chaozju opened a new issue #5804:
URL: https://github.com/apache/incubator-tvm/issues/5804


   Is there a way to dump the Module to llvm ir into a `.s` file which can be later built to standalone executable by `clang` ?
   
   where I am:
   
   - dump an output from python following toturial
   ```python
   model_name = 'resnet18'
   model = getattr(torchvision.models, model_name)(pretrained=True)
   model = model.eval()
   
   scripted_model = torch.jit.trace(model, input_data).eval()
   mod, params = relay.frontend.from_pytorch(scripted_model,shape_list)
   
   with relay.build_config(opt_level=3):
       graph, lib, params = relay.build(mod,target='llvm',target_host='llvm',params=params)
   
   with open('/home/chao/tvm-playground/tvm-project/a.s','w') as f:
       f.write(lib.get_source())
   ```
   
   - assembling and linking with llvm backend
   ```bash
   llvm-as -o a.bc a.s
   llc -o a.o a.bc
   as a.o -o a.as
   cp ~/tvm/build/libtvm*.so ./
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD
   ld -L "./libtvm.so" "./libtvm_runtime.so" "./libtvm_topi.so" -o a.out a.as
   ```
   - result
   ```bash
   chao@DESKTOP-B79IRTG:~/tvm-playground/tvm-project$ ld -L "./libtvm.so" "./libtvm_runtime.so" "./libtvm_topi.so" -o a.out a.as
   ld: a.as: undefined reference to symbol 'memset@@GLIBC_2.2.5'
   //lib/x86_64-linux-gnu/libc.so.6: error adding symbols: DSO missing from command line
   ```
