Hi All, I have a program that uses C++ STL a lot. To have the source code for STL functions, I undefined "_GLIBCXX_EXTERN_TEMPLATE" in c++config.h. In spite of this, after compilation (via clang) and linking (via llvm-ld), the resulting bitcode contains a few declared functions (with no definitions). My question is: In the scenario where some function definitions are missing in a llvm bitcode, can we get a way to run thi...

...interpretation. Then another question emerges: Is there a way to determine the necessary libraries in need? And where to locate these necessary libraries?
