[GitHub] [tvm] vinx13 commented on issue #10831: [Bug][TIR][Script] TVM complains about undefined variables when building PrimFunc

   The issue here is `A_pack`, `B_pack` is allocated but not initialized. Without both writer and reader of the buffer being present, it cannot analyze the buffer shape and the allocation site correctly. We may want to add assertions in `PlanAndUpdateBufferAllocationLocation` make sure that buffer is initialized and avoid user confusion. cc @Hzfengsy 
   If you would like to keep buffer shape and allocation location as specified in TIR, you can disable `tir.CompactBufferAllocation` and `tir.PlanAndUpdateBufferAllocationLocation` passes. See also https://github.com/apache/tvm/issues/10877
