When I try to compile LLVM IR that was compiled from a C++ file, I find that the first time that ORCJIT looks up TLS variables is during the `J->initialize()` phase. However, for a C file, the same operation is performed during the` J->lookup('main') `step, which follows the initialization phase.
I know that compilers use different methods to compile C and C++ files, because C++ supports overriding but C does not. Therefore, when a compiler deals with symbols from C++, it needs to use mangling methods to ensure that each symbol is unique. So is it maybe caused by this? I cannot understand what the ORCJIT does when it is initialized, especially for symbols.
