JieGH opened a new issue, #17916: URL: https://github.com/apache/tvm/issues/17916
### Expected behavior Previously, my TVM setup was working as expected. TVM 0.18 with LLVM 19.3 Now upgrading both projects to the latest version: TVM 0.20.0 with LLVM 20.1.4, then ran the get started example code in `https://tvm.apache.org/docs/get_started/tutorials/quick_start.html` The code can not be executed with an error, In this code, the target is set as `target = tvm.target.Target("llvm -mattr=+m,+a,+f,+d,+zfh,+v,+c -vector-width=256")` ```bash % python basic_tvm.py # from tvm.script import ir as I # from tvm.script import relax as R @I.ir_module class Module: @R.function def forward(x: R.Tensor((1, 784), dtype="float32"), fc1_weight: R.Tensor((256, 784), dtype="float32"), fc1_bias: R.Tensor((256,), dtype="float32"), fc2_weight: R.Tensor((10, 256), dtype="float32"), fc2_bias: R.Tensor((10,), dtype="float32")) -> R.Tensor((1, 10), dtype="float32"): R.func_attr({"num_input": 1}) with R.dataflow(): permute_dims: R.Tensor((784, 256), dtype="float32") = R.permute_dims(fc1_weight, axes=None) matmul: R.Tensor((1, 256), dtype="float32") = R.matmul(x, permute_dims, out_dtype="void") add: R.Tensor((1, 256), dtype="float32") = R.add(matmul, fc1_bias) relu: R.Tensor((1, 256), dtype="float32") = R.nn.relu(add) permute_dims1: R.Tensor((256, 10), dtype="float32") = R.permute_dims(fc2_weight, axes=None) matmul1: R.Tensor((1, 10), dtype="float32") = R.matmul(relu, permute_dims1, out_dtype="void") add1: R.Tensor((1, 10), dtype="float32") = R.add(matmul1, fc2_bias) gv: R.Tensor((1, 10), dtype="float32") = add1 R.output(gv) return gv LLVM ERROR: Unimplemented reloc type: 55 [1] 9142 abort (core dumped) python basic_tvm.py ``` # Can someone provide some insight on this? I am using near identical build command for LLVM and TVM from my previous environment with TVM 0.19. # Thank you ### Environment I am using the latest OS, TVM and LLVM. ```bash % llc --version LLVM (http://llvm.org/): LLVM version 20.1.4 Optimized build with assertions.
