[GitHub] [tvm] mehrdadh opened a new issue #8049: AOT C Codegen lib0.c tvm__run_func function

mehrdadh opened a new issue #8049:
URL: https://github.com/apache/tvm/issues/8049


   Using AOT runtime with C codegen generates two library files: `lib0.c` and `lib1.c`
   `lib0.c` includes function declarations for aot runtime. When I use AOT with  micro target it generates `tvm__run_func` function signature twice as shown below:
   
   ```
   ...
   TVM_DLL int32_t tvm__run_func(TVMValue* args, int* type_code, int num_args, TVMValue* out_value, int* out_type_code);
   static TVMBackendPackedCFunc _tvm_func_array[] = {
       (TVMBackendPackedCFunc)fused_nn_conv2d_add_cast_multiply_add_right_shift_cast_add_clip_cast_clip_cast_s_9959535092109263429__1,
       (TVMBackendPackedCFunc)fused_reshape_cast_subtract,
       (TVMBackendPackedCFunc)fused_nn_contrib_dense_pack_add_fixed_point_multiply_add_clip_cast_cast_subtract_14669711146056581479_,

       (TVMBackendPackedCFunc)fused_cast_subtract,
       (TVMBackendPackedCFunc)fused_nn_avg_pool2d_cast,
       (TVMBackendPackedCFunc)fused_nn_softmax,
       (TVMBackendPackedCFunc)fused_nn_conv2d_add_cast_multiply_add_right_shift_cast_add_clip_cast_clip_cast,
       (TVMBackendPackedCFunc)fused_divide_add_round_cast_clip_cast,

       (TVMBackendPackedCFunc)_lookup_linked_param,
       (TVMBackendPackedCFunc)tvm__run_func,
   };
   ...
   
   TVM_DLL int32_t tvm__run_func(void* args, void* type_code, int num_args, void* out_value, void* out_type_code, void* resource_handle);
   ...
   ```

   Here is the target:
   tvm.target.target.micro("host", options=["-link-params=1", "--executor=aot"])

   This is because the micro target returns `-system-lib=1` by default.
   Thanks  @Mousius for pointing out!
