Please give me some examples for "more codepaths" enabled by DEBUG_INFO because this is the opposite to the previous decision. Commit f9b3cd24578401e7a392974b3353277286e49cee mentions: all*config target ends up taking much longer and the output is much larger. Having this be "default off" makes sense. allmodconfig is often used for compile testing in CI/CD. We need to see the sufficient gain that sacrifices the build speed. -- Best Regards Masahiro Yamada
