{ s0: @p0 dma.simple [vmem:s10], [hbm:s9], length=16, dst_flag=[sflag:52] }
{ misc: @p0 vwait.ge [sflag:52], 16 ;
{ s0: @p0 dma.simple [hbm:s1], [vmem:s10], length=16, dst_flag=[sflag:52] }
{ misc: @p0 vwait.ge [sflag:52], 16 ;
{ misc: vwait.ge [sflag:45], 1 ;

## 改写后：原 DMA 之前插入 4 个 bundle，原 DMA 换成第二段
{ s0: sadd.s32 s11, -13, s9 ; s1: simm.s32 s12, 5 }
{ s0: simm.s32 s13, 8 ; s1: sadd.s32 s14, 5, s10 }
{ s1: simm.s32 s15, 3 }
{ s0: @p0 dma.strided [vmem:s10], [hbm:s11], length=10, dst_stride=s13, src_stride=s13, elements_per_stride=s12, dst_flag=[sflag:52] }
{ s0: @p0 dma.strided [vmem:s14], [hbm:s9], length=6, dst_stride=s13, src_stride=s13, elements_per_stride=s15, dst_flag=[sflag:52] }
结果等于 x[3:11, :]，数值检查通过
