[cfe-users] No macros in DI metadata

[Bella V via cfe-users]

Thanks David for the helpful information. Is there a way to filter the
predefined macros such as __clang__, __GNUC__, etc.

I could not get the macros defined in my C code with the below code:
DIMacroNodeArray Macros = DICompUnit->getMacros();
for (auto *MN : Macros) {
    if (auto *M = dyn_cast<DIMacro>(MN)) {
        outs()<< M->getName();
    }
}
