We've investigated one reason why debugging information often goes wrong at https://reviews.llvm.org/D152095. > LLVM can't handle IR where subprogram definitions are nested within DICompositeType when doing LTO builds, > because there's no good way to cross the CU boundary to insert a nested DISubprogram definition in one CU into a type defined in another CU.
