How about simply assigning DEBUG_CFLAGS := -g at the very beginning without any conditions? This would provide the default with the possibility of overriding later and -gsplit-dwarf does not necessarily come with -g implicitly. > Honestly, I really don't think we need to be wrapping every compiler > command line flag under the sun in a kconfig option. This indeed sounds reasonable to me. So the key point here is to not bloat the kconfig with options related to every compiler flag. But I think it still might be useful to provide some option that would include sort of full debug information compilers may produce. With this approach there would be, in fact 3 different levels of debug information supported by Kconfig: reduced, default and full. The full level would increase everything like -g3, and -fdebug-macro for Clang, and probably others. > Or add -g1 to CONFIG_DEBUG_INFO_REDUCED. I ran some tests and there was indeed some decrease in size. That combination probably might be useful. Any thoughts? Regards Dmitrii
