With CONFIG_DEBUG_INFO_REDUCED, we do get quite a lot of debug info (around 22.7 MB for a defconfig+DEBUG_INFO_REDUCED). However, the "basenames must match" rule used by -femit-struct-debug-baseonly option means that we miss some core data structures, such as struct {device, file, inode, mm_struct, page} etc. We can easily get these included as well, while still getting the benefits of CONFIG_DEBUG_INFO_REDUCED (faster build times and smaller individual object files): All it takes is a dummy translation unit including a few strategic headers and compiled with a flag overriding -femit-struct-debug-baseonly. This increases the size of .debug_info by ~0.3%, but these 90 KB contain some rather useful info.
