@adrian-prantl @JDevlieghere - perhaps one of you/your cohort might have further insight on stabs? (I believe they're used in the macho debug info model - but perhaps they're only generated by the linker? So maybe we don't have code in the llvm subproject that can generate them for testing? - but could at least include instructions on how to generate them with lld or something to include in the test case for future maintenance?)
