llvm dev - Apr 2019 - Distinguishing Between User-Defined and Library Functions in LLVM IR

Hello,

I would like to ask whether there is a definite way to distinguish between
user-defined and library functions in an LLVM IR Pass (IR emitted by Clang from
C++, if it matters, but would prefer a cross-language solution).

I tried checking for unmangled names, linkage etc., but did not manage to find
an accurate solution.

Thank you very much in advance. 🙂

I don't think there is any logical boundary between "user" code
and library
code - they're all user code, just written by different users.
