+config DEBUG_INFO_REDUCED
+       bool "Reduce debugging information"
+       depends on DEBUG_INFO
+       help
+         If you say Y here gcc is instructed to generate less debugging
+         information for structure types. This means that tools that
+         need full debugging information (like kgdb or systemtap) won't
+         be happy. But if you merely need debugging information to
+         resolve line numbers there is no loss. Advantage is that
+         build directory object sizes shrink dramatically over a full
+         DEBUG_INFO build and compile times are reduced too.
+         Only works with newer gcc versions.
