[GitHub] [tvm] syang-ng opened a new issue #8979: [Bug] Functions will crash when receiving NULL object 

syang-ng opened a new issue #8979:
URL: https://github.com/apache/tvm/issues/8979


   This issue is related to the problem mentioned in [discussion](https://discuss.tvm.apache.org/t/operators-will-crash-when-receiving-null-object/10988). Besides operators, I also found other TIR related functions will crash when receiving NULL object.
   
   To enhance the robustness of TVM, I log all these functions as a test case. I hope it can help TVM to fix this series of problems.
   
   ```python
   import tvm
   
   # tir.analysis
   tvm.tir.analysis.calculate_workspace_bytes(None, None)
   tvm.tir.analysis.detect_buffer_access_lca(None)
   tvm.tir.analysis.get_block_access_region(None, None)
   tvm.tir.analysis.get_block_read_write_region(None, None)
   tvm.tir.analysis.verify_gpu_code(None, None)
   tvm.tir.analysis.verify_memory(None)
   tvm.tir.analysis.verify_ssa(None)
   tvm.tir.analysis.BufferRegion(None, None)
   
   # tir.expr
   tvm.tir.expr.BufferLoad(None, None, None)
   tvm.tir.expr.Call(None, None, None, None)
   tvm.tir.expr.ProducerLoad(None, None, None)
   
   # tir.generic
   tvm.tir.generic.add(None, None, None)
   tvm.tir.generic.cast(None, None, None)
   tvm.tir.generic.divide(None, None, None)
   tvm.tir.generic.floordiv(None, None, None)
   tvm.tir.generic.multiply(None, None, None)
   tvm.tir.generic.subtract(None, None, None)
   
   # tir.op
   tvm.tir.op.abs(None, None)
   tvm.tir.op.ceil(None, None)
   tvm.tir.op.clz(None)
   tvm.tir.op.div(None, None, None)
   tvm.tir.op.floor(None, None)
   tvm.tir.op.floordiv(None, None, None)
   tvm.tir.op.floormod(None, None, None)
   tvm.tir.op.if_then_else(None, None, None, None)
   tvm.tir.op.indexdiv(None, None, None)
   tvm.tir.op.indexmod(None, None, None)
   tvm.tir.op.isfinite(None, None)
   tvm.tir.op.isinf(None, None)
   tvm.tir.op.isnan(None, None)
   tvm.tir.op.nearbyint(None, None)
   tvm.tir.op.power(None, None, None)
   tvm.tir.op.q_multiply_shift(None, None, None, None)
   tvm.tir.op.reducer(None, None, None, None)
   tvm.tir.op.round(None, None)
   tvm.tir.op.trunc(None, None)
   tvm.tir.op.truncdiv(None, None, None)
   tvm.tir.op.truncmod(None, None, None)
   tvm.tir.op.Call(None, None, None, None)
   
   # tir.stmt_functor
   tvm.tir.stmt_functor.ir_transform(None, None, None, None)
   tvm.tir.stmt_functor.post_order_visit(None, None)
   tvm.tir.stmt_functor.substitute(None, None)
   tvm.tir.stmt.Allocate(None, None, None, None, None, None)
   tvm.tir.stmt.BlockRealize(None, None, None, None)
   tvm.tir.stmt.BufferRegion(None, None)
   tvm.tir.stmt.MatchBufferRegion(None, None)
   ```

   Yep. I think TVM generally doesn't treat nullptr really seriously until we have `tvm::runtime::Optional` and "NOTNULLABLE" macros
