--- Comment #2 from Jan Dubiec <jdx at o2 dot pl> --- One more thing – the documentation on the webpage states that -mn "must be used either with -mh or -ms". It is true for old compilers (e.g. for gcc 4.7 which I still use) but does not seem to be true for new ones, i.e. it is possible pass -mn alone at least to gcc 12.2. BTW. As far as I can see support for H8/300 (pure 16-bit MCUs, do not confuse with H8/300H) has been (justifiably) removed since mid-2020 – IMO it is worth to mention about that fact in the documentation.
