DEBUG_INFO build and compile times are reduced too.
Only works with newer gcc versions.
+config DEBUG_INFO_SPLIT
+ bool "Produce split debuginfo in .dwo files"
+ depends on DEBUG_INFO
+ help
+ Generate debug info into separate .dwo files. This significantly
+ reduces the build directory size for builds with DEBUG_INFO,
+ because it stores the information only once on disk in .dwo
+ files instead of multiple times in object files and executables.
+ In addition the debug information is also compressed.
+
+ Requires recent gcc (4.7+) and recent gdb/binutils.
+ Any tool that packages or reads debug information would need
+ to know about the .dwo files and include them.
+ Incompatible with older versions of ccache.
