Sure, will do. |
The simulator library `libhexagon_rpc_sim.so` contains TVM runtime built into it, but since it's loaded as a "local" library these symbols are not visible to shared libraries loaded by subsequent dlopens. (Same applies to symbols from the C++ runtime.) To make these symbols visible, dlopen the defining libraries as "global". (Re-dlopeninig an already loaded library is a well-defined operation.)
