[cfe-users] No macros in DI metadata

[Bella V via cfe-users]

Hello All,

I'm trying to build a list of macros in a compilation unit using CU->
getMacros

().
I do not see the macros field in DICompileUnit output.
*https://godbolt.org/z/b8cM1Yf7v *

Please let me know what I'm missing.

Many Thanks.

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(MN)) {
outs()<< M->getName();
}
}

You could check where the macro is defined, I guess?
If it's in a DIMacroFile i guess it's not a compiler builtin. It might
still be from a system header, etc, if that matters to you - so then
you'd have to filter by the DIMacroFile's 'file' attribute.
