Hi Masahiro, > On top of that, it is easier to add CONFIG_DEBUG_INFO_FULL or whatever. As per the prior discussion, Nick has convinced me that configuring an additional choice for a full debug info might cause more problems that it solves in general. >And, -g1 for CONFIG_DEBUG_INFO_REDUCED if you think it is worthwhile. This indeed would shrink the image size, but with this option enabled there would be no information about local variables which might surprise users of the option. So I don't really think it is worthwhile. Regards, Dmitrii.
